1806, Charles Linné [i.e., Carl Linnaeus], “Order V. Pecora.”, in William Turton, transl., A General System of Nature, through the Three Grand Kingdoms of Animals, Vegetables, and Minerals: […] In Seven Volumes, volumes I (Animal Kingdom.—Mammalia. Birds. Amphibia. Fishes.), London: Printed for Lackington, Allen, and Co. […], →OCLC, section 38 (Antilope), page 112:

MALIMBA BEE-EATER. [...] Cinereo-violaceous Bee-Eater, sanguine rose-coloured beneath, with black eye-stripe, white throat, and two lengthened tail-feathers.

1812, George Shaw, General Zoology, or Systematic Natural History, volume VIII, part 1 (Aves), London: Printed for Kearsley, Wilkie and Robinson, [et al.], →OCLC, page 174:

These two birds somewhat closely resemble each other, but the Sedge Warbler is russet-brown above, the feathers with dark centres, the pale buff eyestripe is very clearly defined, and the underparts are buffish white; the Reed Warbler is more olive on the upper parts, the feathers having no dark centres, the underparts are more inclined to buff, and the eyestripe is nearly obsolete.

1891, Charles Dixon, “Ramble VI. By Lakes and Streams.”, in The Birds of Our Rambles: A Companion for the Country, London: Chapman and Hall, Limited, →OCLC, page 130:

The plumage pattern of the red-backed shrike male is conspicuous from a long distance. This pattern, not the feathering, is all-important since a plain plastic model is as effective as a stuffed mount in eliciting mobbing by pied flycatchers. Removal of the conspicuous eye stripe (including the equally dark eye) renders the model almost ineffective[…].

1993, E. Curio, “Proximate and Developmental Aspects of Antipredator Behavior”, in Advances in the Study of Behavior, volume 22, San Diego, Calif., London: Academic Press, →ISBN, →ISSN, →OCLC, section II (Causal Aspects of Enemy Recognition), page 150:

Once in a while a design feature shows up in animals that are not closely related. A good example is the eyestripe coloration pattern, which appears in sparrows, antelopes, and chipmunks. In all these creatures, a dark facial stripe runs from the snout to the eye. [...] Presumably eyestripes serve as protective coloration in all these prey animals, disguising their eyes from predators.

2009, James Gurney, “Dinosaurs”, in Imaginative Realism: How to Paint what Doesn’t Exist, Kansas City, Mo.: Andrews McMeel Publishing, →ISBN, page 94, column 1:

The eye-stripe is exactly that: a stripe through the eye. When present, this is a dark line that usually extends from the bill back through the eye. On some birds, it extends just from the eye back, leaving the lores (the area between the eye and the bill) pale and unmarked.

From sibli(ng) + -cide (suffix meaning ‘killing; killer’).

suffix

I continue to question the interpretation of "fatal sibling aggression" and active brood reduction as a means of maximizing productivity[…]. To me, the data clearly indicate a simple response to food availability, with the oldest young passively out-competing its smaller sibling for a limited resource. I still have not seen data to support "siblicide" as a strategy.

1981 winter, Ralph W. Schreiber, “Book Review: The Eastern Bering Sea Shelf: Oceanography and Resources, 1981. Edited by D. W. Hood and J. A. Calder. 2 Volumes. 1339 pp. Available from the University of Washington Press, Seattle, WA 98105. $65.00/volume.”, in Pacific Seabird Group Bulletin, volume 8, number 2, Stinson Beach, Calif.: Pacific Seabird Group, →OCLC, page 111:

Oophagy and adelphophagy, which are forms of embryonic cannibalism, occur in both cartilaginous and bony fishes. They are variations on the tactic of siblicide (Mock, 1984) as a reproductive strategy. In oophagy, embryos feed upon sibling eggs. […] Adelphophagy, literally eating one's brother, is also known in sharks as intrauterine embryonic cannibalism[…].

1988, John P. Wourms, Bryon D. Grove, Julian Lombardi, “The Maternal–Embryonic Relationship in Viviparous Fishes”, in W. S. Hoar, D. J. Randall, editors, Fish Physiology, volumes XI (The Physiology of Developing Fish), part B (Viviparity and Posthatching Juveniles), San Diego, Calif.: Academic Press, →ISBN, page 43:

Obligate siblicide is best known in various eagles, boobies, and pelicans. All lay two eggs, hatching is asynchronus, and usually the elder sib kills its younger sib soon after hatch. From the parent's perspective, the second egg/chick serves as insurance against the unexpected failure of the first[…]. Interestingly, obligate siblicide seems to be independent of prevailing food at the time of the junior sibling[']s demise.

1994, L. Scott Forbes, Douglas W. Mock, “Proximate and Ultimate Determinants of Avian Brood Reduction”, in Stefano Parmigiani, Frederick S. vom Saal, editors, Infanticide and Parental Care […] (Ettore Majorana International Life Sciences Series; 13), Chur, Switzerland, Camberwell, Victoria: Harwood Academic Publishers, →ISBN, page 245:

If siblicides are victim-based, a mother clearly cannot improve her fitness by producing fewer eggs. Less obviously, mothers may eventually be able to gain by laying more, until eventually they are constrained by the costs of eggs.

1997, Douglas W. Mock, Geoffrey A[lan] Parker, The Evolution of Sibling Rivalry (Oxford Series in Ecology and Evolution), Oxford, Oxfordshire: Oxford University Press, →ISBN, page 230:

One of the more recent examinations of siblicide cases is [John M.] Dawson and [Patrick A.] Langan's Special Report on Murder in Families, published through the Bureau of Justice Statistics (1994). […] According to their findings, 85% of siblicide offenders and 73% of siblicide victims were male. […] Alcohol was reported to play a role in approximately one half of the siblicides in Dawson and Langan's study.

The presence of eponychium (also called “foal slippers”) on the feet (Figure 172-3) is indicative that the foal has not yet stood.

In ungulates, this is apparently exaggerated by the presence of the eponychia, or collagenous pads over the sole of the fetal hoof.

2015, Donald M Broom, Andrew F Fraser, Domestic Animal Behaviour and Welfare, 5th edition, page 196:

/ʌŋˈɡjuːləˌɡɹeɪd/

From Latin ungula (“claw, hoof”) + -grade (“means of walking]”) (from Latin gradus). Compare French ongulograde.

It has perhaps not been observed hitherto that the terms Digitigrada, Unguligrada, and Plantigrada fully apply to the Arthropoda, or that the manner in which the animals treat the ground and the corresponding structure of their feet deserve special attention as distinctive characters of classes and orders in this series of the animal kingdom; yet it is so. […] All Crustacea (including the Myriapoda, which merely exhibit the Crustacean type modified for terrestrial life) are Unguligrada; and the same is the case with all larvæ of Insects with complete metamorphosis, and with some of the lower groups of Insects, especially Thysanoura and Siphunculata—the unguligrade Arthropoda being at the same time, with few exceptions, also Solipeda.

1865 March, J. C. Schjödte [i.e., Jørgen Matthias Christian Schiødte], “XXII.—On the Classification of Cerambyces, with Particular Regard to the Danish Fauna.

Babington, John Edward Gray, William Francis, editors, The Annals and Magazine of Natural History, including Zoology, Botany, and Geology, volume XV (3rd series), number 87, London: Printed and published by Taylor and Francis, →OCLC, pages 182–183:

That excessive development of the epidermis which gives rise to a nail takes place, in the Horse, not only upon the dorsal surface of the terminal joint of the digit, but upon its ventral surface and sides, and thus produces a hoof. The animal is supported by these greatly-developed nails, and hence is said to be unguligrade.

The subjects of this book are the animals I will designate as megaherbivores. […] Such animals have been colloquially designated pachyderms; but a thick skin is a minor feature, and it is their very large body size that sets these few species apart from the numerous smaller species of unguligrade herbivore that occupy a wide variety of terrestrial ecosystems today.

sinupalliate

But even this new conception would not furnish the clew to the law of torsion as long as the hinge line is considered (as by Jackson) one radius of the angle of torsion; with Noetling's data a comparison of the valves of Nucula with any sinupalliate pelecypod valve shows, that though in both the axis of the hinge is parallel to the oro-anal axis, a torison^([sic]) of 90° of the valve of Nucula has taken place with reference to that of the sinupalliates.

1903, The American Geologist, volume 31, page 35:

Larger suspension feeders are also very abundant, such as the endobyssate bivalve Hoernesia with shell torsion and a thick umbo used as an anchor (McGHEE, 1978), as well as the deep-burrowing sinupalliate Pleuromya.

1996, Richard W. Merritt, An Introduction to the Aquatic Insects of North America, page 126:

Subimagos emerge at the surface, fly to a support, molt immediately to the adult stage, live only a few hours, swarm, and mate shortly after ecdysis.

2009, James H. Thorp, Ecology and Classification of North American Freshwater Invertebrates:

Subimagines flutter away immediately and rest at protected sites near the stream for up to 2-3 days, until the molt to the very short-lived adult occurs.

hydrophore

It is, in our opinion, unfortunate that the term "hydrophore" has come into general use for this rudimentary form of hydrotheca.

1907, Sydney John Hickson, Hydroid zoophytes, page 26:

Thus if Phylactothcca is to be regarded as a valid genus, it can only be, on the basis of Billard's definition, if the hydrophores are definitely not of the typical Halecium-form.

1938, Proceedings of the Royal Society of Victoria, page 314:

The very short hydrophore pedicel projects from a shelf-like process near the distal end of the internode, which is not enlarged where the hydrophore appears.

1946, Charles McLean Fraser, Distribution and Relationship in American Hydroids, page 276:

amphistomous

Some entozoa are amphistomous.

1875 April, “Miscellany: Food of the Bongos”, in Popular Science, volume 6, number 41, page 766:

In many a pylom occurs also at the aboral pole, so that the shell, perforated by a mouth at both poles of the principal axis, acquires an amphistomous character.

1889, The Annals and Magazine of Natural History - Volume 4, page 302:

Some shells of an amphistomous Rhizopod were observed from near Recess, W. Ireland, which probably pertained to this genus. The shells were chitinoid, yellow in colour, and each aperture was situated on a slight protuberance.

1901, Pamphlets on Protozoology (Kofoid Collection):

Arendt and coworkers propose that the blastopore in this species is amphistomous, giving rise to both mouth and anus.

2009, Daniel H. Shain, Annelids in Modern Biology, page 108:

Contrary to the view of Cable (1974), we do not consider larvae of this species as amphistomous.

[The bots] were hatched, into (what is called in the country) a horse-bee or nitter.

1809, Medical Repository of Original Essays and Intelligence Relative to Physic, Surgery, Chemistry, and Natural History, volume 12, page 124:

The last three species are the nitters so well known in this country; particularly the leg and throat nitters. It is the received opinion that the nits on the legs of horses, are taken into the mouth of the horse, conveyed into the intestines, and at length become the bot larva.

1826, Amos Eaton, Zoological Text-book Comprising Cuvier's Four Grand Divisions of Animals, page 226:

If the "throat nitter" (Œ veterinus) is the true bot however, […] it must be evident that the remedy proposed […] is at least doubtful […]

meleagrine

Having disposed of such records as we have of the extinct ancestors of the American turkeys — the so-to-speak meleagrine records — we can now pass to what is, comparatively speaking, the modern history of these famous birds, although some of this history is already several centuries old.

1914, Edward A. McIlhenny, The Wild Turkey and Its Hunting, Doubleday, page 39:

To use the district court's meleagrine analogy, one may add an additional step to the recipe: "continuing to cook the turkey until the skin is burned to a crisp."

2003, United States Patents Quarterly, volume 65, page 1968:

The sad incident with the turkeys is hardly the first case of an improper response to wild animals that have wandered out of their natural habitat. […] Perhaps this aquiline newspaper would like to memorialize its late meleagrine friends by publishing posters or essays from Berkshire schoolchildren and scout troops.

11 October 2005, “Henpecking is not the solution”, in The Berkshire Eagle:

1940 January, Erwin C. Stumm, “Upper Devonian Rugose Corals of the Nevada Limestone”, in Journal of Paleontology, volume 14, number 1, page 64, column 1:

Tabulae are transverse plates which may be flat, convex or concave. They usually occupy a central space or tabularium, and if there is an axial complex they join with it. […] Dissepiments, the small plates usually found towards the edge of the corallum, lie peripheral to the tabularium and like the tabulae are constructed of fibro-normal tissue.

1979, E[uan] N[eilson] K[err] Clarkson, Invertebrate Palaeontology and Evolution, London, Boston, Mass., Sydney, N.S.W.: George Allen & Unwin, published 1983, →ISBN, page 74, columns 1–2:

If further investigation shows that clinotabulae are absent from the Geyerophyllidae and biform tabularia are developed, then the Geyerophyllidae should be placed in synonymy with the Petalaxidae.

tupaiid

Some authors rank tupaiids in a separate order Tupaioidea (Martin, 1966), while others retain them among the Primates (Napier and Napier, 1967) or 1nsectivora (Hill, 1953b).
The uncertainty surrounding tupaiid phylogeny is a consequence of an inadequate fossil record.

1987, F. A. Jenkins, Jr., “1: Tree Shrew Locomotion and the Origins of Primate Arborealism”, in John G. Fleagle, editor, Primate Evolution and Human Origins, page 2:

Dental characters have proven to be of little use as there is no Paleocene tree shrew, which would show more primitive tupaiid dental characters. From the dentition of living tupaiids, one would easily infer that all of them have derived characters that prevent them from being ancestral to primates, among which [are] specializations in their dentitions or molar characters in tupaiines (see Butler, 1980).

2007, Marc Godinot, “Chapter 4: Primate Origins: A Reappraisal of Historical Data Favoring Tupaiid Affinities”, in Matthew J. Ravosa, Marian Dagosto, editors, Primate Origins: Adaptations and Evolution, page 120:
