During the colder months these reptiles remain in a torpid state.
These great reptiles may attain a length of To ft.; they feed on small animals which they crush to death in their folds.
Starting from the basis " that the phrase `birds are greatly modified reptiles' would hardly be an exaggerated expression of the closeness " of the resemblance between the two classes, which he had previously brigaded under the name of Sauropsida (as he had brigaded the Pisces and Amphibia as Ichthyopsida), he drew in bold outline both their likenesses and their differences, and then proceeded to inquire how the A y es could be most appropriately subdivided into orders, suborders and families.
Among reptiles the various kinds of lizard are noticeable.
Dvina, Glossopteris, Noeggerathiopsis and other ferns characteristic of the Indian Gondwana beds have been found; and with these are numerous remains of reptiles similar to those which occur in the Indian deposits.
It was quickly seen - even by those who held Archaeopteryx to be a reptile - that it was a form intermediate between existing birds and existing reptiles; while those who were convinced by Sir R.
The majority of spiders, however, are soft-skinned and succulent, and are tasty morsels for insectivorous reptiles, birds and mammals.
Reptiles are scarce, and venomous reptiles unknown.
No doubt large numbers are devoured by insectivorous birds, mammals and reptiles, but the mortality due to them and other foes sinks into insignificance beside that caused by the persecution of hymenopterous insects of the families Ichneumonidae and Pompilidae, especially of the latter, many species of which systematically ransack the country for spiders wherewith to feed their young in the breeding season.
Reptiles are scarce, and venomous reptiles unknown.
In the Tableau Elementaire, published in 1795, Cuvier adopts Linnaeus's term in its earlier sense, but uses the French word "Reptiles," already brought into use by Brisson, as the equivalent of Amphibia.
In 1816, de Blainville, 4 adopting Latreille's view, divided the Linnaean Amphibia into Squamiferes and Nudipelliferes, or Amphibiens; though he offered an alternative arrangement, in which the class Reptiles is preserved and divided into two subclasses, the Ornithoides and the Ichthyoides.
How many other reptiles lurked in the trees and brush, ready to waylay anyone bold enough to enter their territory?
As for reptiles, Australia has a few tortoises, all of one family, and not of great size.
This so-called third, upper or posterior conch is not a true conch, nor is that of the vestibulum; only the middle one forms a scroll, and this corresponds to the only one of reptiles and the lower of the mammals.
As regards reptiles, there are at least seven poisonous snakes - two cobras, two puff-adders and three vipers.
In the author's concluding summary he remarks on the fact that, while the Odontolcae, as exhibited in Hesperornis, had teeth inserted in a continuous groove - a low and generalized character as shown by reptiles, they had, however, the strongly differentiated saddle-shaped vertebrae such as all modern birds possess.
The separation of the Ratitae from the other birds, and their seemingly fundamental differences, notably the absence of the keel and of the power of flight, induced certain authors to go so far as to derive the Ratitae from the Dinosaurian reptiles, whilst Archaeopteryx (q.v.) and the Carinatae were supposed to have sprung from some Pterosaurian or similar reptilian stock.
Every bayou contains alligators; and reptiles of various species, such as turtles, lizards, horned toads, rattlesnakes and moccasins are abundant.
Reptiles are numerous.
The list of reptiles includes the venomous Vipera ammodytes and Pelias berus, while scorpions and lizards infest the stony wastes of the Karst.
The reptiles (tortoises) are also nearly allied to the Mascarenes and Madagascar species which once existed.

The reptiles include the ringed-snake, slow-worm, viper and lizard.
Oxyuris, though chiefly parasitic in the Mammalia, occurs also in reptiles, Amphibia and one or two insects.
The discovery of their true nature was made by Dr William Buckland, who observed that certain convoluted bodies occurring in the Lias of Gloucestershire had the form which would have been produced by their passage in the soft state through the intestines of reptiles or fishes.
The scope of the anatomical part of the following article is a general account of the structure of birds (A y es) in so far as they, as a class, differ from other vertebrates, notably reptiles and mammals, whilst features especially characteristic, peculiar or unique, have been dwelt upon at greater length so far as space permitted.
There are only two or three vertebrae which are equivalent to those of the reptiles; these true sacrals are situated in a level just behind the acetabulum; as a rule between these two primary sacral vertebrae issues the last of the spinal nerves which contributes to the composition of the sciadic plexus.
13), consisting of the sacrum (already described) and the pelvic arch, namely ilium, ischium and pubis, it follows that only birds and mammals possess a pelvis proper, whilst such is entirely absent in the Amphibia and in reptiles with the exception of some of the Dinosaurs.
Thus it has come to pass that the muscles of the hind limbs are, like their framework, more easily compared with those of reptiles and mammals than are the wings, whilst within the class of birds they show an enormous amount of variation in direct correlation with their manifold requirements.
We have here the interesting fact that a muscle (portion of the triceps humeri of the reptiles) has been reduced to a tendon, which in a secondary way has become connected with cutaneous muscles, which, when strongly developed, represent its belly.
In comparison with reptiles the cerebellum of birds shows high development.
All birds have, like most reptiles, a well-developed third lid or "nictitating membrane," which moves from the inner canthus obliquely upwards and backwards over the cornea.
The moving mechanism is a further and much higher development of that which prevails in reptiles, there being two muscles completely separate from each other.
Although the scala tympani is so rudimentary, not reaching a higher level than in most of the reptiles, and remaining far below the mammalia, birds do not only hear extremely well, but they distinguish between and " understand " pitch, notes and melodies.
The principal reptiles are a lizard, a tortoise, the vivora de la crux (a dangerous viper, so called from marks like a cross on its head) and the rattlesnake in Maldonado and the stony lands of Minas.

Nature has provided several species of animals, birds and reptiles, to feed upon these insects, and various poisonous and suffocating compounds are used to destroy them, but with no great degree of success.
1522), was essentially a compilation, more or less critical, of all such records, pictures and relations concerning beasts, birds, reptiles, fishes and monsters as could be gathered together by one reading in the great libraries of Europe, travelling from city to city, and frequenting the company of those who either had themselves passed into distant lands or possessed the letters written and sometimes the specimens brought home by adventurous persons.
1 The anatomical error in reference to the auricles of Reptiles and Batrachians on the part of Linnaeus is extremely interesting, since it shows to what an extent the most patent facts may escape the observation of even the greatest observers, and what an amount of repeated dissection and unprejudiced attention has been necessary before the structure of the commonest animals has become known.
Owen not only occupied himself with the dissection of rare animals, such as the Pearly Nautilus, Lingula, Limulus, Protopterus, Apteryx, &c., and with the description and reconstruction of extinct reptiles, birds and mammals - following the Cuvierian tradition - but gave precision and currency to the morphological doctrines which had taken their rise in the beginning of the century by the introduction of two terms, " homology " and " analogy," which were defined so as to express two different kinds of agreement in animal structures, which, owing to the want of such " counters of thought," had been hitherto continually confused.
Among reptiles the Egyptian cobra seems to be indigenous in the south, where also is found the dreaded horned viper.
Of reptiles Japan has only 30 species, and among them is included the marine turtle (urni-ganie) which can scarcely be said to frequent her waters, since it is seen only at rare intervals on the southern coast.
