    宝马系统彩票It is not without much hesitation that we have adopted for this animal the generic name of Canis, and referred it, in conformity with the example of most of the leading zoologists of the day, to the same group with the Wolf, the Jackal, and the Fox; from all of which it differs in such important particulars as fully entitle it, in our estimation, to the rank of a distinct and separate genus. To this rank it has, indeed, been already raised by Mr. Brookes, under the generic appellation of Lycaon; but as we are not aware that it has been any where described under that name, or that any detailed account has been given of the characters on which that separation[78] is founded, we cannot consider ourselves authorized in a work of this nature to make any innovations upon science, however much we may feel, as in the present instance, that they are called for by the exigency of the case. That its position is at least doubtful is proved by the fact that M. Temminck, one of the ablest of the continental zoologists, first described it from the living animal under the designation of a Hy?na, and, having subsequently changed his opinion, is now disposed to regard it as a species of dog.

    宝马系统彩票官方简介:

    If the Boas furnish the most terrible examples of the tremendous powers of destruction possessed by a few of that division of the Serpent tribe, whose bite is unattended with the effusion of venom, the Rattlesnakes afford a no less remarkable instance of the dreadful malignity of the poison with which others of the tribe are so abundantly supplied. This poison is secreted by a gland of considerable size situated beneath the eye, the excretory duct of which terminates on each side at the base of a long and tubular fang in the upper jaw, which is concealed while the animal is at rest in a fold of the gum, but is capable of being instantaneously[240] erected when he is irritated, and affords at the same time the means of inflicting the wound and of insinuating into it the deadly fluid with which it is charged. In the Rattlesnakes these two fangs are the only visible teeth implanted in the upper jaw; but behind each of them are several rudiments of others by which they are from time to time replaced. Their other distinguishing characters consist in the whole of the transverse plates which cover the under surface of the body and of the tail being simple, and in the singular apparatus by which the latter is terminated, and which is formed of a series, more or less numerous according to the age of the individual, of flattened rings loosely attached one within the other in such a manner as to produce a peculiar rattling sound when the tail is moved with any degree of quickness. The number of rings commonly varies from five to twelve; but in very old specimens it is said to have been found to exceed forty.
