From our author's account, Texas would undoubtedly furnish its full quota of contributions to a cabinet of natural history. The feathered tribes luxuriate there, especially on the coast, in great abundance and variety. The wild fowl congregate in prodigious flocks, and the ornithologist might find almost every order, genera and species in creation. The tenants of the forest are not less numerous,--there being an ample supply of wolves, bears, panthers, wild cats, wild hogs, foxes, rackoons and squirrels. The waters too, furnish their finny, testaceous and crustaceous treasures,--the red fish, buffalo, cat, drum, pearch, oysters, crabs, &c. Nor is there any want of those amphibious annoyances, crocodiles and alligators--and to crown the whole, there is an anomalous species called the alligator-garr,--consisting not of the fanciful compound of half horse and half alligator--but of the actual and bona fide admixture of one moiety of fish, and the other of alligator. We must not forget either in enumerating the zoological curiosities of that region, one which we do not recollect to have seen described by naturalists. We give the words of the author. One of the prettiest little animals I ever saw, is the "horned frog;" which, notwithstanding its name, is far from being amphibious, as it is found on the prairies at a distance from water. Indeed it bears little or no resemblance to a frog, appearing more like a lizard, with rather a long and graceful form, a tail, and legs of nearly equal length, so that it runs swiftly and never leaps. I had often occasion to notice them, both here and on other prairies. They run with such agility, that although they do not take alarm until you have approached very near them, they dart off, and generally disappear immediately. One might often mistake them for quails, while in motion. They are of a yellowish color, mottled, and have horns about half an inch long, projecting from the front of the head. Several were caught and kept for some time in a barrel at Anahuac, and though it could not be perceived that they ate any of the various kinds of food which were offered them, they lived and continued active for a considerable time. That formidable reptile the rattlesnake, is also found in the grassy prairies of Texas. Our traveller killed one of the "largest and noblest" of that venemous family--it being five or six feet long and about six inches in circumference. It was provided however with only eight rattles, whereas others which had been killed a few days previously of hardly half the size, were furnished with as many as thirteen;--from which the author takes occasion to contest the common opinion that the number of rattles is an indication of the reptile's age. We have heard the same fact asserted, and the same conclusion drawn from it by others, whose opportunities for careful and actual observation were undoubted.
