A^ Analytical Notices of Books. 



colours are produced by silky hairs ; the woolly ones, which are 

 brown, being entirely hidden. The moustaches of the lips are 

 black, while those of the eyes are white. The snout is short, 

 and strongly separated by a depression from the cerebral portion 

 of the head, which is remarkable for its capacity. The length 

 from the tip of the nose to the posterior part of the body in the 

 young individual described, was three and a half feet ; the height 

 to the shoulders being fifteen inches. It inhabits the Cordilleras 

 of Chili, and has received from M. F. Cuvier the trivial name of 

 ornaius. 



It is much to be regretted that the able author of this notice 

 has limited his remarks to the mere colour of the hairs, without 

 entering into those details which in the present advanced state of 

 Zoology, are indispensable to a proper acquaintance with the 

 subject. From his description it is impossible to discover to which 

 of the subgenera of the Linnasaa Ursus the present species should 

 be referred, which is so entirely new with respect to geographical 

 distribution, that doubts will naturally be excited whether it is 

 not also novel iu form. The somewhat projecting upper lip, 

 which may be observed in the figure, appears to connect it with 

 the Prochilus of lUiger, and with the Helarctos of Dr. Horsfield, 

 described in our last number. We trust that M. F. Cuvier will 

 hereafter develope its scientific characters, and thus enable us, 

 possessing as we now do Bears from almost every quarter, to fix 

 upon a stable basis the subgenera of this very interesting group. 



In describing the Souslik, (Jrctom^s Citillus L.) M. F. Cuvier 

 recurs to the fact of his having established some years since in the 

 Memoires du Museum d'Histoire Naturelle, a genus under the name 

 of Spermophilus, of which the present animal, the C. guttatus of 

 Pallas, forms the type. It is intermediate between the Marmots 

 and the Tamias, or (hose species of burrowing Squirrels which are 

 provided with cheek pouches, and feed on seeds. With these 

 latter the Spermoj)hilus guttatus agrees in habits, and in the 

 slender proportions of its head, while it approaches the Marmots 

 by the thickness of its general form. With both these groups it coin- 

 cides in the number of its teeth, and even in their form ; except 

 that the molar teeth are narrower, their first tubercle being very
