ORDER RUMINANTIA. 137 



white specimens are not uncommon. This species resides 

 in the open plains, and not in swampy woods, like the pre- 

 ceding 1 . It is very fleet, and in the heat of its course the male 

 emits a powerful smell of onions, which is perceptible at 

 four hundred yards' distance. M. Desmarets states that he 

 received a horn, which he considers of this species, brought 

 from Port Desire, on the coast of Patagonia. Hence it 

 would appear that they spread nearly over all South Ame- 

 rica ; but these horns, according to Baron Cuvier, become 

 flattened and prismatic in form, with a second snag to the 

 rear below, and one (fig. 48, pi. 3, vol. iv. Oss. Foss.) brought 

 from the south of Brazil, had several snags upon each fork, 

 approaching, in a diminutive form, to those before de- 

 scribed under the head of C. Mexicanus. It is, perhaps, 

 proper to remark, in support of what was before said on 

 the flattening of Deer's horns, that this occurs again in a 

 specimen where the latitude is subject to snow. 



The Cariacou Deer. (Cervus Nemoralis, Nob.J This lit- 

 tle animal appears to be the last of this group, and the 

 smallest of the species or varieties of Virginian Deer. It 

 exists principally in the woody regions of tropical America, 

 and, as it would seem, as far north as the southern parts of 

 the United States. The Baron figures a series of the horns, 

 fig. 18, 19, 20, 21, 22, and 23, of plate v., under the names 

 of Cariacou, Biche de la Louisiane, Biche de Cayenne, Cerf 

 Blanc, Cerf des Paletuviers, &c. We consider it as the 

 Squinaton of Dobbs; and it may be even the Jumping 

 Deer of the Canadian Voyageurs, but there must be some 

 error in Mr. Warden's dimensions of the horns, which are 

 given as two feet long. In the United States the name of 

 American Roebuck is bestowed on it, and, in truth, there is 

 much resemblance in the two animals. We had an oppor- 

 tunity of drawing both sexes from a male and two females, 

 kept in the gardens of the Hospital at New York, where 

 we were informed that they came from Virginia.
