 Texas (Lord Derby) ; Cayenne (Buffon) ; Guiana (Schonihurcjk) ; 

 Honduras ; Santa Fe de Bogota. 



In T>ichtenstein's work the figures of the horns look rather larger 

 than the specimens wc have in the Museum ; but it is to be observed 

 they scarcel}^ exceed the length of the head, and are described as 

 5| inches long. The ears are not more naked than the other species. 



There is a pair of horns verj^ similar to the series from Mexico 

 and Costa Rica, but differing in the beam being more elongated and 

 arched forward in front. 



Ham. Smith identifies his Deer with the liorns from Cayenne 

 figured by Cuvier, and with a specimen from Cayenne and Hon- 

 duras, but the haimches are represented too white. 



There is a skull in the Museum (52, 12, 26, 160) which evi- 

 dently belongs to this group, with horns much more slender, but 

 otherwise similar ; and the skuU is much jiarrower for its length, 

 and has the preorbital pit oblong triangular at the base, instead of 

 nearly circular. It was received from the Zoological Society in 

 1852 as having come from S. America. It also differs considerably in 

 having the hinder openings to the nostrils much narrower and the 

 palate stronglj' keeled in front of thom, which is not found in the 

 other skull from Mexico. It may be distinguished as Cariacus 

 ' lejjtoceplialus). 



12. EUCEEVUS. 



Horns rather curved forwards and outwards ; subbasal snag on 

 the inner side, but some distance above the base ; median snag ante- 

 rior, furcate ; upper snag posterior, making the antlers bifurcate, 

 iletatarsal gland large, elongate. Hoofs rather elongate. Tail hairy 

 beneath. (Gray, Ann. k Mag. N. H. 1866 ; Cat. Ungul. B. M. t. 34. 

 f. 4, as Cariacus.) 



Cervus, Section C, Spencer Baird, Mam. N. A. 637, figs. 19-22. 



Horns like those of BlaMocercus, but curved, and generally with 

 a subbasal snag. 



Euccrvus is characterized by the horns being doubly forked, the
