NEW DEER FROM CENTRAL AMERICA. 379 
This antler certainly does not belong to our C. clavatus, but 
appears to be a dag-antler of the Virginia Deer, of which we 
have many in the collection. 
Our species differs from Cariacus yucatanensis (Hays) (= C. 
acapulcensis, Caton), in the presence of a metatarsal gland, and 
in the size and form of its antlers. The latter species, according 
to Mr. Hays, does not change its colour, which is not true of C. 
clavatus. ‘There is in the collection of the National Museum a 
male Deer labelled C. gymnotus, which was presented by the 
Zoological Society of Philadelphia, and was supposed to have 
been derived from South America. It is not clearly distinguish- 
able from C. yucatanensis, and also agrees in colour with the grey 
form of our C. clavatus. From the latter, however, it is distin- 
guished by the absence of a metatarsal gland, and by its forked 
antlers. It is also much darker on the face and back, while the 
insides of the legs are whiter. The hairs surrounding the tarsal 
gland are white, and the hair posterior to the navel has the points 
directed backwards, while in C. clavatus they are directed forwards. 
The hoofs are black throughout in this specimen, but in C. 
clavatus they are yellow horn-colour at the extremity. 
It seems to me improbable that Cariacus toltecus (Saussure) is 
identical with C. yucatanensis, but rather with C. sartorit (Sauss.) 
(=Coassus rufinus, B. & P.). At all events none of these 
nominal species appear to have any close relationship to our 
C. clavatus. 
From the specimens in the National Museum it appears that 
the range of C. clavatus extends at least from the province of 
Tehuantepec, in Mexico, to Costa Rica; but its presence in 
Yucatan, British Honduras, and Nicaragua has not been ascer- 
tained. There are no specimens from the Pacific Coast of Central 
America, and it is improbable that the species occurs there.
