372 THE ZOOLOGIST. 
ON A NEW DEER, CARIACUS CLAVATUS, FROM CENTRAL 
AMERICA.* 
By Freperick W. TRUvE. 
In Messrs. Salvin and Godman’s ‘Biologia Centrali- 
Americana, Alston enumerates four species of Deer as 
inhabitants of the region between Texas and the Isthmus of 
Panama. ‘These are Cariacus macrotis (Say), C. virginianus 
(Boddaert), C. toltecus (Saussure), C. rufinus (Bourcier et 
Pucheran). Of these, the first three belong to the subgenus 
Cariacus, as defined by Sir Victor Brooke, and the fourth to 
the subgenus Coassus. 
It is now my intention to add to the list of Central American 
Deer a fifth species, which, as I shall presently show, presents a 
superficial resemblance to the species of the subgenus Coassus, 
but belongs in reality to the subgenus Cariacus. 
The description is based upon a good series of specimens in 
the National Museum, including young and adult individuals of 
both sexes. The species never acquires branched antlers, and I 
have therefore chosen for it the name of Cariacus clavatus. 
Description.—Stature medium ; antlers simple spikes, directed 
backwards nearly in the line of the face. In general appearance 
and colour like C. virginianus. A small metatarsal gland present. 
Hoofs yellowish at the extremity. 
Male, young, summer pelage.—General colour bright chestnut. 
Head greyer than the back. A white spot on each side of the 
yhinarium, succeeded by an oblique dusky brown band, which 
reaches from the nostril to the margin of the upper lip, and is 
continued by a spot on the margin of the lower lip. Behind the 
dusky band is one of whitish grey, which is merged into dark 
grey posteriorly. The latter colour is strongly tinged with 
chestnut on the cheeks, temples, and forehead. The median line 
of the face is occupied by a dusky brown band, which extends 
backwards nearly to the line of the eyes. The forehead is 
occupied by a broad crest of long reflexed hairs, which in the 
mass are darker than those of the face. The individual hairs 
are brownish grey at the base, darker near the tip, where this 
colour is succeeded by a ring of light yellow, more or less
