Yucatan Race 263 



The specimens which must be regarded as the actual types are those 

 described by Lichtenstein, and preseryed in the Museum at Berlin, since 

 Gmelin's C. mexicanus is a medley. On this point Mr. Rhoads observes 

 that the Ceruus mexicanus of Gmelin is based on the teuthlalmacame of 

 Hernandez's History of Mexico (1651). The description of the latter does 

 not apply to the prong-buck, as asserted by Berlandier, 1 and repeated by- 

 Alston. Hernandez's figure of the teuthlalmacame, whether intended for 

 the deer or prong-buck (it partly fits both), cannot affect the description, 

 which applies to the deer.

Characters. — Size very small, apparently about one-third less than that 

 of mexicana, but the tail relatively longer than in the latter. Antlers short, 

 upright, nearly straight, and semi-palmate, with but little forward projection 

 of the lower prong of the main fork, and the number of tines reduced. 

 Metatarsal gland and tuft wanting. General colour of upper-parts dark 

 chestnut-brown ; face blackish ; under-parts white ; tail, which is truncated 

 at the tip, brown above and white beneath. No seasonal colour-change. 



The aborted antlers (figured on page 224 of Mr. Caton's book) and the 

 want of the metatarsal tuft might be considered as sufficient evidence to 

 raise this form — the acapulco deer of Mr. Caton — to the rank of a distinct
