162 Dr. J. E. Gray on the Deer of 



with M. Gay's figure of the skull of the animal on which he 

 established Cervus chilensis, I have confirmed my former opinion 

 expressed in the 'Annals,' 1873, xi. p. 309, and have very 

 little doubt that it was described from a very young specimen of 

 this species. The figure exhibits the triangular preorbital 

 pit peculiar to the species, though it does not appear so deep 

 as in our specimens ; and the conical prominences on the sides 

 of the forehead, which are found in the two skulls of this species 

 in the British Museum, are well represented. Both the adult 

 skulls have the hole on the side of the lower jaw in the centre 

 of the diastema ; but in M. Gay's figure of the young skull it 

 is much nearer the front end of the jaw. The skulls of the 

 males and females have small, slender canine teeth. 



The very young animal figured by M. Gay is darker than 

 those brought by Mr. Whitely, and appears to be in its 

 summer coat. One of Mr. Whitely 's specimens, which appears 

 to be changing its fur, has some patches of hair of this dark 

 colour. 



It is quite clear that, even if the horns of the male brought 

 home by Mr. Whitely are not of the normal form, they must 

 be quite different from those of the much larger Huamela leu- 

 cotis from Magellan's Straits. 



As M. Gay's specimen was first described, I adopt his specific 

 name, and thus avoid the inconvenience that might result 

 should^he horns I have described prove to be malformations 

 and not the usual horns of the species, although I lay myself 

 open to the objection of the purist that I use the name chilensis 

 for a Peruvian species. 



Huamela leucotis from Magellan's Straits is at once known 

 from this species by its very much larger size : the animal 

 belongs to a larger type ; and the horns are peculiar. The 

 skull of Huamela has the large, very deep, subtriangular 

 tearpit of Xenelaphus ; the upper outer edge of the orbit 

 is thickened and produced behind into a conical prominence 

 on the side of the forehead, somewhat as in Xenelaphus, but 

 in a much greater degree ; and the intermaxillary bones are 

 broad behind, and reach up to the nasals. The skulls of the 

 males and females are destitute of canine teeth. 



2. Furcifer antisiensis. 



The skull of the female, which has been received from Mr. 

 Whitely, is very like the skull in the British Museum received 

 from the Zoological Society's museum under the name of 

 Cervus antisiensis, a species that is only known from a figure 

 of the animal by M. d'Orbigny, the skull of which has not been 

 described or figured.
