1618 a. Skull of a rather young animal, with only five grinders on 

 each side, which yet appear to be fully formed, and is unlike 

 the skull of any South- American deer in the Museum Collection, 

 the brain-cavity being much larger and more ventricose com- 

 pared with the compressed face than in any other known skuU ; 

 and it has rudimentary canines, which are not to be obsers^ed in 

 any species of Coassus or smaller South- American deer. The 

 skull is 6f inches long, and 3^ inches wide in the lower edge of 

 the middle of the orbital opening (which is the widest part of 

 the skull), and 3f inches fi'om the end of the occiput to the front 

 of the orbit, and 3| inches fi'om the front of the orbit to the end 

 of the interruaxillaries. There is a rather elongate groove over 

 each orbit, as in the skull of Coassus nemorivagus ; but the 

 brain-case of this skull is very much narrower, and has a keel in 

 the centre of the forehead, which is enthely absent in the flat 

 broad forehead of Cervus Whitelyi. There is a moderately deep, 

 concave, rounded pit for the tear-gland, and two perforations 

 for the passage of vessels tln^ough the orbit, just behind the 

 lachrymal pit. The brain-case is oblong, narrowed above, at 

 the upper edge of the orbits. At the lower edge of the orbits it 

 is much expanded out, being the widest part of the skull. The 

 face, fi-om the upper edge of the orbits, is graduallj'-, and from 

 the lower edge of the orbits rapidly, attenuated as far as the 

 front end of the grinders. The nose, from the front end of the 

 grinders, slender, compressed, with the front half of its length 

 rather narrowed on the sides. The nasal bones moderate, the 

 middle of the hinder end being broadly produced between the 

 front of the fi-ontals, which I have not observed in any other 

 deer. The intermaxillary bones very slender in front, the hinder 

 half becoming much broader above, and attached to the sides of 

 the front of the nasals — more so than in any South- American 

 deer that I have yet observed. (PI. xxxii. f. 2).
