on its upper and lower sides. Like the small branches on the erect 

 part of the horn, they are not exactly similar on the two horns.

The metatarsus is without any glandular tuft on the outside. On 

 the inner side of the hock is a large rounded tuft of such hairs. The 

 fur consists of thick, elastic, tubular quills. The skull has a well- 

 marked, deep, triangular pit in front of the orbit, and well-deve- 

 loped canines in both sexes. The female is without horns. 



It has been suggested that, as I have only seen one specimen of 

 the male, the horns may be those of an individual monstrosity, and 

 not of the normal form ; but this I consider to be very doubtful. If 

 they are not quite of the normal form, it is clear they are not a mon- 

 strosity of the regularly forked horns of Furcifer.

In" 1849 the Earl of Derby received from his brother-in-law, from 

 the coast of Chili, an imperfect skin of a female, which he sent to 

 the British Museum. The fur was of a different colour from that of 

 the specimen described by MM. Gay and Gervais ; and, finding the 

 animal to agree in size, colour, and kind of fur with the Koebuck of 

 Europe, I described and figured it, in the ' Proceedings' of the Zoologi- 

 cal Society for that year, under the name of Capreolus leucotis ; and 

 in the ' Proceedings ' of the Society for the next year, and m my 

 ' Catalogue of the Two-hoofed Quadrupeds in the British Museum,' 

 p. 227, I regarded it as a species of Furcifer, under the name of F. 



"*Mr Whitely, junior, sent from Tinta, in South Peru, to the 

 British Museum a perfect male, female, and fawn of this species, 

 and some skulls of the female, which induced me to regard the Cervus 

 chilensis of Gay and my Capreolus leucotis as different stages of the 

 same species, as those then received agree with Gay's description oi 

 the Touno- animal in the Paris Museum and are m the yeUow state 

 of the fur but the female exhibits in the middle of the back some 

 of the dark fur of the animal (sent by the Earl of Derby) whidi I 

 described • but M. Philippi, in a recent paper above quoted, states 

 decidedly thnt the Cervus chilensis is a synonym of C. antisie^isis,
