Chilian Guemal 369 



runs up the middle of the face from the muzzle to terminate in a fork 

 between the eyes ; the sides of the muzzle being brown, and the 

 extremity of the chin whitish. The upper surface of the tail is coloured 

 like the back, but the under surface is white ; there is no trace of the 

 brown patch on the rump and the brown upper surface of the root of the 

 tail characteristic of the Peruvian species. The under-parts and limbs, 

 with the exception of the inguinal region, the front and upper part of the 

 inner surface of the thighs, and a streak on the postero-internal surface of 

 the fore-legs (which are greyish white), are also coloured like the back ; 

 thus presenting a very striking difference from the Peruvian animal, in 

 which they are very much lighter. The tarsal tuft on the inner side of 

 the hock, instead ot being dark umber-brown on a whitish ground, is 

 likewise of the same speckled hue as the upper-parts. 



In regard to the antlers, they are distinguished trom those of the 

 Peruvian species by the forking taking place at a considerably greater 

 distance above the burr, so that between the latter and the upper surface 

 of the fork there is an interval of nearly 2 inches instead of less than 

 I inch. 



The antlers of the mounted specimen in the Museum, which came from 

 Patagonia, are comparatively thin and smooth. In a head trom Ultima 

 Esperanza, Patagonia, also in the Museum, which forms the subject of 

 Plate VII. Fig. 9, the antlers are, however, much stouter and more rugose, 

 perhaps indicating an older animal. Moreover, in that specimen the 

 seneral tone of the hair is grever and less rufous, while the black mark on 

 the face is narrower and less deep in colour. Now this specimen is said to 

 have been killed in }une, that is to say, in the middle ot the southern 

 winter. And it would accordingly seem that the guemals, like so many 

 deer, exhibit a reddish phase in summer, and a more greyish (blue) tint 

 in winter. 



The Chilian guemal was originally named trom specimens obtained in
