formed horns of that animal ; but both tlic honis arc alike and have 

 the same peculiarities, which is not usual in malformations ; under 

 these circumstances it appears better to regard them provisionally as 

 belonging to a distinct species, to be established or erased from the 

 list as further knowledge may decide. 



There can be no doubt of the position of the horns, as a part of the 

 upper surface of the orbit is to be observed, with the remains of 

 the eyelids and eyebrows, at the base of the left horn. 



In the Cabrit, or AntUocapra americcina, the horns are thick, 

 rounded on each edge and produced into a compressed submechan 

 frontal process, which is gradually bent towards the inner side. 

 The tips of the horns are rounded, becoming nearly cyhndrical, and 

 are gradually and regularly arched backwards and inwards, with a 

 bluntish extreme end. 



The horns of the genus are peculiar for being lined internally with 

 a close velvety coat of short hair, directed towards the tip of the 

 cavitj' ; and the whole outer surface of the horn appears to be formed 

 of agglutinated hair, some separate hairs being seen on the surface. 



The peculiarity in the internal structure of the substance of the 

 horns of this genus shows, like the branched external form, a 

 similarity to the horns of the Deer, the hairy horn being the ana- 

 logue of the deciduous velvet of the Deer and the permanent hairy 

 coat of the Gu'affe. The ring of hair round the base of the outer 

 surface is to be observed equally developed in the horn from Lord 

 Derby's collection and in that of the common Pronijhuch. (Gray, 

 Anu. & Mag. N. Hist. 1856, vol. xra. p. 424 ; V. Z. S. Jan. 9, 1855.) 



SivATnERiiDiE. — Frontal bone with a central conical horn, and two 

 lateral horns over the orbit, which is dilated and branched on the 

 inner side ; nasal opening very large, like Elk. (Murie, Geol. Mag. 

 1871,vol.viii.p. 438.)

Suborder III. DEVEXA. 



Front of upper jaw callous, tootlilcss. Horns far behind 

 the orbits, permanent, on the coronal suture, between the 

 frontal and parietal bones, covered '\\itli a permanent liairy 

 skin, ending in a tuft of hairs. False hoofs none ; inter- 

 maxillarics moderate, reaching to the nasals.

The horn (dennocenis) is covered with a skin like the rest of 

 the body and equally permanent, and with hair that is shed 

 and renewed like the hair of the body, and ends in a tuft of hair. 

 The false hoofs wanting. The intermaxillary bones of the skull 

 moderate, reaching to the nasal. Muzzle hairy : lips rather elongate. 

 very flexible ; tongue very long, prehensile.
