Horns broad at the base, inclining more or less downwards and 

 outwards, and then bent upwards. 

 Hab. Africa. 



C. gnu. C. taurina. 



The next genus is included by Mr. Gray among his "Caprine 

 Antelopes," but differs from them in having a suborbital sinus or 

 gland, of large size in some species, and of peculiar structure, opening 

 externally by a single pore. Their nasal bones resemble those of the 

 domestic Sheep, and their structure being altogether rather heavy, 

 they might be called Ovine Antelopes. 



Nemorhjedus. 



No suborbital fissure ; the fossa rounded, shallow, very variable in 

 size, sometimes very minute ; the nasal bones rather short and broad, 

 joining the maxillaries only by the interposition of some imperfect 

 ossification or separated from them altogether ; the masseteric ridge 

 extending high before the orbit ; the auditory bulla very small ; the 

 basioccipital bone broad, with moderately developed eminences ; the 

 middle incisors slightly expanded at their summits ; the molars 

 without supplemental lobes. 



Horns rising behind the orbits, annulated and wrinkled at the base, 

 inclined and curved backwards. 



Hab. India and its islands. 



C. bubalina. C. Sumatrensis. C. goral. 



This genus is too well-marked by nature to admit of subdivision. 

 Although the " tear-bag " is said to be wanting in the Goral, there 

 is certainly a slight depression upon the lacrymal bone, and the pore 

 with which the gland opens may be so small in this species as to 

 escape detection in dried specimens ; but if it be really absent, the 

 instances of the genera Gazella and Ovis must warn us against found- 

 ing a genus solely on the want of this organ, while on the other hand, 

 a difference in its structure seems to be of great zoological import- 

 ance. 



Since the foregoing observations were written, I have perused Mr. 

 B. H. Hodgson's interesting account of the Budorcas taxicolor, in 

 the ' Journal of the Asiatic Society of Bengal,' and a glance at the 

 representations of the skull indicates very plainly that it is closely 

 allied to Nemorhtedus, to which Mr. Hodgson admits certain resem- 

 blances, and that it has no relationship with the Gnu, or the Musk 

 Ox. The characters that I assigned to Nemorhcedus would appear 

 to serve as well for this new and singular genus, except that there 

 seems to be no suborbital depression, and the masseteric ridge, as 

 may be expected from the general elevation of the skull, does not rise 

 before the orbit. The horns, whose peculiar twist must constitute the 

 diagnosis of the genus Budorcas, appear, from the rough figures 

 given, to have the wrinkling at the base very similar to that in Ne- 

 morhcedus. 



The following genera may be considered as in some degree allied, 

 and deserve the name of Caprine Antelopes. They have no sub-
