bone with the posterior tubercles moderately developed, the anterior 
ones scarcely at all; the molars with supplemental lobes. 
Horns short, round, vertical, slightly bent forwards. 
Hab. India. 
P. picta.—The only skull that I have seen (that in the British 
Museum) wants the incisor teeth, so that I could not ascertain their 
structure. The smooth line upon the lacrymal bone terminates in a 
small foramen, but on one side is continued for some distance for- 
wards upon the maxillary bone, where it terminates in the same way; 
and it may even be faintly traced on the other side for some distance 
beyond the foramen. 
CapRA. 
A small suborbital fissure, no fossa ; the masseteric ridge ascending 
high before the orbit ; the auditory bulla prominent and compressed ; 
the basioccipital flat, with its processes developed ; the middle incisors 
not expanded ; the molars without supplemental lobes. 
Horns erect, compressed ; curved backwards and a little outwards, 
or twisted; annulated or nodulous, and furnished with one or more 
longitudinal ridges. 
Hab. The Northern portions of the Old World. 
C. hircus. C. Falconeri. 
C. ibex. C. jemlaica. 
I do not see sufficient reason for separating the Jemlah Goat, as 
has been done, under the names of emicapra and Hemitragus. 
Ovis. 
A more or less marked, rounded, suborbital depression, but no 
fissure ; the masseteric ridge ascending high before the orbit ; the 
auditory bulla small; the basioccipital flat, more or less expanded 
anteriorly by the extension of the anterior pair of tubercles, the pos- 
terior ones small ; the incisors nearly equal-sized, sloping ; the molars 
without supplemental lobes. 
Horns broad at the base, transversely wrinkled, bent outwards, with 
a more or less marked spiral curve in a direction contrary to that 
occurring among the Antelopes, and a longitudinal ridge or angle. 
Hab. The Northern hemisphere. 
O. ammon. O. nahura. 
O. Vignei. . O. tragelaphus. 
O. aries. 
It is a matter of surprise to me that naturalists should almost uni- 
versally have given zo suborbital sinus, as characteristic of the genus 
Ovis, since it is very perceptible in the Domestic Sheep ; and in some 
other species, especially the O. ammon, judging by the appearance of 
the stuffed specimens, and by the fossa upon the skull, it must be of 
very considerable size. Ido not perceive it, however, in the O. trag- 
elaphus, nor in the O. nahura. Although Mr. Gray maintains the 
long-established error, the observations of Mr. Ogilby and Mr. Hodg-
