CRANIA OR RUMINANTS RROM THE INDIAN TERTIARIES. 83—170 
The parietals are of considerable length; between the horn-cores and the 
occiput they are rounded superiorly and excavated laterally by the temporal fossae ; 
the occipital surface forms an obtuse angle with the plane of the parietals, and 
its transverse diameter is greater than its vertical diameter ; the basioccipital is 
obscured by matrix ; the orbit is situated immediately below the horn-cores, and the 
two are separated by a considerable interval. There is a small supra-orbital fora- 
men, but no sinus ; the horn- cores are placed very closely together at their base, 
and curve upwards and backwards, with an extremely slight outward direction : they 
diminish very rapidly in width, and their antero-posterior diameter is very much 
greater than their transverse ‘diameter ; their cross-section is somewhat triangular, 
presenting sharp ridges at their two internal angles, and a third ridge at the hinder 
haR of their outer surfaces. The measurements of the specimen are as follows : —

The cranium of this species is distinguished from the crania of the small-horned 
females of Capra sibirica, and Capra cegagros by the horn-cores being so much 
more closely approximated at their bases, by their being very slightly inclined out- 
wards, and by their thickness at the base. 
Among the living goats the cranium of this species approaches nearest to that 
of Hemitragus hylocrinus of the Nilghiris ; the horn-cores of both species have 
nearly the same position and direction ; those of the living species, however, are 
placed shghtly wider apart at their bases, form a rather more open curve, and have 
a nearly flat surface in front : the distance also between the horn-core and the orbit 
is somewhat less than in the fossil species, and the parietals are flatter and less 
rounded superiorly. It is, however, quite possible that the recent and fossil forms 
should be placed in the same genus.

The specimen on which this species is founded is from the collection of the 
Asiatic Society of Bengal ; it was obtained from Perim Island by Captain Eulljames, 
and was entered in the Catalogue of the Society’s Collection (No. as the 
cranium of a species of antelope by Dr. Ealconer ; to this genus it cannot belong, 
as is at once shown by the form of the horn-cores, which have a keel on both 
anterior and posterior borders, and a very long antero-posterior diameter, conditions 
which are found in no antelopes, and which are characteristic of the goats. 
The specimen comprises a portion of the frontals and parietals, with the nearly 
complete horn-cores of both sides ; the portions of the frontals remaining are convex
