In both species we note the excess of the transverse over the antero- posterior diameter of the crown (carried to the greatest extent in the Indian species), the wavy cingulum, surrounding the inner half of the tooth; the simple valley and single crochet ; the direction of the median valley is the same in both species. [...] 1) we are enabled to see the forms of the cosh from the contiguous unbroken lobes of the two molars : on the anterior half of the second lobe there are three costae, of which the median is the highest ; the posterior and anterior costae are of nearly equal height, the posterior being the most prominent ; the anterior costa leads downwards into a kind of cingulum, bordering the anterior edge of the [...] The molars approach nearest in form to those of Camelopardalis, which they resemble in the obliquity of their position in the jaw, and in the prominence on the inner border of the crown of the postero-internal angles of the barrels : they, how- ever, differ from the molars of Camelopardalis by the presence of the cingulum, and by the presence of the large pointed tubercle at the entrance to the me [...] The depth of the present jaw at the second molar is half-an-inch greater than in Camelopardalis gircffa, but the jaw is of a more slender type than in the latter genus ; in C. giraffa, and C. sivalensis, the depth of the jaw at the second molar is equal to the length of the second molar plus the length of the hinder barrel of the first molar ; in the present specimen the corresponding tooth is one [...] The inner wall of the anterior barrel of the second molar is, unfortunately, the only portion of this surface of the teeth which remains complete ; in this portion the postero-internal angle forms the most prominent point on the inner border of the crown, while the antero-internal angle is the least prominent of the three ridges into which the side of the barrel is divided, precisely the same as i
