(the intermaxillaries not reaching the bones of the nose at all) is ample ; 

 and this, with the convexity of those bones, leaves abundant space for the 

 olfactory apparatus. Other peculiarities of this scull, are, that the rami 

 of the lower jaws are but slightly bent in comparison to those of Bos ; 

 and that their condyles as well as those of the foramen magnum have a 

 lower than ordinary position. The horns, of very moderate length, and 

 gradually attenuated from a very thick base, occupy the extreme ends 

 of the frontal crest, filling its breadth but not ascending within two inches 

 of its greatest height. Their direction is towards the sides with a slight 

 uniform ascending and retiring curve, which brings the points back about 

 half way to the bases with a direction suited to their junction over the 

 neck, though, in males especially, the distance between the points always 

 remains great. The horns are upon the whole rounded, but with consi- 

 derable oblique depression towards the massive bases, so that their breadth 

 is greater by § than their depth, and the anterior surface sharper or 

 narrower than the posterior one, the greatest surfaces being (in a hori- 

 zontal position of the scull) towards the zenith and nadir. The result 

 is a subtrigonal or ovoid section at the base, where in old animals there 

 are externally several heavy wrinkles : the colour is horn green with 

 black tips. 



No. 2, which is the half reclaimed stock of Gavceus vel Bos sylhetanus, 

 is likewise a large scull, not above a 6th less than the preceding in 

 dimensions of extent, but scarcely exceeding half of the weight of it, the 

 bones being far less massive and also smooth on the surface. Here again 

 we have signal length and breadth in the frontal region, both rapidly 

 diminishing in the relatively contracted facial, so that the distance 

 between the small fine muzzle and the eyes exceeds not that between 

 the latter point and the summit of the head. In the precedent scull, 

 the same proportion was observed. But in the profile of the pre- 

 sent there are none of the curved lines, so noticeable in the last 

 — no frontal crest, no saliency in the orbits, and no arcuation in the 

 length of the nasals, which are, besides, as well comparatively as posi- 

 tively short, whence the interval, between their points, and those of 

 the intermaxillaries is much greater than in the last ; though, as in it, 

 these bones are entirely disconnected by the intervention of the 

 malars. The greatest width of the frontals, at the two points before 

 indicated, is to their length as 13 and 10 to 8|. These are dimensions 

 and proportions pretty similar to the last, and exhibit a comparative 

 breadth not found in the common types of Bos, with which however the 

 present scull agrees in the perfect flatness and rectilinearity of its frontals,
