288 FAUNA ANTIQUA SIVALENSIS. 



No. 36. Bos ? — Fragment comprising facial part of cranium, 



like 35, but crushed laterally, presenting the two maxUlaries with the 

 whole series of molars in each. Nasals broken off by a fresh fracture 

 near commencement of diastema. The palate is broken from the 

 crushing, and the opposite lines of molars are at tmequal heights. 

 Length of left molar series, 5 "9. The molars are all protruded and in 

 the same state of wearing as in No. 35. The specimen is encrusted 

 with an argillaceous matrix. 



No. 41. Bos Namadicus. — Fine specimen of craniiim, nearly entire, 

 exhibiting the whole of the chevron region from near the vertex on the 

 right side, as far as the extremity of the nasals, which are broken off 

 at their tips ; also all the maxillary portion of the diastema, with a 

 portion of the right incisive; the two orbits nearly entire; the two zygo- 

 matic arches and temporal fossaj ; the four back molars on the right 

 side, and the five front molars on the left side, all protruded and worn 

 so as to show that the animal was frilly adult but not aged. Also the 

 whole of the lower surface of the cranium, from the diastema back 

 along the palate and spheno-palate region on to the occipital foramen. 

 The basi-sphenoid protuberances, occipital condyles, foramen magnum, 

 tympanic bullse, and glenoid cavity perfectly entire, with the auditory 

 foramen, right side, partially shown. Also the posterior and basal por- 

 tion of the occipital entire. 



Deficient only at the vertex, which is broken off obliquely from the 

 right angle downwards and forwards to the left, the fracture having re- 

 moved the left side of the occipital plane, the whole of the occipital 

 crest, and the cores of the two horns. On the left side the fractiu-e 

 encroaches upon the plane of the frontal, but on the right the base of 

 the core of horn is in situ, broken off vertically in a line with the 

 supra-auditory apophysis at the root of the jugum. Truncated in 

 front about the middle of the incisives ; the supra- and infra-orbital 

 foramen present on both sides. In all other respects the specimen is 

 singularly perfect, with the exception of the inferior border of the 

 right orbit, which is abraded. The form of the cranium in this speci- 

 men differs very notably from that of the Gour and Gayal and other 

 bisontine forms, recent or fossil, in its much greater elongation as 

 compared with the width, in the lesser prominence of the orbital 

 margin, and in the more slender proportions of the whole of the facial 

 and muzzle regions. In these respects it exhibits a considerable re- 

 semblance to the taurine division of Bos as represented by Bos primi- 

 genius. This is well shown in the form of the construction between 

 the base of the horn-cores and orbits, which is in a long curve. From 

 Jahnsee Ghat on the Nerbudda.^ 



Extreme length of specimen, 18 inches; from the broken margin of 

 vertex to commencement of the diastema, 16 inches; from ditto to 

 upper border of orbit, 6-^ inches; antero-posterior diameter of orbit, 

 3'3 inches ; transverse ditto, 25 inches ; length from anterior border 

 of orbit to commencement of diastema, 7"3 inches ; length from broken 

 border of vertex to the naso-lachrymal termination of the frontal, 10'5, 

 Length of truncated portion of muzzle in front of molars, 2'2 inches ;
