274 FAUNA ANTIQUA SIVALENSIS. 



is thick, and there is a very rapid contraction immediately below the 

 verteljral foramen, which is situated high up on either side ; the 

 median ridge along the under side of the body is in great relief and 

 thick and prominent at its extremity. The form of the body differs from 

 that of all other ruminants in the great divergence and spread of the 

 posterior continuation of the inferior transverse processes, which ter- 

 minate in a thick projecting mass, instead of being inflected downwards 

 and inwards as in the bovine ruminantia; the spinous process also 

 differs remarkably, inasmuch as it appears to have been a short thick 

 mass instead of a leafy expansion, as in most other ruminants. The 

 inferior articulating surface is partly concealed by matrix, but it appears 

 to be oblique and deep ; the posterior oblique processes are broad and 

 flat. The length of the superior vertebi-al laminse is short as compared 

 with other ruminants. The projecting edge of the odontoid process is 

 slightly broken off. In the aggregate of its characters, the axis of the 

 Sivatherium is remarkable for shortness and thickness.

Found with specimen No. 329, and presented by Conductor Dawe, 

 See Jom-n. As. Soc. iv. 506, PI. XLIV. fig. 1, 



No. 332. — Specimen of cervical vertebra, pi-obably the fourth, 

 more mutilated than the axis. The anterior and jiosterior articu- 

 lating surfaces of the body present, as also the two posterior 

 oblique articulating surfaces ; the anterior oblique articulating pro- 

 cess on the right side' is partly shown, on the left broken off at its 

 base, as also the spinous process ; on the left side a part of the superior 

 and inferior transverse processes (Owen) is shown ; on the right they 

 are broken off close to their base. A good deal of matrix remains on 

 the fossil, concealing some of the parts. The anterior articulating head 

 of the body is ovate in its outline as in the ox, but more vertical in its 

 direction. The posterior articulating cup is very deep. The posterior 

 oblique articulating processes are very broad. Vertebral foramina 

 large with a short canal. The bone is too much mutilated to afford 

 dimensions, but corresponds in dimensions with the axis, and was found 

 in the same place adhering to the large antler No. 329. All three 

 probably belong to the same animal. — Journ. As. Soc. vol. iv. p. 506,

■■&• 



No. 333. — Sixth cervical vertebra, showing the anterior and posterior 

 articulating surfaces, the former nearly entire ; the bases of the anterior 

 and posterior oblique processes present, but the articulating surfaces 

 broken off, as also the spinoiis and transverse processes. Vertebral 

 foramen is present, on left side, of enormous size, with an exceedingly 

 short canal.
