visionally referred to tlie same species. No other remains have been hitherto 
described. 
Present notice— In this memoir the two specimens mentioned above are de- 
scribed and figured, and a calcaneum and proximal phalangeal, different from those of 
any other sivatheroid, are provisionally ref erred to the species. No other parts of the 
skeleton have been yet determined. 
Upper molar. — In figure 2 of plate XXI of this volume the specimen of an 
upper true molar, noticed above, is figured ; it is the penultimate tooth of the left 
side, and is scarcely touched by wear ; the summit of the anterior ‘ lobe ’ has been 
somewhat damaged. The characteristic rugose structure of the enamel, and the 
large size of the specimen shows that it belongs to the present group of ruminants. 
The characteristic points of the tooth are the great height of the crown, the slight 
development of the median ‘ costa ’ on the anterior c lobe,’ and its complete absence 
on the posterior ‘ lobe.’ The latter points at once distinguish the tooth from the 
molars of Sivatherium. The teeth of Bramatherium , and most of those of Hydas- 
pitherium megacephalum differ in the greater development of the c costae,’ though 
some -varieties referred to the latter make an approach in this respect. The latter 
teeth have, however, relatively lower crowns, the dimensions being as follows : —

The absence of a e cingulum ’ distinguishes the tooth from the molars of Vishnu - 
therium. On the whole, it seems probable that the present and another similar 
tooth in the Indian Museum belong to a second species of Hydaspitherium for which 
the name 3. grande has been proposed. 
Mandible.— In plate XX of this memoir is figured the greater portion of the 
left ramus of the mandible of a sivatheroid, obtained by Mr. Theobald in the 
Siwaliks of the western Punjab, and provisionally referred by myself in the 
“ Records ” 1 to the present species. The following description is mainly copied 
from that notice. The specimen is broken off immediately behind the last true 
molar, and extends as far forwards as the commencement of the symphysis ; it 
shows the last premolar and the three true molars, the first and last teeth having only 
been in use for a short time. The ramus of the mandible differs from the one 
referred to 3. megaceplialum (plate XIX) by its much greater vertical depth, and 
by its outer surface being slightly concave, in place of markedly convex, in both of 
which respects it approaches the mandible of Sivatherium. The structure of the 
molars, however, at once distinguishes the specimen from the latter genus, as it
