36673. The cranium of a hornless and probably female form ; from 

 the Pliocene of the Siwalik Hills. This and the following 

 specimen may be specifically identical with one or other of 

 the foregoing species of Siwalik Antelopes. 



Presented by the Secretary of State for India, 1860. 



39569. The cranium of another, and apparently different, hornless 

 form ; from the Pliocene of the Siwalik Hilla. 



Presented by Dr. Hugh Falconer. 



Species 3. (Antilope clavata, P. Gervais 1 ). 

 Syn. Antilope sansaniensis, Lartet 2 .

Family GIRAFFID^E. 



Syn. Camelopardalidce. 



In this family, which is taken to include the Sivatheriida;, the 

 cranial appendages, when present, appear intermediate in character 

 between those of the Bovidce and Cervidce. The teeth are always 

 invested with a rugose enamel. 



Dentition : I. ?, C. ?, Pm. |, M. |. 



Genus SIVATHERIUM, Falconer and Cautley 3 . 



By some writers this genus is considered to be more closely allied 

 to the Antelopes than to the Giraffes ; but the kindred Indian 

 genera, Hydaspitherium and Vishnutherium, appear to have decided 

 giraffoid characters, which also occur in the limb-bones of the 

 present genus. There are two pairs of cranial appendages, the 

 bases of each being separate. The anterior pair are conical, like 

 those of the Giraffe ; while the posterior are palmate and resemble 

 the antlers of the Elk. There is no lachrymal vacuity in the
