to a female or immature male of this form. The absence 

 of the ventral carina is well shown. Cauiley Collection. 



16693. The produced portion of similar epiplastrals.

R. 927. The anterior extremity of a plastron referable to the same 

 form as the two preceding specimens. The epiplastrals 

 are nearly entire. Presented by Dr. Hugh Falconer, 1845. 



R. 929. The imperfect anterior extremity of a plastron not impro- 

 bably referable to this form. The produced extremities 

 of the epiplastrals are wanting, but on the ventral aspect 

 the area occupied by the posterior portion of the gular 

 shields is similar to that of the last specimen.

17968. An entoplastral and portions of the adjacent bones, not im- 

 probably referable to this species. Cauiley Collection. 



R. 882. The anterior portion of a nuchal bone, which agrees fairly 

 well in relative size with the above-mentioned epiplastrals, 

 and may therefore be referable to the same species. This 

 specimen shows the area occupied by a large and elongate 

 nuchal shield, and, thereby, indicates a different species 

 from the nuchal referred to T. atlas. The length of the 

 anterior border is nearly the same as in the latter. It 

 would of course equally indicate the existence of two 

 large Siwalik tortoises if the present specimen belonged 

 to T. atlas and the above-mentioned nuchal to the present 

 form ; but the massiveness of the latter bone favours 

 Falconer's reference. Cauiley Collection. 



Testudo, sp. 



The undermentioned cranium indicates a tortoise of considerably 

 larger size than T. elephantina, and allied in cranial structure 

 to the tortoises of the Mascarene and Galapagos Islands. It cannot 

 be determined whether this specimen should be referred to the pre- 

 ceding form or to a large individual of T. cauiley i. It is clearly 

 quite different from the cranium No. 39819 mentioned under the 

 head of T. atlas.
