122 CHELONIA. 



figs. 1, la, as B. cautleyi, of which it is the type. This 

 specimen, in which the sutures of the bones are not visible, 

 was specifically separated from the preceding on account 

 of its more depressed form ; but this feature is not regarded 

 by Boulenger (' Catalogue of Chelonians, &c.' p. 64) as of 

 any importance. Presented by Dr. Hugh Falconer. 



R. 598. Cast of a portion of the carapace of an immature individual. 

 The original was obtained from the Siwaliks of the Pun- 

 jab, and is preserved in the Indian Museum, Calcutta. 

 It is figured by the writer, op. cit. pi. xxv. fig. 1, as B. 

 falconeri. Made in the Museum, 1885. 



R. 890. The somewhat imperfect and crushed shell of an immature 

 individual ; from the Siwalik Hills. The nuchal is want- 

 ing, and the neurals and costals of the carapace are crushed 

 in, and in the posterior region much dislocated. The an- 

 terior lobe of the plastron is broken off, the ento- and 

 epiplastrals being preserved within the carapace. The 

 xiphiplastrals are imperfect. The 3rd and 4th neurals 

 have a strongly marked knob-like carina, as in the pre- 

 ceding l and following specimens. The contour of the 

 first three vertebral shields is well shown. 



Cautley Collection. 



R. 748. The imperfect shell of a male ; from the Siwaliks of Perim 

 {Pig.) Island, Gulf of Cambay. Figured by the writer in the 

 ' Quart. Journ. Geol. Soc' vol. xlii. pi. xv., as Clemmys 

 ivatsoni, of which it is the type ; the describer being then 

 unaware of the difference in the size of the sexes of the 

 present species. Presented by Col. J. W. Watson, 1886. 



R. 603. The imperfect shell of a male ; from Perim Island. This 

 specimen includes part of the middle region and right half 

 of the carapace and plastron. It has been polished and 

 worn by the action of water; but the boundaries of the 

 bones and of the first three vertebral shields are still 

 traceable.

R. 954. Part of the right half of a shell probably referable to a 

 male of this species; from Perim Island. This specimen

 cimen are incorrectly alluded to as the 4th and 5th.
