76 CHELONIA. 



from T. elephantina. In Falconer's restoration of the 

 carapace these bones are placed at a considerable interval 

 from the nuchal bone, as if there were some four preaxillary 

 marginals, thus making the carapace much too large. 

 The anterior border of the first marginal is imperfect. 



Cautley Collection. Presented, 1840. 



16903 a. Part of the left side of the shell. This specimen, which 

 belongs to the same individual as the preceding, shows 

 the axillary notch, and a considerable portion of the 

 plastron and carapace in the neighbourhood of the bridge.

16909. The 1st marginal bone of the left side, with the antero- 

 internal angle broken away. A small fragment of the 

 2nd marginal is attached to the postero-internal angle. 

 The whole of the free border is entire. 



Cautley Collection. 



16904. The posterior portion of the 2nd and the nearly entire 3rd 

 marginal of the left side. This and the preceding speci- 

 men present all the characters of the above-mentioned 

 marginals and are therefore provisionally referred to the 

 same species. The axillary buttress of the hyoplastral is 

 well displayed on the inner surface of the 3rd marginal, 

 and extending superiorly on to the 2nd.

R. 326 C. The imperfect 7th and 8th marginals of the left side. 

 Types. In Falconer's restoration this specimen is 

 separated by a long interval from the next, instead of 

 being separated by the width of only one marginal. 



Transferred from the Indian Museum, 1880. 



R. 326 b. The posterior extremity of the carapace. One of the 

 types. This specimen comprises the pygal, and portions 

 of the 11th and 10th marginals, although the sutures 

 between these bones are not exhibited. Nearly the whole 

 of the area occupied by the caudal shields is shown, the 

 division between the two being clearly indicated. 



Transferred from the Indian Museum, 1880. 



16897. The right inguinal region of the carapace. One of the 

 types. Includes nearly the whole of the 7th and 8th 

 marginals, and the anterior extremity of the 9th. The
