CHELONIA . 



Apparently nearly allied to the existing forms. The vertebral 

 shields are relatively wide, with acnte lateral angles ; the 3rd ver- 

 tebral embracing three neural bones. 



The identity of Emys Icevis with this species was first pointed out 

 by Eiitimeyer (Z. c). The skull provisionally referred by Owen to 

 this species is noticed under the heading of Pseudotrionycc. P. 

 indica, Lydekker x , differs from the present species by the narrower 

 vertebral shields, of which the 4th overlies four neural bones, as in 

 the existing P. sextuherculata (fig. 41).

The type specimen, which is figured by Owen in his 4 Reptilia of 

 the London^Clay fee./ vol. i. pi. xxiii., was formerly in Mr. Bower- 

 bank's collection, but since it was not sent to the Museum with 

 that collection it is probable that it must have perished through 

 pyritous decomposition.
