DR. J. E. GRAY ON THE TRIONYCHID.E. 



[Jan. 7, 



The skull only is known, which probably belongs to Trionyx hurum, 

 as it seems to come from a large species not uncommon in India, as 

 is the case with T. hurum. 



There is a second specimen of this skull, which was given to the 

 British Museum by Mr. Theobald as the skull of his Trionyx phayrei. 

 It certainly was not the skull of the species which he described under 

 that name in the • Journal of the Linnean Society,' and not that of 

 the tortoise described under that name by Dr. Anderson. 



5. Trionyx sewaare. (Fig. 4.) 



The upper surface of the head uniform olive, with a distinct yel- 

 low spot on each side of the crown.
