144 DR. J. ANDERSON ON MANOURIA AND SCAPIA. [Feb. 6, 



concave from before backwards. The zygomatic arch is thin and 

 rather deep, but the depth is apparently variable ; for one side of the 

 skull (the left) is nearly 1'" less than the other, which is 5'". The 

 external nares are truncately triangular, almost quadrangular; the 

 premaxillary anterior margin is directed downwards and slightly 

 backwards. The other characters I shall borrow from Dr. Gray's 

 description of his genus Scapia : — " The groove on the palate very 

 deep and wide. The upper jaw with three narrow ridges — one on 

 each side of the margin, and a short thinner one intermediate between 

 them ; the outer margin high and without any teeth. Lower jaw 

 with a sharp edge, a rather acute sharp edge in the front part, and 

 with a sharp inner ridge rather more than half the length of the side, 

 separated from the outer edge by a deep groove."

This species of Tortoise has evidently a very wide range, extend- 

 ing from Assam, through Cachar, Arakan, and the moist regions of 

 Burmah, through the Malayan peninsula as far east as Java, extend- 

 ing to Sumatra, and doubtless to other islands, and, if the locality 

 Australia, given by Dr. Gray for a specimen in the British Museum 

 be correct, spreading to the south-east as far as that continent.
