and there is a distinct notch between the supracaudals; there is 
a small notch in the plastron between the anals. The very im- 
portant character of the posterior serrations on the carapace 
suggests a distinct geographic race. The locality from which 
the specimens came is unknown. 
Remarks.—Turtles of this species are fairly common in the 
Philippine Islands or at least are frequently seen, because they 
are often kept as pets. The adults are often found at a con- 
siderable distance from water; the young, however, are aquatic. 
The species is known from Luzon, Polillo, Dinagat, and Min- 
danao. It ranges from southeastern Asia through the Malay 
Archipelago to Celebes and Amboina. The name for the species 
in the Visayan dialects is bao.

* Stejneger is of the opinion that the name dentata should be retained 
rather than dhor, see Mem. Mus. Comp. Zool. 44 (1912) 143. Gray 
his later work, chose dhor as the name for retention.
