HEMIBUNGARUS 269 



appear to be rather rare in the PhiHppines. The name oro-odto 

 (Bohol-Visayan) is applied to this snake. It is probable that 

 the names camamalo and palapcd are also referable to this species.

Remarks. — I have seen no specimen of this snake. Obviously 

 it is very rare, and none appears to have been taken in recent 

 years. The only definite locality known is Manila, recorded by 

 Jan. Only a few specim.ens are known. The species is deadly 

 poisonous.
