For the most part the genei-a that do occur are widely dis- 

 tributed in the Philippines. Thus of the thirty-three terrestrial 

 and arboreal forms, seven have not been taken in Luzon nor, with 

 two exceptions, in the Visayan Islands. These are Xenopeltis, 

 Dnjocalamus, Sibijnoi^his, Oligodon-, Liopeltis, Typhlogeophis, 

 and Hajylopeltura. 



Oligodon has been taken in Negros, and Liopeltis in Samar 

 and in l^eyie. These two also occur in the Palawan group
