 reports it from southern Mindanao, and a specimen was recently 

 taken in northern Kalinga, Luzon. f 



CORONELLIN^E 



Hypapophyses absent on the posterior dorsal vertebrce, the 

 lower surfaces of which are smooth. All maxillary teeth solid, 

 none grooved. Scales imbricating, ventrals enlarged trans- 

 versely. Nonpoisonous. 



A large number of genera belong to this family. They occur 

 in all temperate and tropical parts of the world. Fifteen genera 

 are recognized in the Philippines.
