SNAKES OF THE PHILIPPINE ISLANDS 



subcaudals, 110 to 118; the range of ventrals is extended some- 

 what by the scale count of the described specimen. The scale 

 rows, 16 or 18 on middle of body. 



Remarks. — This species has only recently been found in Pa- 

 lawan and was first reported by Griffin. This is the only Phil- 

 ippine island where it has been found and there it is said to be 

 common. It grows to a length of more than 3 meters. Superfi- 

 cially it resembles Naja hannah Cantor in both size and mark- 

 ings. It is harmless. It is also known from Java, Sumatra, 

 Borneo, and the Malay Peninsula.

* Stejneger says: "The generic name Simotes, by which the snakes of 

 this genus have long been designated is preoccupied by Simotes of Fischer 

 for a group of mammals as early as 1817. It has consequently to be re- 

 placed. Cope proposed Hohircliiis, in 1887, as a term for those species of 

 the genus which have an undivided anal. It is not believed that this char- 

 acter alone, which moi-eover is not always constant, is sufficient ground for 

 a division of the g-enus, and as Hohur-lnis is the name next in date after 

 Simotcs it must stand for the combined genus."
