A LIST OF SNAKES FOUND IN PALAWAN.

Two collections of snakes from Iwahig, Palawan, one made by Mr. 

 C. M. "Weber of Iwahig and the other by Mr. Sclmltze of this laborator]', 

 have recently been placed in my hands. As these collections add con- 

 siderably to the known Ophidian fauna of the island, it seems well to 

 publish a complete list of the snakes now known to be found in Palawan. 

 The only other considerable collection of snakes Imown to be from this 

 island was made about sixteen years ago by Mr. Everett and described 

 by Boulenger.^ 



In 1881 Peters ^ published the description of a snake from Palawan, 

 Doliophis biluieatuSj "the first poisonous snake recorded from the Phil- 

 ippines." Aside from these papers I do not know of any which treat 

 'of Palawan snakes. Cuming sent a number of snakes from the Philip- 

 pines to the British Museum,^ but since the locality is given as "Phil- 

 ippines" only, it is impossible to take them into account while listing 

 the snakes of any particular locality. 



Four new species are described in the following list; there is also 

 recorded one genus and three species already known from other localities 

 but now found for the first time in the Philippines. We now know 

 of thirty-one species of snakes which exist in Palawan. Thorough ex- 

 ploration of the island will undoubtedly add many more species to the 

 list, especially of marine forms. Fourteen species are added to Boul- 

 enger's list, and all tend to confirm his conclusion as to the close relation- 

 ship of the Palawan reptiles with those of Borneo. 



The species included in Webei*'s collection are indicated by an asterisk 

 (*) after the name; those in Schultze's collection by a dagger (f) ; and 

 those in Everett's collection, listed by Boulenger, by a double dagger (t).
