SNAKES AND LIZARDS KNOWN FROM NEGROS, WITH DESCRIP- 

 TIONS OF NEW SPECIES AND NEW SUBSPECIES 



By Edward H. Taylor 



(From the Section of Fisheries, Biological Laboratory, Bureau of Science, 



Manila) 



TWO PtATES AND TWO TEXT FIGURES 



This paper is based for the most part on collections made by 

 myself in Occidental Negros, P. I. Two principal localities are 

 represented : one is Isabela and the near-by mountains ; the other, 

 Mount Canlaon, or Malaspina, a volcano rising to a height of 

 2,461 meters in the north-central part of the island. 



The most fertile field for collecting was on Canlaon Volcano at 

 from 600 to 1,000 meters' elevation. Four trips were made to 

 this mountain, and many specimens were taken. The mountain 

 receives much rainfall during a large part of the year, and for 

 the most part the collecting was done in a heavy downpour. 

 Few places can boast of more mosquitoes. Two new species and 

 three new subspecies of snakes and three new species and one 

 new subspecies of lizards were collected. Many of the known 

 species found exhibited marked variations from the lowland 

 forms; this was especially noticeable in Sphenomorphus steerei 

 and Sphenomorphus jagori. Most specimens, of both snakes and 

 lizards, were noticeably colored on the ventral surface with can- 

 ary yellow, a color that is usually wanting on the same species 

 living in the lowlands. 



The number of new and unusual species taken leads me to 

 believe that when the mountain is thoroughly explored many 

 other new species will be found.
