xu,D, 6 Taylor: Snakes and Lizards of Negros . 359 



Cyclocorus lineatus Reinhardt. 



More than twenty specimens were captured on the volcano; 

 many others seen were not taken. A single young specimen 

 killed by Mr. McNamara is the only specimen obtained from the 

 lowlands. 



The following differences in scalation are noted between the 

 Negros and Mindanao forms. In the former an average of 15 

 more ventrals and 4 less subcaudals is found in the males; in 

 the females there are 8 more ventrals and 4 less subcaudals than 

 are found in Mindanao specimens. The number of labials touch- 

 ing the chin shields in Negros specimens is 4 to 5 ; in Mindanao 

 specimens, 3 to 4, the larger percentage having 3. Three speci- 

 mens have the anterior part of the body decidedly coppery red 

 to maroon. 



Ophites aulicus Linnseus. 



Nine specimens were taken by Mr. McNamara. A dead speci- 

 men seen at Isabela was not preserved. 



Dendrophis pictus Gmelin. 



Common in the lowlands of the island, but I have not found 

 it in the mountains. The several specimens in the collection are 

 from Isabela, Hinigaran, Bacolod, and La Carlota. 



Oligodon modestus Giinther. 



I have not seen this snake. The type is from southern Negros. 



Elaphe erythura Dumeril and Bibron. 



Common in the lowlands. Specimens were taken at Hini- 

 garan and Isabela; three were taken by Mr. McNamara at La 

 Carlota. All of these specimens have blackish tails, but other- 

 wise agree with the same species from other islands. 



Gonyosoma oxycephalum Boie. 



A single specimen in the Bureau of Science collection was 

 taken at Dumaguete by Mr. Eskridge, of Silliman Institute. 



Dendrelaphis modestus Boulenger.* 



' Dendrelaphis fuliginosus Griffin. — An examination of the type of this 

 species convinces me that it is a specimen of D. modestus. The color on 

 which the species seems to have been based appears to have been caused 

 by some preserving fluid, sifice the flesh and the intestines are likewise • 

 discolored. The type has a few more ventrals and subcaudals than the 

 type of D. modestus, but no other difference worthy of mention could be 

 found.
