LIST OF SNAKES COLLECTED IN BORNEO 79 



BoiE. Ablabes thus disappears from current nomenclature, a 

 very fortunate result, since few generic snake names have been 

 oftener misapplied. 



Four specimens, 2 males and 2 females. They differ con- 

 siderably in color as is usual in this variable species, but the 

 scale formulas are normal. The males have 129 ventrals and 

 75 subcaudals; the females 143 and 139 ventrals with 65 and 

 69 subcaudals respectively. 



Holarchus purpurascens (Schlegel). 



For use of the generic name in place of Simotes see my 

 Herpetology of Japan, 1907, p. 353. The present species may 

 be designated as the type. 



A single male specimen. Scutellation normal; 19 scale 

 rows; 176 ventrals; 1 anal; 54 subcaudals. There is one sub- 

 ocular. The color is very dark and dull, the head pattern and 

 the dorsal cross bars being nearly obliterated. Two dorsal 

 longitudinal dark stripes are very conspicuous when the speci- 

 men is submerged in the alcohol. It resembles very closely a 

 specimen in the U. S. National Museum (No. 38068) collected by 

 Dr. W. L. Abbott at Gunong Patung, West Borneo. These 

 dusky stripes are also well marked in a young specimen from 

 Java (U. S. N. M. No. 62618) with otherwise well marked color 

 pattern. 



Oligodon everetti (Boulenger). 



A single male specimen of this rare species, the type of 

 which came from Mt. Kina-Baloo, has the following scale for- 

 mula: 



sc. 15; ventr. 137; an. 1; subc. 65; supral. 7; oc 1 +2; 

 temp. 14-2. 



It will be noticed that the number of ventrals is small and 

 that of the subcaudals greater than in the type which is a fe- 

 male. The color pattern agrees very well with the latter as 

 described and figured by Boulenger (Gat. Sn. Brit. Mus., vol. 2,
