NOTES ON SOME CRYLON SNAKES. 397 
Family UROPELTIDA. 
RHINOPHIS OXYRHYNCHUS (Schneider). 
A very fine specimen 520 mm. (1 foot 83 inches) long was 
killed at Vavuniya on August 10. The costals two heads- 
lengths behind the head are 19, at midbody 17, and two 
heads-lengths before the vent 17. Ventrals 211. Subcaudals 
5 (the last 4 entire). This proved to be gravid, and contained 
ten eggs about 16 by 9mm. No trace of embryos could be 
discovered. 
Family COLUBRIDA, 
POLYODONTOPHIS SUBPUNCTATUS (Dumeril & Bibron). 
Two specimens from Anasigalla. 
“A 2 324 mm. (122 inches) long killed on July 14 has 170 
ventrals and 50 subcaudals. A ¢* 317 mm. (123 inches) 
long, date uncertain, has 171 ventrals and 56 subcaudals. In 
both the supralabials are 10, the 8th cuneate and not reaching 
the margin of the lip, the 4th, 5th, and 6th touching the eye. 
NEROpIA pIscator (Schneider). 
One variety asperrimus from Anasigalla. 
One variety typica from Vavuniya is uniform brown 
dorsally in the posterior two-thirds of the body. Anteriorly 
there are four series of smallish, black, rather indistinct, 
quincunciate spots, the outer row almost obsolescent. In 
both these specimens the keels are exactly alike, being absent 
in the last row only in the anterior part of the body, but 
present and rather feeble before the vent. 
AMPHIESMA STOLATUS (Linné). 
Two specimens from Anasigalla and one from Vavuniya. 
A 2 628 mm. (2 feet 2 inch) long, killed at Anasigalla on 
August 17, is gravid and contains five eggs. Both the Anasigalla 
specimens have unusually large, black, well-defined, lateral, 
ventral spots, especially anteriorly.
