Variety B. cyanochloris. — Dififers from A in the ground colour 

 which is blue-green, sometimes of a peculiarly vivid hue. The 

 scales are more conspicuously outlined with black. There is no 

 light flank stripe or a very obscure and ill-defined one, with no 

 black lines above or below. The Ijelly is eau-de-Nil or yellowish- 

 green between the ventral keels. 



Length. — I have examined two juvenile erythritic specimens, 

 apparently hatchlings from the Nicobars, captured on the 27th of 

 October, 1880, that measured 254 and 263 mm. (10 and To| 

 inches). The largest example measured by me was 1220 mm. 

 (4 feet). 



Food. — A gecko provided the meal on one occasion, a frog on 

 another. 



Breeding. — One gravid female has passed through my hands 

 killed in July. It measured 1087 mm. (3 feet 6J inches). 



Lepidosis. — As in A. The ventrals, 175 to 207. Subcaudals, 

 129 to 153. 



Dentition. — From five skulls in my collection. Maxillary, 20 

 to 21, coryphodont. Palatine, 13 to 14. Pterygoid, 18 to 26. 

 Mandibular, 20 to 23. 



Distribution. — Eastern Himalayas ; Assam, Burma; Nicobars.

 17568, Ind. Mus.). 



Note. — I have seen about thirty examples, four of which 

 were erythritic specimens. These latter are brown dorsally and 

 ventrally. The lore, the postocular stripe, the oblique anterior 

 lateral bars and the edges of the scales are darker brown instead 

 of black. Nos. 8897 and 8898 in the Indian Museum both appar- 

 ently hatchlings from the Nicobars are examples. A third speci- 

 men of mine is also from the Nicobars. An adult in the Indian 

 Museum with no number and no recorded locality is another 

 example. In this the hue is cigar-brown dorsally and ventrally, 

 rather lighter in hue between the ventral keels. Like the juvenile 

 examples a still darker brown replaces the black marks of the usual 

 blue-green specimens. 



Variety C. andamanensis.—ln this the prevailing hue is much 

 like the last, being a bright blue-green. The scales are still more 

 conspicuously outlined with black. The posterior two-fifths of 

 the vertebrals are black. Oblique black lateral bars are more or 

 less in evidence. There is no light flank stripe, and no black 

 lines on the flanks, or on the tail. The belly is yellowish-green.
