110 Proceediugs ofthe Asiatic Society of Bengal. [No. 1, 



serrated ridge along the back : guiar pouch in the males only, covered 

 with small keel-less scales of equal size ; the other scales of the lower- 

 parts conspicuously carinated ; those of the upper-parts minute, arrang- 

 ed in irregular transverse series (as best seen by aid of a lens), their keels 

 presenting a tuberculated appearance except tovvards the ridge of the 

 back : a row of about ten large tubercles on each side commencing from 

 the occiput. Colours various, but fugitive in spirit ; the young being 

 much speckled and reticulated with greyish-black, and the full-grown 

 mostly plain, with dark bands on the tail more or less distinct. 

 Length 12 in., of which tail 8^ in. Common at Port Blair. 



Of Snakes, we have received five harmless and two venomous species. 

 The former are — 



Lycodon aulicus, (L.). Uniformly coloured variety. 



Üendrophis pictus, (Gm.). Some beautiful varieties. 



Dipsas hexagonotus, nobis, J. A. S. XXIV, 360. Several young 

 epecimens. The adult remains to be described. 



Heepetodeyas peasinus ; Coluber prasinus, nobis, J. A. S. 

 XXIII, 291. Large. Also inhabits the base of the Himaláya, Asám, 

 Tenasserim, &c. 



Ceebeeits boefoemis, (Schneider). 



The latter— 



Hamadeyas yittatus, (Elliot). 



Tuimesueus vieidis, (Lacepéde), var. Cantori, nobis, J. A. S. 

 XV, 377. A Teimestjeus which appears to be exceedingly common 

 both in the Andamán and Kicobar islands is altogether similar in 

 structure to the common Te. yieidis, but varies much in colouring, 

 being grass-green, brown, or blackish, either uniformly coloured or 

 variously mottled ; but only in one mottled specimen from the Nico- 

 bars do I perceive the lateral line on the scales bordering the abdo- 

 minal plates, which is commonly seen in continental examples of Te. 

 yieidis. In a green example from Port Blair, 4 ft. in length (!), 

 there is no trace of this ; but I may here cali attention to the fact 

 that there are certainly two nearly afíined species confounded under 

 Te. yieidis. One common in Lower Bengal has the scales more 

 strongly carinated, very conspicuously so on the sides of the head, 

 while those oí' the crown are roughly granular (a modification of the 

 more developed keels), instead of being flat or almost flat as in the
