178 Indian and Malayan Amphibia and Mejitilia, [No. 3» 



that of Burmese Reptiles (p. 33 in Ext. from Yol. X of Journ. Linn. 

 Soc, London, Zool.). Male specimens when in breeding season have 

 the lower labials, and the whole of the skin and throat beautiful- 

 ly blue black, the latter conspicuously mixed with red. One specimen 

 from Moulmein (measuring 12£ inches of which the tail is 8£) has 

 the crest high on the neck, but it becomes almost obsolete in half 

 the length of the body ; scales in 52 longitudinal series round the 

 body. The largest specimen I measured was 16 inches total length, 

 and it may even attain a larger size, though I never saw one of 24 

 inches, but it is no impossibility, as which Mr. Theobald 

 appears to regard Griinther's quotation. 



That the crest almost totally disappears at half the length of the 

 body is, I find, of common occurrence in Burmese specimens which 

 I possess from Arracan, Bassein, Rangoon and Moulmein, and the 

 throat seems to become blue in males and females, during the sum- 

 mer season at least ; in the males, however, the red colour on the 

 throat is prevalent, while it is almost wanting in the females. 



Young specimens, four and five inches in length, have the head 

 very short, thick, the centre of the occiput with a large plate sur- 

 rounded by a few larger scales ; the head has numerous dark cross 

 bands, which on the body are somewhat more distant and angular ; 

 these specimens look so different that one would be inclined to regard 

 them as belonging to a totally distinct species. 



Down at Penang, the Welesley Province and Singapore I have 

 not met with this species, it seems to be there replaced by Bron- 

 chocele cristatella. 



In M o u a t ' s Advent, and Res. among the Andaman Islanders 

 (Lond., 1863, p. 365) Blyth states that this species has also 

 been received from the Nicobars. Its occurrence is by no means 

 improbable, but I have not received it from there, nor can I 

 find a specimen of that species from the Nicobars in the Society's 

 collection.

 During live the prevalent colour* is bright green, but the changes 

 are almost quite as varied and instantaneously effected, as in a
