Amblycephalus hamptoni. 

 (PI. fig. 2). 



Rostral a little broader than deep ; internasals three-fifths the length 

 of the prefrontals, which enter the eye ; frontal slightly longer than 

 broad, longer than its distance from the end of the snout, two-thirds 

 the length of the parietals ; supraocular about half the width of the 

 frontal ; loreal nearly twice as deep as long ; two prseoculars and one 

 postocular, the latter produced to below the eye, which is thus excluded 

 from the labials by a narrow rim ; temporals short, 1 + 2 ; seven or eight 

 upper labials, last longest ; three pairs of large chin-shields. Scales in 

 15 rows, dorsals feebly keeled. Ventrals 202 ; anal entire ; subcaudals 

 96. Body strongly compressed. Pale brown above, with numerous 

 blackish bars interrupted on the middle of the back ; two black longitu- 

 dinal streaks on the back of the head and nape ; sides of head and lower 

 parts yellow ; a few black dots on the belly and under the tail. 



Total length 555 millimetres ; tail 150. 



A single male specimen. 



This species appears to be most nearly related to the imperfectly 

 describe^ A. modestits, Theob., from Pegu.
