 Zamenis arenarius, i>0M/e«</. Faun. Ind., Hejjt. p, 329 (1890). 



Very closely allied to Z. diadenvi, but distinguished by the much 

 larger rostral, which is considerably dee])cr than broad and wedged 

 in far between the internasals ; the portion of the rostral vi.sible 

 from above measures one half to two thirds its distance from the 

 frontal. Three or four prajfrontals in a transverse row ; frontal 

 nearly as long as its distance from the end of the snout, shorter than 

 the parietals ; three or four loreals ; two prtcocnlars, three ])0sl- 

 oculars, and three suboculars separating the eye from the labials ; 

 temporals small, scale-like ; ten upper labials ; five lower labials in 

 contact with the anterior chin-sliields, which are as long as the 

 ]»osterior. Scales obtusely keeled anteriorly, very distinctly pos- 

 teriorly, in 25 or 27 rows. Yentrals not angulate laterallv, 227 ; 

 anal entire ; subcaudals 80. Cream-colour or pale buff, with darker 

 spots disposed quincuncially, and a longitudinal streak on each side 

 of the nape ; lower parts uniform white. 



Total length (of the specimen in the Calcutta Museum) 930 

 millim. ; tail 175.
