No. 13090 of Sclater's list missing. 



Rostral, — portion seen above half, or less than half the length of the suture between 

 the nasals. Praefrontals touch the 2nd supralabials. Frontal, — the praefrontal 

 sutures are the smallest, and the supraocular usually the largest. Temporals, — two or 

 three anterior, succeeded by two or more scales in contact with the parietals. Margi- 

 nals,— -none. Infralabiah,—^. The 4th or 5th largest. Sublinguals, — too poorly 

 developed to deserve the name. Costals juxtaposed everywhere. Ventrals absent. 



An easy snake to recognise apart from its colour, which is very distinctive. It has 

 no ventrals, no sublinguals, and no marginals, and the costals are juxtaposed through- 

 out.
