The wbole body is bright vermillion, punctulated with brown, passing 

 through orange to golden on the belly. The head and neck for ten 

 scales posteriorly is black, the labials bordered and traversed by yel- 

 low lines, and the occipitals dotted with the same. Throat and chin 

 yellow ; black spotted. The head is broad i)osterioiiy and the outline 

 converged rapidly to the acute prominent muzzle. Loreal square, one 

 preocular, two postoculars; seven upper labials; eye over third and 

 fourth; fifth very large. Ten inferior labials; scales in nineteen rows. 

 Vertical plate nearly as broad as long. Anal divided. 



Measurements. — Total length, 006 mm. Of this the tail is 175 mm. 

 in length. 



But one example of this handsome species has come under my obser- 

 vation. According to Bouleuger the Tachymenis melanocephala is the 

 same. Peters describes his specimen as follows : 



It was founded on a young specimen " which possibly belongs to T.hipunctalus, 

 Giinther, with which it agrees in respect to its pholidoisis, and in the punctulatiou of 

 the head shields and the markings on the infralabials. The ground color of the 

 head, including the najie, to the tenth row of scales posteriorly, is blackish brown, 

 behind which there is a yellowish collar around the neck four scales wide, while the 

 remainder of the body is yellowish brown above; the underside yellowish, without 

 black punctulations."
