Note. Another Elapine snake is mentioned by STERNFELD: 

 Ultrocalamus burger si n. sp. from New Guinea. As the head had 

 been dried, the head-shields could not be seen very distinctly. 

 The specimen had 15 rows of scales; internasals absent. Ven- 

 trals 293; subcaudals 40. Brown above; scales of outer row 

 margined with light; upper lip and end of tail yellow. Length 

 330+ 35 mm.

 vertically elliptic; nostril between two nasals; praeocular in 

 contact with or narrowly separated from the posterior nasal.

 in length; mandibular teeth decreasing in length. Body round, 

 covered with smooth scales without pits, in 15 rows; ventrals

Snout short, rounded. Rostral slightly more broad than 

 deep, visible from above; posterior nasal in contact with the 

 praeocular; internasals half as long as the praefrontals; frontal

 than the parietals; one prae- and one postocular; temporals

 caudals 41, partly single, partly in two rows. Tail ending in 

 a pointed scale, which is keeled above.
