Note. Another Elapine snake is mentioned by StERNFELD: 

 Ultrocalamus biirgersi 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.

Snout short, rounded. Rostral slightly more broad than 

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