Boulenger described three species of Denisonia from the Solo- 

 mons, namely D. par. (1), J), woodfordii (2), and D. melanura 

 (3). Subsequently Kinghorn (3), and later Burt (5) showed 

 that par and melanura are synonymous, the former name taking 

 priority. There is considerable variation within these species 

 both in scalation and coloration, but the present specimens are 

 quite distinct. Mr. Clarke notes that he saw numbers of this 

 snake, and that the specimens secured are of average size and are 

 full grown. 



The new species is smaller than par or woodfordii; it has a 

 a single postocular; it has an undivided nasal; it has fewer sub- 

 caudal scales. It further differs from par in having paired sub- 

 caudals, and from woodfordii in being darker and more uniform 

 in colour.
