Distr. India and Malay Archipelago. 



No. Lxxv. Huh. Buntal. 



A female. Dental formula |-; rostrum ju3t overreaches 

 the scaphocerite. The first tooth is situated behind the level 

 of the hepatic spine ; antennuhir peduncle shorter than 

 scaphocerite. 



This specimen is certainly identical with Dr. de Man's 

 species ; but I do not separate it from P. indicus because, on 

 a comparison of some examples of the latter in the Museum 

 collection with two of Dr. de Man's specimens and ray own, 

 I find them essentially similar in all respects but two — the 

 proximal half of tlie rostrum is raised into a very prominent 

 crest and its first tooth is situate behind the hepatic spine. 

 The first of these distinctions is certainly a very obvious one 

 and very striking ; the second less so. It is hard to decide 

 whether these characters are of specific importance ; for 

 myself, should a larger series demonstrate their constancy, I 

 should still be inclined to consider P. merguiense as a variety 

 only, though a well-marked one, of P. indicus.
