standing features of the subgenus Lioielphusa ; indeed in this 

 respect it agrees better with Barytelphusa^ in which the crests are 

 well defined. It, however, differs from most species of the latter 

 subgenus in the small size of the individuals and the incomplete- 

 ness of the cervical groove , hence it may be placed in Liotelphnsa. 

 In any case its affinities with P. malabanca are unmistakable, 

 and the latter is clearly a Lioielphusa. 



The opportunity is taken of figuring the type-specimen of 

 P. malabarica^ preserved in the Indian Museum, as well as the 

 type of the new variety. 



The type of the variet}^ described above (Crustacea Reg. 

 No. ^§^) is preserved in the Indian Museum.
