HYPERIA PREHENSILIS, N.S. 



Spec$C character. Superior antennae about the length of the head. Both 

 pairs of gnathopoda with the carpus and propodos simple. Three hind pairs 

 of pereiopoda subprehensile at the tips. 



Length, three-twentieths of an inch. 



THIS species differs from H. tauriformis next described in 

 having longer antennae, the proximal margins of the carpus 

 and propodos of hoth pairs of gnathopoda not serrated, and 

 in having the propodos of the last three pairs of pereiopoda 

 inferiorly produced and armed with short strong cilia. This 

 gives a prehensile character to the last three pairs of pereio- 

 poda that we have not recognized in other species. 



Taken at Banff, by Mr. Edward, with the preceding species.
