( Vol. II p. 18.**) 



HYPEUIA PREHENSILIS, N.S. 



Specific character. Superior antennas about the length of the Lead. Both 

 pairs of gnathopoda with the carpus and rjropodos 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 antennas, the proximal margins of the carpus 

 and propodos of both pairs of gnathopoda not serrated, and 

 in having the propodos of the last three pairs of pereiopoda 

 interiorly 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.
