GAMMARIDEA. gQ3 



males and females were found together, and are judged to belong to 

 the same species, from their similarity in the setae of the legs, the 

 narrow basal joint of the six posterior legs, the fifth epimeral hardly 

 shorter than the fourth in both, and similar caudal stylets.

 more enlarged.

Epimerals rather broad ; fifth anteriorly not narrower than fourth. 

 Eye quite large and round. Superior antennae more than half the 

 length of base of inferior, extending beyond apex of penult joint ; fla- 

 gellum about half whole length. Inferior antennae half as long as 

 body; flagellum scarcely longer than base, joints not oblong, setae 

 nearly obsolete, last joint of base longer than preceding. Hand of 

 last pair of feet slender, short hairy, apex not enlarged ; claw minute, 

 half as long as hand. Hand of second pair subtriangular, the palm 

 nearly straight, and having a sharp, slightly curved tooth on the 

 upper half, thumb (or prolonged inferior angle of hand) not like an 

 acute tooth ; following two pairs of feet subequal ; next three pairs gra- 

 dually increase in length, all rather densely setose, and first joint very 

 broad, with posterior margin slightly uneven. 



Length, about six lines. The body is naked; there are a few 

 minute hairs on the edges of the epimerals.
