Description of the Female. — Body robust ; abdomen mode- 

 rately slender and composed of four segments, first segment 

 somewhat dilated in the middle ; viewed laterally this seg- 

 ment is seen to possess a spiniform and hook-like appendage 

 on the inferior aspect and near the proximal end, while poste- 

 riorly there is a distinct fascicle of hairs (PI. X. fig. 1) ; the 

 length of the specimen is about 1 millim. {^^ of an inch). 

 The antennules are twenty-four-jointed, as in Stephos minor^ 

 but the proportional lengths of the joints differ somewhat, as 

 shown by the formula (see also PI. X. fig. 2) —
