tary and resembling those of Eudactylina. Second 

 pair of maxillipeds large and furnished with powerful 

 claws. Thoracic legs, four pairs, well developed and 

 biramose; each ramus three-jointed, and furnished 

 on the inner margin with long plumose setae. 



The male has a general resemblance to the female 

 but is considerably smaller. The thoracic and ab- 

 dominal segments are also narrower than in the female, 

 and the abdomen is distinctly three-jointed.

Female. Length, exclusive of the furcal setae, 

 4'5 mm. Cephalic segment moderately broad and 

 flattened and having the antero-lateral margins con- 

 cave, giving rise to a broadly-rounded forehead. 

 Posterior margin furnished on each side with a strong 

 movable spine, the apex of which is somewhat cheli- 

 form, and reaches to the end of the first free segment 

 of the thorax. The eyes, two in number, situated in 

 the front portion of the segment, a V-shaped band of 

 chitin with a pointed end traversing the segment from 

 front to rear (PI. LXX, fig. 1). The three thoracic seg- 

 ments short and quadrangular in outline, the second 

 being distinctly shorter than the other two. The third 

 segment considerably longer than the first and nearly 

 twice the length of the second, with its lateral margins 

 slightly inflated posteriorly. All three segments pro-
