 Female, 4 mm, Sta. 2344. 



Fig. J, peraeopod 5. 



second antenna is short, having about 10 articles but in the fully- 

 developed male it consists of long articles and the antenna is as long 

 as the body; young males exhibit stout but short flagellar articles. 



Epistome not produced. 



Gnathopods 1 and 2 similar in size and morphology. 



The head has the lower antennal corner extended down acutely 

 and in some specimens it is distinctly produced (see plate 59, fig. A), 

 but not as much as in Proharpinia. 



Peraeopod 5 has article 2 cut into a number of teeth which are 

 short but acute ; between each tooth is a seta ; the number of setae range 

 from 6 to 17; in some specimens each intersetal tooth may be double- 

 pointed, especially near the ventral edge. 



Uropod 1 : rami with 3-6 moderately long setae, the outer ramus 

 slightly longer than the inner. Uropod 2 : outer ramus reaching farther 

 than the inner, peduncle with long setae, rami undefined apically, 

 inner ramus with 1-2 setae, outer with 3-4 setae.
