XLVIL — On Two new Species of Amphipoda Gammarina. 

 By Alfred O. Walker. 



[Plate XVI.] 



Fam. Phoxocephalidse, G. O. Sars. 



Phoxocephalus pectinatus, sp. n. (PI. XVI. figs. 1-6.) 



Epi meres of the perseon rather deeper than their segments ; 

 third pleon-segmentwith the lower margin straight, the hinder 

 slightly convex, and the hinder angle with the point rounded. 



Head with the hood slightly curved downwards; eyes 

 round, dark, and large, especially in the male. 



Upper antennas with the first joint longer than the two 

 next, its upper margin produced and the lower furred in the 

 male j flagellum 4-jointed, terminated in the male by a stiff 

 seta as long as the whole antenna ; accessory appendage 

 4-jointed, reaching nearly to the third joint of the flagellum. 



Lower antenna? in the male as in P. Holbolli, in the female 

 with the second joint of the peduncle nearly as long as the 

 first and third together ; flagellum 4-jointed, as long as the 

 second joint of the peduncle. 



First gnathopoda rather smaller than the second ; epimeres 

 distally expanded ; propodos distally contracted ; second 

 gnathopoda with the epimeres rounded-oblong ; margins of 

 propodos parallel ; in both pair the propodos is almost as long 

 as the four preceding joints, the second, third, and fourth 

 joints being very short. 



First and second perseopoda much as in P. Holbolli, but 

 with the dactylus about three fourths of the length of the 

 propodos.
