TJie Amphipoda of Bennuda. Ill 



Second gnathopods very large, with hand elongated and narrow 

 with the palm uniformly excavate and occupying Vs entire length

Head rounded and provided with acutely pointed spinous pro- 

 cesses. There may be 2 processes directed forwards and situated 

 above and behind the eye, or there may be a single process in the 

 middorsal line and also one just lateral to the base of the second 

 antennae. Second thoracic segment with spinous process in mid- 

 dorsal line situated at about middle of segment, anterior margin 

 with large process laterally and also several just dorsal to articu- 

 lation of second gnathopod. These processes are variable in size 

 and occurrence. 



Eyes large, circular, situated near anterior margin of head. 



First antennae rather slender, more than ^/2 as long as body • 

 peduncle over ^{^ as long as flagellum which is made up of numer- 

 ous elongated segments ; first joint of peduncle moderately stout, 

 cylindrical ; second joint about twice as long as first and not so 

 broad ; third joint less than ^/2 as long as first, broader at distal 

 than proximal end. Second antennae much shorter than first, ex- 

 tending as far as first third of flagellum of first ; flagellum 2-jointed, 

 first joint 1^/2 times as long as distal one, as long as fourth joint 

 of peduncle ; gland cone rather prominent ; third joint longer than 

 broad ; fourth and fifth joints subequal and slender, with a few setae. 



Mandibles with 3-jointed palp, of which the first is short and 

 C3'lindrical and about twice as long as broad ; second joint slender, 

 of about the same width as first but more than twice as long ; third 

 joint shorter than second, broader at distal end than at proximal,
