 witb dorsal fascicle of setules but no spiues; segmeuts 5 and 6 eacb 

 Avith 2 dorsal gToups containing 1 or 2 spinules a piece. He;id, lateral lobes 

 truncate, a little prominent. Side-plates 1 — 4 with setules wide apart; side- 

 plate 1 very little expanded, 4*^ scarcely as broad as deep. l^leon segnients 



2 and 3, postero-lateral corners acutely produced. Eyes oval renit'orra. dark. 

 Antenna 1 less thau ^/g as long as body, l*** Joint large, fully as long as 2^ and 3^ 

 combined, flagellura slender, longer tban peduncle, IG-jointed. accessory 

 flagelluiii 4-jointed. Antenna 2 a little shorter, ultiniate Joint of peduncle 

 shorter tban penultimate. flagellum 8 — 11-jointed. Gnatbopod 1 in 9 , 6^^ Joint 

 oval, palm ratber oblique, in gnatbopod 2 rather larger, oblong, palni less oblique. 

 Gnatbopod 1 in d, 6*^\joint narrowly oblong, palm sinuous, oblique, in gnatbo- 

 pod 2 nearly twice as large, broadly oblong, palm less sinuous, botb gnatbopods 

 raore powerful than in o . Peraeopods 1 and 2, 4*'' Joint ratber large, 4**^ and 5**1 

 setose. Peraeopod 3, 2^^ Joint rounded quadrangular. Peraeopod4, 2*^ Joint widely 

 expanded, except distally, wbere tbere is scarcely a fi"ee corner. Peraeopod 5, 

 2*^ Joint very large, bind margin serrate, evenly convex, tbe expansion much 

 produced downward in a broad obtusely truncate lobe. Uropods 1 and 2, 

 rami nearly equal, with apical spines, tbe inner also with 1 or 2 lateral 

 spines. Uropod 3 reacbing nnicli beyond tbe otbcrs, outer ramus twice as long 

 as peduncle, friuged with setae, 2*^ Joint very small, inner ramus scale-like, 

 little more than half as long as peduncle. Telson scarcely as long as broad,

Body rather slender and compressed, pleon segments 4 — 6 each with 

 dorsal median fascicle of setules, segment 5 with 2 spinules among tbe setules, 

 •and oblique lateral rows of 3 spines and 2 or 3 spinules, segment 6 with 

 lateral groups of 2 spines. Head, lateral lobes angularly prominent. Side- 

 plates 1 — 4 with few setules, 1^* scarcely expanded distally, 2^ and 3*^ 

 rounded distally, so that tbe lower edges are not continuous, 4*^ not so 

 broad as deep. Pleon segments 2 and 3, postero-lateral corners slightly 

 produced. Eyes oblong oval, dark, close to margin of head. Antenna 1 scarcely 

 more than V4 as long as body, 3'^ Joint half as long as I^S flagellum longer 

 than peduncle, 9-jointed, accessory flagellum witb 2 joints, the last minute. 

 Antenna 2 shorter. ultimate Joint of peduncle little or in ö not at all shorter than 

 penultimate, flagellum half as long as peduncle, with 5 joints in o , 7 in d, which 

 has both peduncle and flagellum brush-like. Gnatbopods 1 and 2 in o rather 

 small, 6* Joint oval quadrangular, palm nearly transverse, in gnatbopod 2 

 the ö*'^ and 6*^^ joints are rather longer, giving a more slender appearance, 

 in the ö botb gnatbopods much stronger, not very unequal, though gnatbopod 2 

 is the larger, 6*^ Joint large, oblong, palm slightly oblique, sborter than the 

 bind margin, finger strong. Peraeopods 1 and 2 ratber slender. Peraeopods 



3 — 5 coinparatively short and stout, 2* Joint in peraeopod 3 subquadrate, 

 in peraeopod 4 broadly expanded above, narrowed below, in peraeopod 5 

 much larger, with broad expansion abruptly contracted near the distal end. 

 Uropods 1 and 2, rami equal, with apical spiues, inner also with spinule at 

 middle of inner margin. Uropod 3 reacbing beyond the others. outer ramus 

 with fascicles of spines but no plumose setae, 2*^ Joint small, distinct, inner 

 ramus small, shorter than the short peduncle. Telson short, broad, lobes
