directed spine, while in front of this spine the lower boi'der is sharply carinated. Second joint 

 nearly quadrate, hardly longer than broad, 3'^'' half as long as 2'"'; inner flagellum half as 

 loner as the carapace, rostrum included, outer flagellum a little shorter and less broad than 

 inner. Stylocerite terminating in a long and acuminate spine that reaches to the far end of 

 basal article. 



Basal antennal article sharply carinated above, near the stylocerite ; the carina runs forward 

 about to the middle and from here obliquely outward to the anterior margin ; outer spine 

 triangular, acute, reaching tO' the level of the far end of basal antennular article. Antennal 

 peduncle reaching to just be)<)nd the. middle of the antennal scale; the latter, the terminal 

 spine included, is 7,4 mm. long, three-fifths the length of the carapace, and 3,7-times as long 

 as broad in the middle ; the unarmed, straight, outer margin ends in a long, forwardly directed 

 spine, long 0,85 mm., one-ninth the entire length of the scale, and almost 3-times as long as 

 broad at its base; distal margin of the lamella truncated, nearly as long as the spine. 



The external maxillipeds reach almost to the truncated distal end of the antennal scales, 

 terminal joint as long as penultimate, antepenultimate joint reaching to the far end of basal 

 antennular article. 



The i^' pair of peraeopods (Fig. J^d, "j^e) reach with the propodus to the far end of the 

 scaphocerite and bear apparently no exopodite. The coxopodite is armed at the antero-external 

 angle with a small, acute, tooth, while the inner margin is fringed with setae. The sharply carinated, 

 upper margin of the strongly laterally compressed merus ends in a long acute spine, that 

 reaches to the far end of the carpus; the lower margin is also sharply carinated from 

 the proximal end to a little beyond the middle and this rather prominent carina is lamelliform 

 and terminates in a small, sharp tooth. The upper margin of the outer surface of the carpus 

 ends distally in a well-developed, slender spine and another broader spine, though of the same 

 length, occurs at the far end of the lower margin, two smaller acute teeth exist moreover on 

 the distal border of the upper surface. Chela without the dactylus 5,7 mm. long, almost half 

 the length of the carapace and 1,7 mm. broad in the middle, the propodus being 3,35-times 

 as long as broad in the middle. 



The very short peraeopods of the 2'"' pair (Fig. 7Sf> 75£') hardly reach to the middle 

 of the merus of the i^K The merus, 1,4 mm. long, is 7-times as long as thick and almost 

 twice as long as the carpus, that measures 0,84 mm.; a seta, 0,36 mm. long, is implanted at 

 the distal extremity of the latter, behind it a shorter one is observed and a still shorter seta 

 exists near the far end of the lower margin. The propodus is 0,6 mm. long and 3-times as 

 long as broad ; on the lower margin of this joint two long setae are implanted in the middle, 

 not far from and behind one another, of which the anterior is 0,72 mm. long, the other a 

 little shorter, and three equally long setae occur at the far end, one also at the far end of the 

 upper margin; probably also on the middle of this margin two long setae will prove to occur, 

 opposite to those of the lower margin. Dactylus long 0,27 mm. and 0,12 mm. broad, the 

 margins run parallel like those of the preceding joint and are glabrous; the rounded extremity 

 of the dactylus bears four long pectinated .setae, of which the inner pair are 0,58 mm. resp. 

 0,68 mm. long, the two external 0,48 mm.
