being as long or even slightly longer than the joint is wide, 2 or 3 spines are moreover doublé. 

 The dactyli (Fig. 9^), that resemble those of the genus Car/diua H. M.-Edw., are 0,9 mm. long, 

 almost half as long as the propodi and 4-times as long as wide at base; they are armed on their 

 posterior margin with 5 stout spines, including the terminal claw, that increase in length from 

 the i st to the last. Carpus of 4 th pair 1,23 mm. long, propodus 2,1 mm., the latter a little 

 longer in proportion to the carpus than in the 3 rd pair; there are 3 spines on the anterior 

 border of the carpus but only one on the posterior near the distal extremity. Propodus 7-times 

 as long as wide, with only 2 small spines on the proximal half of the anterior margin, but 

 with 9 strong spines on the posterior margin, some of which are again doublé. The dactyli are 

 0,85 mm. long and fully resembly those of the 3 vd pair, 4 spines, increasing in length, being 

 implanted posterior to the terminal claw. Carpus of 5" 1 pair 1,2 mm. long, propodus 2,32 mm. 

 long, almost twice as long as the carpus ; there are 4 or 5 spines near the anterior border 

 of the carpus, one at the far end of the posterior margin, with a smaller spine behind it. 

 Propodus of a slenderer form than those of the 3 rd and 4 th pair, 9-times as long as wide; 

 there are 3 small spines on the proximal half of the anterior margin, while the posterior is 

 armed with 1 1 articulating spines of somewhat unequal length, though generally becoming longer 

 distally, the longer of the two spines at the distal extremity measuring 0,38 mm., one and a 

 half as long as the propodus is wide. The dactylus (Fig. 9 h) is 0,72 mm. long, a b o u t on e-t h i r d 

 of the propodus, and almost 4-times as long as wide at base ; it is armed with 8 spines, including 

 the terminal claw; these spines are of a less stout shape than those of the dactyli of the 

 3 rd and 4 th pair, but also increase in length from the proximal one to the terminal claw. Like 

 the meri, also the carpi and the propodi of the three posterior legs are provided with a few 

 feathered setae. Ova not very numerous, comparatively large, 0,65 mm. long and 0,4 — 0,48 

 mm. wide. 



The two young specimens from the Stations 33 and 65a show nothing remarkable, 

 but the meri and carpi of the i st and 2 nd pair of legs are still almost devoid of spines. 



General distribution: Ternate.

 Museum van Natuurlijke Historie te Leiden, 19 18. Deel IV, afl. 3, p. 159. 



Stat. 95. June 26. 5°43'.5 N., U9°4o'E. Sulu Sea. 522 m. Stony bottom. 1 female. 



A new species at first sight distinguished from the six other species of this genus by the 

 lower margin of the rostrum being smooth, not denticulate. The only specimen collected 

 measures 1 1,78 mm. from tip of rostrum to tip of telson ; measured in the middle line the cara- 

 pace proves to be 2,16 mm. long, the rostrum 1,38 mm., the abdomen 8,24 mm.: it is probably 

 a young female. The rostrum (Fig. ioa), that measures two-thirds the length of the carapace, 

 runs horizontally forwards to about the middle of the 2 nd joint of the antennular peduncle; the 

 upper border, slightly convex above the orbital margin, runs downward to the acuminate tip, while 

 the lower margin is slightly concave. In a lateral view the rostrum, not including the teeth,
