the length of the 6 !h and the terminal joint is but little broader than long; the outer margin 

 both of the 6 th and the 7 lh joint is fringed with spiniform setae. 



The external maxillipeds reach in the adult female to the distal fourth of the antennal 

 scale ; the well-developed exopodite reaches in the male almost to the middle of the penultimate 

 joint ; the terminal joint is a little more than 3-times as long as the penultimate, the proportion 

 being like 10:3, just as in the yourig specimen from Ternate. All the described mouth-parts 

 are taken from the left side of the male. 



Excepting the 5 th pair all the legs bear well-developed epipodites. The legs of the i st pair 

 are as long as in the young specimen from Ternate, but the 2 nd pair extend to the apex of 

 the antennal scale; in the female the 2 nd joint of the carpus is 2y 2 -times as long as the 1 st , 

 the chela one-fourth shorter than the carpus and the palm one and a half as long as the 

 fingers. The dactylus ends in two curved claws, that embrace the single claw of the immobile 

 fineer, when the fingers are shut; at the base of the claw of the immobile fineer one observes, 

 at the inner side, a very small tooth or spine. 



The three posterior legs diminish considerably in length from the 3 rd to the 5 ,h and 

 they are comparatively just as long as in the young specimen from Ternate, the 3 rd pair 

 reaching to the end of the external maxillipeds, the 5 th to the anterior margin of the carapace. 

 They agree with the original description, but, owing to these specimens being full-grown, they 

 bear a somewhat larger number of spines and setae. The merus of the 3 ld pair is armed, in 

 the female, on the middle third of its posterior margin with 4 stout spines, that increase in 

 length from the posterior to the anterior and the posterior is a little farther distant from the 

 2 nd as the 2 nd from the 3 ld and as the 3 rd from the 4 th ; a 5 th spine, as long as the 4 th , occurs 

 just behincl the distal extremity. A spine, as long as the 5 th of the merus, occurs, besides 3 

 or 4 smaller ones, at the far end of the lower margin of the carpus and a smaller spine stands 

 on the middle of the posterior margin. The posterior margin of the propodus is armed with 13 

 spines of somewhat unequal length, that are of a more slender form than those of the merus 

 and at the base of each 2 or 3 setae are implanted, a few spines and setae are implanted 

 on the lateral surface near the posterior margin and 7 or 8 similar spines occur on the anterior 

 margin, also accompanied by a few setae; the dactylus, finally, has 5 spines on its posterior 

 margin. The legs of the 4" 1 pair agree with those of the 3 ld , as regards the number of spines 

 and setae. The merus of the 5 th pair carries 2 spines in the middle, a third near the proximal 

 and a fourth near the distal extremity, carpus as in the preceding legs; there are 14 slender 

 spines on the posterior margin of the propodus and 3 or 4 on that of the dactylus. In the 2 nd 

 pleopods of the male both the stylamblys and the appendix masculina are well-developed. 



Eggs not very numerous, rather large, oval, 0,8 — 0,9 mm. long. 



The male from Stat. 153 is hardly longer than the male from Ternate, carapace and 

 rostrum being together 7,6 mm. long; it fully resembles it, but the median spine on the posterior 

 marein of the 6 th somite measures two-thirds the leneth of the lateral. The small tubercles at 

 the base of the i st tooth of the rostrum and on the middle of the carapace are well-developed. 



General distribution: Ternate (de Man).
