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

 both of the 6"'' and the 7''' 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 young specimen from Ternate. All the described mouth-parts 

 are taken from the left side of the male. 



Excepting the 5'"^ pair all the legs bear well-developed epipodites. The legs of the i^' pair 

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

 the antennal scale; in the female the 2"^ joint of the carpus is 2'/., -times as long as the i ^t, 

 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 

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

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



The three posterior legs diminish considerably in length from the 3''*^ to the 5''^ and 

 they are comparatively just as long as in the young specimen from Ternate, the 3'"'^ pair 

 reaching to the end of the external maxillipeds, the 5'*^ 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"^ 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"'' as the 2"*^ from the 3"^ and as the 3^'* from the 4''^; a 5''' spine, as long as the 4''^, occurs 

 just behind the distal extremity. A spine, as long as the ^^^ 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''' pair agree with those of the 3"', as regards the number of spines 

 and setae. The merus of the 5''' 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°^ 

 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 

 margin of the 6^^ somite measures two-thirds the length of the lateral. The small tubercles at 

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



General distribution: Ternate (de Man).
