shorter than the immobile finger and its upper margin is more strongly arcuate. The eggs are 

 a little larger than those of the typical female from Stat. 282, they are 0,9 mm. long. 



The young male from Stat. 305 is 11 mm. long. The rostrum extends to the middle of 

 second antennular article, but the orbital spines that are a little turned outward, measure but 

 one-fourth the length of the rostrum. The antennular peduncle fully agrees with my figure 3 (1. c.) 

 of Syn. Stiinpsonii, the visible part of the first article is but one-fourth longer than the second, 

 but the stylocerite is som.ewhat shorter than the first article. Carpocerite a little longer than 

 the antennular peduncle, the blade of the scaphocerite reaches only to the end of the second 

 article and the terminal spine, that is not curved inward and that extends by one-third of its 

 length beyond the tip of the blade, appears as long as the antennular peduncle. The lower 

 spine of the basicerite reaches a little less forward than the orbital spines. 



The telson is typical, 4-times as long as the posterior margin is broad, width at the 

 base 3-times as broad as the posterior margin; the spinules of the upper face are arranged as 

 in the typical specimens from the Stations 213 and 282. The larger cheliped resembles that 

 of Sy7i. Stimpsonii, the other chela is hardly half as long as the larger and much smaller. 

 First carpal segment of 2°<i legs a little shorter than the sum of the four following, the 2^^ — 4"^ 

 segments are equal in length. The following legs show the same somewhat stouter shape as 

 the specimens from Stat. 91, but the almost rudimentary accessory claw of the dactylus is 

 directed as in the figure 36- of my quoted paper. 



The female, collected by Mr. van Nouhuys east of Segli, is 24 mm. long and larger than 

 all the specimens collected by the "Siboga"; in its features and outer appearance it much 

 resembles the egg-bearing female from Stat. 91. The eggs are also 0,9 mm. long. The frontal 

 spines are abnormally developed. The rostrum that just reaches beyond the i^' antennular 

 article, is slightly turned to the right and bears, just behind the middle of its left margin, a 

 small, acute spine, somewhat directed outward; the right orbital spine is directed straight 

 forward, but the left distinctly outward. At either side of the body the lower spine of the 

 basicerite is slightly turned outward and appears as long as the lateral frontal spines. 



The visible part of i^' antennular article is one and a half as long as the 2"*^ and the 

 2°'i almost twice as long as the 3'*^. The stylocerite of the left peduncle extends to the apex 

 of I ^' article and its tip is slightly curved outward ; the stylocerite of the right peduncle, however, 

 is directed straight forward and decidedly a little shorter than i^' article. The carpocerite hardly 

 reaches a little beyond the antennular peduncle, the terminal spine of the scaphocerite is as 

 long as this peduncle and the scale reaches just beyond the apex of the 2"'^ article. 



Unfortunately the large cheliped is wanting, the smaller fully agrees with that of the 

 female from Stat. 9 1 . The upper margin of the merus terminates in a small spine, fingers 

 hardly more than half as long as the palm. First segment of the carpus 5,6-times as long as 

 wide at the distal extremity, its length in proportion to the sum of the four following segments 

 as 113 : 94, 2'^'^ segment just as long as the 4* and slightly longer than the 31'^, 5'!^ segment 

 almost twice as long as the 2°<i, chela a little more than twice as long as the ^^^ segment, 

 fingers one-third longer than the palm. The measurements of the 3'<i legs are: merus 2,1; 

 carpus I; propodus 1,8. Merus 5,5-times longer than wide, propodus 7,25-times; the propodus
