large female from Stat. 144 accords with the figure, but the carpocerite hardly extends beyond 

 the antennular peduncle and the terminal spine of the scaphocerite extends as far forward as 

 that peduncle; the frontal spines are a little shorter and directed straight downward. The 

 specimen from Stat. 1 64 is mutilated, like that from Stat. 2 1 3 in which the rostrum and the 

 left supraorbital spine are missing; the terminal spine of the scaphocerite just reaches beyond 

 the carpocerite, which is hardly longer than the antennular peduncle. The small specimen from 

 Banda accords with the figure, but in that from Stat. 258 the supraorbital spines are hardly 

 shorter than the rostrum and the three frontal spines, slightly longer than in the figure, project 

 straight forward; the carpocerite, as long as the terminal spine of the scaphocerite, appears 

 again a little shorter than in the figure. The specimens taken at the Stat. 273 agree with the 

 figure, but the stylocerite reaches to or just beyond the middle of the second article and both 

 the carpocerite and the terminal spine are a little shorter. Sometimes in these specimens from 

 the Jedan Islands the supraorbital spines project straight forward. The female from Stat. 282 

 agrees with the figure, but the supraorbital spines are almost as long as the rostrum and the 

 stylocerite reaches to the middle of second article. The two ova-bearing females from Stat. 310 

 are of medium size, 13 mm. long, the rostrum extends to the end of first antennular article 

 and appears much longer than the supraorbital spines; the stylocerite reaches just beyond the 

 middle of second article and the blade of the scaphocerite to the end of the antennular peduncle. 

 In the young specimens, finally, from Stat. 3 1 5 the stylocerite reaches to the middle of second 

 article, while the carpocerite and the terminal spine of the antennal scale are hardly longer 

 than the antennular peduncle. 



The large chela much resembles that of Syti. iieovieris (J. G. de Man, 1. c. 1897, fig. 6i«), 

 but it has a somewhat more slender shape, the small chela, however, differs by the fingers 

 being constantly shorter than the palm: the palm being one and a half as long as the fingers 

 or nearly so. 



In the first carpal segment of the second legs the proportion between its length and 

 thickness is somewhat variable, this proportion varying between 5 and 5,65 ; the sum of the 

 following segments is a little shorter than the first. In younger specimens the carpus has a 

 somewhat stouter shape, the proportion between length and thickness of the first segment being 

 then 4,84 (Stat. 258), 4,73 (Stat. 164), 4,6 (Stat. 273), 4,44 (Stat. 240J and even 4,3 (Stat. 213), 

 and in very young individuals as in those from the Stations 240, 2 1 3 and 50 the first segment 

 appears a little shorter than the sum of the following. In the youngest of all the specimens, 

 that from Stat. 50, the first carpal segment is only 4-times as long as thick. The large, 

 full-grown, ova-bearing female from Stat. 144 makes a remarkable exception, for the first 

 segment of the carpus has also a stout shape (proportion 4,33) and appears one-fifth shorter 

 than the sum of the followine.

As results from the Tables of measurements, the proportions between the length of the 

 joints of the following legs are somewhat variable, like also the proportion between length 

 and width of the joints ; the joints appear the more slender, the more younger the specimens are. 



The meri of the third legs carry 3 — 5 spinules, long 0,08 — 0,13 mm., those of the fourth 

 2 or 3, rarely i. Very characteristic are the dactyli. Those of the third pair, that measure
