carpus almost half as long as the merus, 3-times as long as thick and with 2 small, movable 

 spinules, long o, 18 mm., at the far end of its posterior border. Propodus twice as long as the 

 carpus, 8,4-times as long as broad, its posterior margin armed with 15 small spinules and both 

 margins beset with tufts of rather long setae; dactylus one-sixth the propodus, differing from 

 that of Syn. Stimpsonii by the accessory claw that makes a right angle with the posterior 

 margin and that appears almost as thick as the principal claw; the latter appears more 

 slender than in the figure 3^ of my quoted paper. The carpus and the merus are also setose 

 along their margins. While the merus of the 4 th legs bears the same tooth as that of the 

 3 rd , in the 5 th legs this joint is unarmed, like as in Syn. Stimpsonii. 



The male from Stat. 282, of the same size as the preceding one, fully accords with it, 

 but the large cheliped is missing. Brachium of small cheliped 4-times as long as broad, upper 

 margin terminating in a small, acute tooth, the lower margins as in the large cheliped. Small 

 chela half as long as the carapace, 4-times as long as high, fingers half as long as the palm, 

 shutting together and of equal length. The egg-bearing female has also nearly the same size, 

 but the rostrum reaches the end of first antennular article. Eggs ovoid, not very numerous 

 and rather large, o, 7. mm. long. 



The male from Stat. 91 is 15 mm. long. Rostrum one and a half as broad at its base 

 as it is long, a little shorter than first antennular article, orbital spines also as in the type. 

 This is also the case with the antennal and antennular peduncles, but the visible part of the 

 first antennular article appears only one and a half as long as the second. Telson typical, 4,3- 

 times as long as its posterior margin is broad, the width of the latter one-third the width at 

 the base ; spinules on the upper surface typical. The large chela, however, closely resembles 

 that of Syn. Stimpsonii (de Man, 1. c. fig. 3 a), the dactylus has quite the same form and the 

 cutting-edge is entire. The following legs agree also with this species, for the 3 ld — 5 th legs are 

 of a somewhat stouter shape than those of the typical specimens from the Stations 213 

 and 282. So e. g. the merus of 3 vd legs appears 5-times as long as broad, the carpus is almost 

 half as long as the merus, 3-times as long as thick and bears 3 short spinules at the far end 

 of the posterior margin ; the propodus is almost twice as long as the carpus and 6-times as 

 long as broad; the accessory hook, finally, of the dactylus, though being also at a right angle 

 with the posterior margin, appears somewhat smaller. 



In the ova-bearing female from Stat. 91 which has the same size as that from Stat. 282, 

 the rostrum just reaches beyond the first antennular article, the visible part appears as long 

 as in the preceding male. The stylocerite reaches to the 2 nd third of second antennular article. 

 The carpocerite is somewhat longer than the antennular peduncle, the blade of the scaphocerite 

 reaches to the tip of that peduncle, but the terminal spine, that extends as far forward as the 

 carpocerite, projects only with x j s or 1 / 9 of its length beyond the tip of the blade, but is not 

 curved inward. Telson typical, but only 3,8-times as long as its posterior margin is broad. It 

 appears doubtful whether the large cheliped that is lying loose in the bottle, belongs really to 

 this female; the infero-internal margin of the brachium is namely armed with a strong acute 

 tooth at the far end, the anterior border of the upper face of the carpus bears three acute 

 teeth and the posterior border ends in a strong acute tooth; the fingers are shorter, the dactylus
