beyond the rostrum, while the merus reaches as far forward as the antennal peduncle. The 

 merus is apparently coalesced with the ischium to one single joint, that is 3,35 mm. long; the 

 upper margin of this joint is glabrous and unarmed, but 9 or 10 articulating spines are implanted 

 on the middle of the outer surface, of which spines one in the middle of the joint and one at 

 the far end are a little larger than the rest. The carpus is 3,25 mm. long and nearly 12-times 

 as long as wide in the middle, while it is a little wider at the distal extremity, where it is 

 0,3 mm. broad; the upper margin is armed with 9 spinules, of which the spine at the distal 

 extremity, 0,2 mm. long, is the longest of all and almost as long as the joint is here wide, 

 9 partly somewhat longer spines are implanted on the outer surface near the upper margin. 

 Chela 2,95 mm. long, a little shorter than the carpus; the very short palm, which is 

 only 0,34 mm. long, appears in a lateral view near the articulation of the fingers 0,38 mm. 

 broad and its posterior border is distinctly emarginate. The fingers are equal and in a lateral 

 view gradually narrow to the apex, that is not acute, but obtuse, and 0,06 mm. broad; their 

 upper border bears a few very small spinules, near each of which a short hair is implanted ; in 

 front of the described notch the posterior border bears a tuft of feathered, spiniform setae, 

 while that border is fringed along its whole length with feathered setae, which at the base of 

 the finger are 3 mm. long, at the apex 1,5 mm. 



The legs of the 2"'* pair are only as long as the rostrum. The coxopodite is armed 

 with a spine at the far end of the posterior border. Like in the r'-' pair ischium and merus 

 seem to be united to one joint, that is 3,2 mm. long and 11 -times as long as wide in the 

 middle; the upper margin is glabrous and unarmed, except a spine, long 0,21 mm., at the distal 

 extremity, while one observes a row of 5 spines on the outer surface, placed at unequal distances. 

 The carpus is 2,65 mm. long and 0,25 mm. broad in the middle, 10 — ii-times as long as 

 broad and a little widened at the distal extremity, like in the i^' pair; upper margin with 7 

 or 8 spines, while there is moreover a row of 7 spines on the outer surface near the upper 

 margin. Chela 2,66 mm. long, just as long as the carpus; the propodus, which is less 

 deeply notched posteriorly than in the i^' pair, is 0,27 mm. broad in a lateral view, one-tenth 

 the length of the chela, for the rest the chela resembles that of the 1*' pair and like in this 

 all the joints are fringed with long feathered setae along the posterior border. 



The three posterior legs are of a stout shape, those of the 3''^^ pair are a little shorter 

 than the scaphocerite ; they slightly decrease in length, so that the legs of the 5'^ pair reach 

 only by their dactyli beyond the antennal peduncle. It remained doubtful whether also in these 

 legs ischium and merus are coalesced to one joint or not. The meri that decrease in thickness 

 from the 3'^"^ to the 5''\ are unarmed, excepting a strong spine at the far end both of the upper 

 and the lower margin, but there are on the lower a few brownish, stout, feathered setae of 

 moderate length. The carpi of the 3"^'' pair are 1,35 mm. long, measured along the anterior 

 margin, which is armed with a small sjjine just beyond the middle and a smaller one just behind 

 the middle; 4 or 5 spines are implanted on or near the posterior margin and one at the far 

 end of the outer surface. The slightly curved propodi are 2 mm. long and 6 or 7-times as 

 long as wide; their posterior margin is armed with 8 articulating spines, which from the i*' or 

 posterior to the anterior somewhat increase in length, those on the distal half of the margin
