Of the 4'*' legs of the male the ischium, that is 0,9 mm. or i mm. long, is armed on 

 the lower margin with a strong spine, 0,76 mm. long, almost as long as the joint itself; some 

 fine setae, the longest of which reach to the far end of the merus, occur along the distal half 

 of the upper margin. Merus 1,3 mm. long and a'/j-times as long as broad; there is a spine in 

 the middle of the lower margin and another just before it, while posterior to the spines 5 or 

 6 long setae are implanted; a tuft of long setae occurs along the distal half of the upper 

 margin. Carpus 1,04 mm. long, presenting the greatest width at the distal 6^^, nearly twice as 

 long as thick; on the lower side of the distal margin 4 or 5 short spines are implanted, that 

 decrease in length towards the articulation, like also some long setae. Propodus hardly shorter 

 than merus, nearly twice as long as broad, lower margin with long setae, shorter ones along 

 the proximal half of the upper. Uactylus hardly shorter than merus, 5-times as long as wide, 

 with 10 or II spiniform setae along the three distal fourth parts of the posterior margin. 

 Exopodite extending to the middle of the merus. The 4"^ legs (Fig. 7:') of the female resemble 

 those of the male. In an adult ova-bearing female the ischium is 0,8 mm. long, 0,66 mm. 

 broad, the large spine measures 0,82 mm.; the merus is 1,5 mm. long, 0,62 mm. broad, the 

 carpus 1,2 mm. long, 0,55 mm. broad, the propodus 1,02 mm. long, 0,47 mm. broad, the 

 dactylus, finally, long 0,86 mm., 0,24 mm. broad. 



A long slender spine, measuring 0,52 mm., occurs, in the s'*' leg of the male, on the 

 lower border of the basipodite, not far from the distal extremity; the ischium is 0,94 mm. long 

 and 0,64 mm. thick, one and a half as long as thick; a short spine occurs at the distal end 

 of the upper margin, like also a tuft of setae, that e.xtend almost to the far end of the merus, 

 the lower margin bears also some setae, while a short conical spine exists at the distal 

 extremity, nearly of the same size as the spine on the upper border. The merus, 1,3 mm. long 

 and half as broad, bears a tuft of long setae at the distal end of the upper margin, while there 

 are 2 or 3 spines on the lower. The carpus, 1,35 mm. long and 0,42 mm. broad at the distal 

 end, is as long as the merus and is about 3-times as long as broad; it is armed with 2 or 3 

 spines near the distal end of the lower margin, while several setae are implanted along this 

 margin, of which 4 or 5 of the longest reach almost to the end of the dactylus. The propodus 

 is 0,86 mm. long and 0,36 mm. wide, 2Y.,-times as long as wide; the lower margin is furnished 

 with several long strong setae, that extend beyond the dactylus and the latter, 0,75 mm. long, 

 slightly shorter than the propodus, bears 7 or 8 spiniform setae along the two distal thirds of 

 the lower margin. 



In the female (Fig. yw) the basipodite of the s"' legs bears a long spiniform seta, twice 

 as long as the spine that occurs here in the male ; there is no spine at the distal end of the 

 upper border of the ischium, while the distal setae seem to be shorter than in the male and 

 the spine at the distal end of the lower border is also smaller. Two spines are observed near 

 the middle of the lower border of the merus, of which the posterior is a little longer than the 

 other; these spines are longer and slenderer than the 2 or 3 that are here found in the male. 

 The exopodite reaches to the middle of the ischium. 



Ova very numerous, small, 0,5 — 0,55 mm. long. 



The three specimens from Stat. 37 are nearly of the same size, hardly 7 mm. long;
