In the male the legs of the Ist pair are as long as the antennal 

 scales, in the adult female they usually reaeh with the fingers 

 beyond them; in the adult female tlie carpus is a little more than 

 twice as long as the chela, the fingers slightly shorter than the palm. 



The 2d legs (Fig. Ik — 1;<), strenger and longer than the legs 

 of the Ist pair, extend in the adult, ova-bearing female with the 

 chela and with one-fourth or one-fifth of the carpus beyond tlie 

 antennal scales, in the younger females, as e. g. in an ova-bear- 

 ing specimen, long 39 mm., the carpus of the 2J legs extends 

 only as far as the terminal spine of the scaphocerite, so that 

 only the fingers and two-thirds of the palm reach beyond the 

 tip of tlie scales ; in the male specimens, that are of a smaller 

 size, only the chela projects beyond the scale or even only a 

 part of it. Almost as a nde in the tijpical funn the carpm appears 

 (HstinctJij loHf/er than the chela. In 41 of the 45 Scandinavian 

 specimens, in wliich the legs of the 2tl pair were still present, 

 i. e. in 91 per cent., this fact was observed : only in tiro ova- 

 bearing females from Denmark and in one young male from 

 Svendborg Sund the carpus ])r()ved to be just as long as the 

 chela and only in one almost adult female wdthout eggs from 

 Denmark the chela w^as slightly longer tlian the carpus : in this 

 female, long 50 mm., the coalesced portion of the sliorter ramus 

 of the outer flagellum was about one and a half as long as the 

 free portion, also in other respects this female proved to be quite 

 typieal. The carpus, which is longer than the merus, appears of 

 a rather dender form, 8- to 9-times as long as thick at its distal 

 extremity. Fingers litlle more than hal f as Ion;/ as thr paJiii, the 

 proportion being as 9 : 16 (Fig. 1/), palm slightly more than 

 4- to almost 5-times as long as wide. The fingers (Fig. \in) are 

 armed with a small tooth at the proximal end of their cutting- 

 edge as usual, while the dactylus bears, moreover, a tooth near 

 the articulation. 



The three ambulatory legs are rather stout. In the adult female 

 those of the 3d pair reach to the distal extremity of the anten- 

 nal scales, while those of the 5tli are hardlv shorter, reaching as
