littlo smaller; tlio carpus appears in tlio adiilt male almost twiee, 

 in the adult female twice or nearly twice as long as the cliela. 

 In younger individiials the carpus appears with regard to the 

 ehela a littlc shorter: so in a specimen, long o5 mm., the carpus 

 is hardly more than one and a half as long as the chela and in 

 a very young specimen, that measures 27 mm,, the carpus is 

 uot yet one aiul a half as long as the chela, the chela bcing 

 1,C mm, long, the carpus 2,2 mm. In the adult male the fingers 

 are scarcely shorter than the palm or just as long, but in the 

 adult female the palm appears '/g to '/:; longer than the fingers. 



In the male the legs of the 2^ pair usually reach with the 

 chela beyond the antennal scales, sometimes, in the adult, with 

 the chela and a small portion of the carpus, '/s ^^ 7g5 more 

 rarely only with four-fifths of the chela. In the adult, egg-bearing 

 female these legs do also not iuvariably extend equally far for- 

 wards, in some specimens they reach by the chela and two-fifths 

 of the carpus beyond the antennal scales, in ethers only by one- 

 fourth of the carpus or by the chela alonc, in other adult 

 individuals the carpus attains even not yet the end of the 

 scales and in these specimens the 2'i legs project only by four- 

 fifths of the chela beyond the scaphocerites. At a younger age 

 the 2^ legs reach not so far: in a specimen, long 45 mm., little 

 more than the fingers extends beyond the scales and in individuals, 

 26 mm. long, even the fingers reach only for a part beyond them. 

 The legs of the 2*1 pair (Fig, 3i — 3A-) are longer and stronger 

 than those of the l^t and usually of equal length, rarely one leg 

 appears a little longer than the other; they dosely resemhle those 

 of L. adsperms (Rathke), In the Table at page 160 the 2d legs 

 of 24 specimens from the Hollandsch Diep have been accurately 

 measured under the microscope, namely of 13 males and 11 females: 

 these measurements lead to the foUowing conclusions. 



In the male the carpus seems to be constantly a trifle shorter 

 than the merus, though not more than 0,4 mm,, in the adult 

 female, however, the merus appears often a trifle shorter than 

 the carpus. The carpus appears in the male G — 7-times as long
