1,08 mm. long and 0-times as long as thick at base. In 2 speci- 

 mens from Port Said the 2^ joint proved to be a little less 

 slender, namely only 2,1-times as long as thick: my supposition 

 that this less slender shape was caused by the younger age of 

 these specimens proved to be correct, for the same form and 

 proportions were shown by a specimen from the English Channel 

 the size of which was the same. 



Except only the two ova-bearing females from Rovigno (Fig. 4:d) 

 and a specimen, long 70 mm., from Port Said, in all the speci- 

 mens the legs of the 2^^ pair (Fig. 4c) project by one half to 

 four-fifths of the fingers beyond the antennal scales, in the two 

 egg-bearing females from the Adriatic and in this Port Said 

 specimen, howcver, bi/ the fingers and half the palm. Carpus always 

 distinctly shorter than merus and as long or slightly longer than 

 the fingers, the latter nsually a little longer than the palm, rarely 

 just as long. 



The legs of the 5tli pair reach to the tip of the antennal scales, 

 in the two egg-bearing females from Rovigno they project even 

 by the dactyli beyond them. 



The two egg-bearing females from Rovigno mnst, in my opi- 

 nion, be referred to L. serratus (Penn.). The rostrum presents 

 the same form and toothing as the typical species, in the larger 

 female, long 105 mm., the shorter ramus reaches hardly 2 mm. 

 beyond apex of rostrum, while in the other it is 1 mm. shorter 

 than the rostrum, just as observed also in the typical serratus 

 from the English Channel. 



The mandibular palp shows quite the same form and characters. 

 The only difference that I see, is presented by the second legs, 

 which, like in the variety TreiUiana, project by the fingers and 

 half the palm beyond the scales, while in the typical species from 

 the English Channel these legs reach only by one half to four- 

 fifths of the fingers beyond them.
