distal joint of the inner ramus in 3rd and 4th pairs has only 3 setse, and that 

 the terminal joint of the outer ramus in 4th pair is shorter* with only 3 spines. 

 Last pair of legs differing more conspicuously, distal joint much smaller and oval 

 in form, with only 5 setse, the innermost one quite normal; inner expansion of 

 proximal joint less broad, but rather prominent, extending as far as the distal 

 joint; marginal setse 4 in number, the outermost but one much longer than 

 the others. 



Male with the 2nd pair of legs scarcely at all transformed, having only 

 the rami somewhat more elongated than in female. 3rd pair, on the other hand, 

 very unlike those in the female, the outer ramus being exceedingly powerful and 

 incurved, with the spines strongly developed and the setse of the inner edge spini- 

 form; inner ramus distinctly 3-articulate, with the middle joint produced outside 

 to a mucroniform process. 4th pair of legs likewise somewhat transformed, having 

 the outer ramus considerably more strongly built than in female. Last pair of 

 legs very small, though having the distal joint well defined and edged with 4 

 slender setse. 



Colour yellowish. 



Length of adult female 0.72 mm. 



Remarks. This form was very imperfectly characterised by Boeck, and 

 it was for this reason not recognised by Prof. Brady, who described under the 

 name of L. cufticauda a different species, viz., that recorded above as L. Stromi. 

 It is indeed closely allied to that species, but evidently specifically distinct, dif- 

 fering, as it does, in some of the structural details very conspicuously, for instance 

 in the much fuller development of the outer ramus of the posterior antennse, the 

 rather unlike shape of the last pair of legs in both sexes, and finally in the some- 

 what different transformation of the natatory legs in the male. 



Occurrence. I have met with this form not unfrequently in the upper 

 part of the Christiania Fjord in moderate depths, as also in some places of the 

 south coast of Norway. Boeck found a single specimen at Haugesund, west coast 

 of Norway. It is very probable that it also occurs off the British Isles, but has 

 been confounded with the preceding species.
