.it' 7 well-deiined articulations, the 2nd of \vliicli is produced behind to 

 :i strong conical projection. I'o-terior antenna' and oral parts nearly as in L. 

 ,/fl'i. 1st pair of legs comparatively more slender, with the outer ramus dis- 

 stinctly .">-artieulate and exceeding half the length of the 1st joint of the inner, 

 apical claw of the latter ramus rather elongated, being fully .'5 times as long as 

 the distal joint. Natat'-n hr- resembling in structure those in /.. cornufa, yet 

 differing in the absence of an\ s.-ta inside the pioximal joint of the inner rainus. 

 l.i-t pair of h"_ r s much smaller than in the type species, distal joint narrow fusi- 

 form in outline, inner expansion of proximal joint triangular in form and scarcely 

 nding to the middle of the distal joint, number of marginal set;u in both 

 joints as in /,. <-i,ni/if<i. 



M'tli- exhibiting the usual sexual differences from the female. Inner ranuis 

 of :!rd pair of legs with the projection of the middle joint peculiarly transformed, 

 being converted to a sigmoid lamella with 2 knob-like prominences of the outer 

 edge :ind partly cowering the last setiferous joint. Last pair of legs with the 

 distal joint narrow linear in form and carrying 5 setae, one of "which, attached 

 to the imi'T edge, is rather strong, spiniform; inner expansion of proximal joint 

 almost obsolete, with '2 unequal seise. 



Colour yellowish, tinged with light red or orange.

///// ',/,.-. This is unquestionably the species originally described by Glaus 

 under the name of ('/,!/< serrata, as clearly shown by the figures he gives of the 

 1st ami last pairs of legs. The form recorded by Th. Scott as I.<i'>iili>,>if<- /iro- 

 /itin/rn is identical with Claus's species. It is well distinguished from /,. rnrntttti 

 liy the distinctly 7-articidate anterior antenna', the .'{-articulate outer ranuis of the 

 1st paii- of h-gs and the rather different shape of the last pair of legs. Moreo\er 

 the anal operdc wants the erect spine found in /.. mnitiln, and the caudal rami 

 carry each at the tip L J normally developed seta' instead of a single such. 



Occurrence. 1 ha\e met with this species not iinfrei|uently in many place- 

 l"th ot' the -oiith and west CO of Norway, as also in the Trondhjem Fjoid.
