Specific Cli<tiiirtri-x. /'/ ni'ilf. General form of body resembling that of 

 the 2 preceding species. Cephalic segment, however, seen clorsally, more abruptly 

 runtrarted in front, with the rostral plate more horizontal and narrowly spoon- 

 shaped. I 'rusunie comparatively shorter and less attenuated behind. Caudal rami 

 \ery short. scarcely as long as they are broad, and considerably divergent. An- 

 terior antenna\ as in the 2 preceding species, 5-articulate and rather stout. 

 Anterior lip with a very acute recurved projection in front. Last pair of legs 

 comparatively small, with the marginal spines unusually short, not extending beyond 

 the middle of the genital segment. 



Colour dark corneous. 



Length of adult female 0.86 mm. 



/.'< ///"//>. I think I am right in identifying the above-described form with 

 Scott's E. />r]ii>/i/rti,,i. with which it seems to agree fairly well in most of the 

 anatomical details, though being somewhat inferior in size. It is closely allied 

 to I-', in <ili rfiini. and may easily be confounded with that species. On a closer 

 examination, however, it is found to differ, not only in its much inferior size, 

 but also in the narrowly e\serted and spoon-shaped rostral plate, the much shorter 

 caudal rami. and the structure of the last pair of legs, which, in the shortness 

 of the marginal spines, more resembles that in E. Xr*i. 



Occurrence. I have found this form in 2 widely distant localities, viz., 



at Hvulor, lower part of the Ghristiania Fjord, and in the Trondhjem Fjord at 



lemes and Bejaii. the depth ranging from 3 to 20 fathoms. Mr. Scott also 



rerun]- it li-uin Kinmark, and it thus seems to occur along the whole Norwe- 



gian roa-t.
