30 Canon A. M. Xorman — Xotes on the 



seo^ment-:!, is moderately dilated and rather more than half the 

 entire length of the abdomen. 



The caudal furcfe are slender and elongated, their length 

 being somewhat greater than that of the last two abdominal 

 segments combined. 



Hah. Bog Fiord ; apparently rare. 



The species is provisionally ascribed to the genus Herr- 

 manella of Canu*; the second maxillipeds are, however, 

 more feebly clawed than those of any of the species alreadv 

 described, and because of this and one or two other diff.^rence^ 

 this East Finmark form should, perhaps, be placed in another 

 genus ; but it will be necessary to have more perfect speci- 

 mens ere its position can be satisfactorily determined.
