orbicular in form, dactylus comparatively short, lanceolate ; last pair much smaller 

 than the 2 preceding pairs. Uropoda exceedingly small, resembling in structure 

 those in the 2 preceding species. Colour of dorsal face light yellowish, with the 

 edges of the segments somewhat darker, caudal segment yellowish brown. Length 

 of adult female 272 mm. 



Remarks. This is a very distinct species, and ought perhaps to be re- 

 garded as the type of a separate genus, differing, as it. does, in several points 

 rather essentially from the other species. 



Occurrence. Only a few specimens of this form have hitherto come un- 

 der my notice. They were taken, some in the outer part of the Hardanger 

 Fjord, at Mosterhavn, some in the Stavanger Fjord, the depth ranging from 150 

 to 200 fathoms. Out of Norway it has not yet been recorded.
