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 2 72 mm. 



Remarks. — This is a very distinct species, and ought jterhaps 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 20(> fathoms. Out of Norway it has not yet been recorded.
