In abundance at Trondhjem, between Munkliohnen and 

 the land, and in other phices, 20-70 fathoms. I have also 

 found it in profusion in shallow water, 3-5 fathoms, at 

 Vadsii, and in Bog and Klosterelv Fiords, Sydvaranger. 

 Sars also found it "i stor Mtengde" at Vadso, in 6-10 

 fathoms, and also at Christiansund. It is remarkable that 

 this Diastylis^ originally described from specimens procured 

 by Capt. Holboll in Greenland, should be the latest addition 

 to our knowledge of the Cuuiacean fauna of the Norwegian 

 coast, and not recorded again till about thirty-six years after 

 its first discovery. The circumstance of its not having been 

 found is the more remarkable since the species is an inhabi- 

 tant of shallow water and is gregarious and most abundant 

 where it occurs, and that it is now known to range from 

 the borders of Kussia (Sydvaranger) to Denmark. In form 

 it is utterly different from any other species of the genus, 

 being at once distinguished by its upturned rostrum, in which 

 respect a counterpart may be found in Eudorellopsis deformisj 

 Kroyer.

Two specimens, Trondhjem, 20-40 fathoms. I have also 

 dredged it at Drobak and in the Hardanger Fiord; off Va- 

 lentia, Ireland; and procured it at Naples. 



43. Leptostylis ampuUaceus, Lilljeborg. 



Rodberg, in 250-300 fathoms. This is a rare species 

 which I have also taken at Drobak (Sars's locality) ; and I 

 am indebted to Prof. Lilljeborg for specimens from Kullen, 

 Sweden.

Carapace sculptured, with three oblique subcrescentic crests 

 on each side ; the lowest commencing at the anterior extre-

 border until it arches over the back near the dorsal mar<>-in •
