Prof. Loven in his ' Catalogue of the Mollusca of Western 

 Scandinavia ' enumerates three species of tliis order ; but we were 

 not fortunate enough to procure a living or dead s])ecinien of 

 either species. We dredged at the entrance of Drontheim fiord 

 three dead specimens of a species of Cleodora.
