C. PERVERSUM, L. B. C. iv. 261, and v. 217, pi. 80. f. 5. 

 C. 10-70 f. From Prof. Mobius's notes and dra-wing, wliicli 

 he was so good as to show me at Kiel, it appears that the 

 animal differs considerably from that of Cen'fhnim, parti- 

 cularly in respect of the foot and odontophore. I would 

 consequently adopt the genus Triforis of Desliayes for this 

 species.

T. MoRCHi, {Morcliii) Malm, = /???« fZew^rsa, Tiber!. G. 30- 

 230 f. ; Corsica (Tiberi) ! Sars placed this remarkable little 

 shell in the genus Phurotoma ] but it has no lissure or notch, 

 and the apex is that of Tropkon. It, however, wants an 

 operculum, the canal is very short, and the sculpture is 

 peculiar, so that it may constitute the type of a ncAv genus, 

 say Taranis'\. This is truly one of the " sea's rich gems."
