 C. 10-70 f. From Prof. Mobiu.s's notes and di-awiug, wliieli 

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

 animal diilers considerably from that of Cerithium, parti- 

 cularly in respect of the foot and odontophore. I wuuld 

 consequently adopt the genus Triforis of Deshayes for this 

 species.

 shell in the genus Fleurotoma ; but it has no iissurc or notcli, 

 and the ajjex is that of Trophon. It, however, wants an 

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

 peculiar, so that it may constitute the tyjje of a new genus, 

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