This Pliocene fossil of Calabria and Sicily has been dredged living 

 in the Bay of Biscay and Gulf of Marseilles by the ' 7 T /vm//Y/r/rr ' 

 and at numerous points in the Atlantic and Mediterranean by the 

 'Porcupine'. It lives in 174-1025 fms. Jeffreys says : The small 

 fossil originally described and figured by Philippi did scant justice 

 to this beautiful shell, which has now been discovered to he still 

 living. My finest specimens are about seven-tenths of an inch in 

 length and breadth ; the color is cream, with the tint of a blush rose ; 

 and the sculpture is variable as regards the beaded rows of strise. 

 Young specimens have a deep umbilicus which is inclosed within a 

 sharp ridge. The callous which covers the umbilicus in the adult 

 is proportionally thinner than in BaHiynurpliiln et<xj>ira Di\\\. 



C. FOLINI Fischer. Unfigured. 



Shell covered umbilicate, corneous, little elevated, whitish flesh 

 colored; suture piano-canaliculate; whorls scarcely convex, the 

 penultimate minutely ornamented with 11 spiral, elegantly beaded 

 line; beneath marked with 12 simple or divided, scarcely gran ulose 

 line ; umbilical area bounded by a spiral sulcus, covered by a central 

 callous ; aperture oblique, subquadrate. 



Alt. 13, diam. 17 mill. (Fischer.) 



Algeria, 900 meters.
