Hab. ? 



The painting of this shell is very characteristic, and the 

 outer surface of it is fui-ther distinguished by its smooth 

 porcelain appearance. It is an extremely rare species ; 

 the specimen represented in the ' Conchologia Systema- 

 tica ' is in Mr. Cuming's collection, and that here figiu'cd 

 from the British Museum was formerly in the Taukcrville 

 collection, afterwards in that of W. J, Broderip, Esq.

 Hab. Benguela, West Africa. 



All Mr. Cuming's examples of this species are distin- 

 guished by the same broken inteiTupted style of painting 

 with which this is characterized. 



Species 38. (Mus. Cuming.) 

 Achatina columna. Achat, tesld elongato-turritd, an- 

 fractibus septem, subrude granoso-striatis, sufuris de- 

 presso-concavis, columella contortd, callosd, plicato-

 fulguratd, columella et apertura fauce c<erulescente- 

 albis. 

 The column Achatina. Shell elongately turreted, 

 whorls seven in number, rather rudely granosely 

 striated, sutures depressly concave, columella twisted, 

 callous, produced in the form of a plait, aperture 

 small; ycUow, streaked throughout with naiTow 

 chestnut flames, columella and interior of the aperture

 Limax flammens, Martyn. 

 Kelix columna, Chemnitz. 

 Hab. Prince's Islands, West Africa. 



It is somewhat remarkable that no species has been dis- 

 covered to approximate to this. Lamarck, believing it to 

 be an inhabitant of freshwater, placed it originally in the 

 genus Lymnaa.
