10. cinerea, Gask., (f. 92*, 93). — C. testa subcylindraceo- 

 ovali, rufeseente-cinerea, nigro punctata et lineata, fasciis 

 latis saturatioribus tribus ; basi marginibusque albescenti- 

 bus, rotundis, incrassatis ; apertura latiuseula, subspirali, la- 

 bio crassiusculo ; dentibus circa viginti, regularibus, promi- 

 nulis ; columella medio prominulo dentibus circa octodecim; 

 extremitatibus obtusis, punctis minutissimis nigris notatis. 



11. claka, Gask., (f. 91*, 222). — C. testa quam C. cinerea 

 magis cylindrica, basi medio prominula, extremitatibus ele- 

 vatis ; apertura angustiore ; dentibus magis numerosis, mi- 

 noribus. 



12. Reevii, Gray, (f. 40, 41). — C. testa ovata, tenui, ven- 

 tricosa ; dorso pallicie purpureo-fusco, obscurissime quadri- 

 fasciato ; basi albida ; spira exserta, rosea, extremitatibus 

 roseis ; apertura utrinque ampla, medio subcontracta ; denti- 

 bus parvis, tenuibus, numerosis. 



Note. — Isabella (and controversa), cinerea, clara, Reevii. 

 Comparisons between many specimens and varieties of Isabella 

 and controversa have finally resulted in the opinion that they 

 are one species, and that the proposed separation was rightly 

 abandoned by Dr. Gray. Cinerea and clara were almost 

 equally difficult to decide, but the result is the maintenance 

 of the second species, on account of the greater coarseness 

 of the teeth and flatness of the base in cinerea. Specimens 

 of Reevii usually have the appearance of undeveloped shells, 

 and, when placed side by side with partially developed spe- 

 cimens of cinerea, are found to bear a considerable resem- 

 blance to them. The species, however, is quite distinct. 



13. irrorata, Soland., (f. 304, 305). — C. testa oblongo- 

 subcylindracea, depressa ; dorso purpureo, punctis numerosis 

 fulvo-fuscis adsperso, lateribus basique albidis castaneo 

 punctatis; basi complanata ; dentibus parvis, coluinellas an- 

 ticis conspicue prominentibus. 



Note. — The remarkable prominence of the anterior co- 

 lumellar teeth in this pretty little species, distinguishes it 

 from any others of similar form. 



14. xnterrupta, Gray, (f. 271-274). — C. testa oblongo- 

 cylindracea ; dorso superne subquadrato, subplicato, punctis 

 flavidis minutis punctato, maculis castaneis flammulatis in 

 seriebus depositis picto ; extremitatibus productis, callosis, 

 lateribus albidis ; basi casruleo maculata ; apertura angustata ;
