would lead to the conclusion that Bulini Diana and Calista belong 

 to the same species. (W. J. B.)

A dark rosy-purplish stripe borders the columella, which is itself 

 tinged with red. I have seen but two specimens, one with an in- 

 jured lip, and in that the columella is not subangulated as it is in 

 the more perfect one. (W. J. B.) 



Bulinus Dactylus. Bui. testd valde product d, attenuatd, anfrac- 

 tibus 7, ultimo cceteros aequante, brunned, epidermide cinerascente ; 

 aperturd ovatd, earned vel albidd; labii limbo castaneo -purpuras -

 Through the ashy epidermis the brown ground-colour appears in 

 most of the specimens in the shape of obscure longitudinal stripes : 

 in very old specimens scarcely any striping is apparent. The brown 

 ground-colour is well shown near the aperture, where the attrition 

 of the animal has exposed it. Very old shells are all but opake : 

 younger ones are subdiaphanous. There is in all that I have seen an 

 obscure brown fillet towards the base of the body- whorl. (W. J. B.) 



Bulinus Boholensis. Bui. testd elongatd, graciliore, subdiaphand; 

 anfractibus 6, lineis incrementi oblique striatis ; ochraceo-cine- 

 rdscente strigis longitudinalibus angulatis distinctis ornatd; labii

The brown ground-colour appearing through the ochraceous- 

 cinerascent epidermis produces the stripes of this elegant shell. A 

 small portion only of the ground-colour is exposed by the attrition
