Var. b. Gracilior, nana. Long. 1^ ; lat. ^ poll. 



The shell of this variety is rather thicker. Among them some 

 occur with the lip barely tinged with ochracecus red and a white 

 apex. Found on the leaves of trees. 



Var. c. Flava ; apice rosea, labii limbo castaneo. 



Long. 2; lat \^ poll. 



Found on the leaves of bushes. Some have an obscure narrow 

 transverse band on the body-whorl. 



Var. d. Subflava, epidermide albo-cinerascente ; fascid basalt nitidt 

 flavd ; apice et labii limbo albis. 



Long 1^; lat 1^ poll. 



Found on the leaves of bushes. Among these some occur which 

 still retain the coloured lip and tinged apex. In the very young 

 state the shell is perfectly transparent.

The last variety bears a strong resemblance to Bulinus Diana; nor 

 should I be at all surprised to see some intervening varieties that 

 would lead to the conclusion that Bulini Diana and Calista belong 

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

A dark rosy-purphsh 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.)

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. Tliere is in all that I have seen an 

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