The first variety was found by Mr. Cuming on the leaves of bushes 

 at Tanhay in the isle of Negros. 



The second or unstriped variety was taken by him in the island 

 of Siquijor on leaves of trees. Among the latter, some faintly- 

 striped individuals show the transition from one variety to the other. 

 The young of the striped variety have stripes ; but the young of 

 the unstriped variety are of a uniform pale yellow. (W. J. B.) 



Bulinus Calista. Bui. testd diaphand, anfractibus 7 subventri- 

 cosis pallide flavd albido strigatd; apice subroseo vel roseo-cas- 

 taneoj labii limbo castaneo-purpurascente. 



Var. a. long. 2^ ; lat. 1 J poll. 



Intervals in the whitish epidermis leave the yellow ground-colour 

 in sufficiently well-defined longitudinal irregular stripes, which are 

 often zigzagged. Found on bushes. 



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 ochraceous red and a white 

 apex. Found on the leaves of trees. 



Var. c. Flava; apice roseo, labii Umbo castaneo. 



Long. 2; lat. j-^ 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 nitide 

 flavd ; apice et labii limbo albis. 



Long. 1J; 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. 



Hab. ad Tanhay in insula Negros.

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

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