 This species is nearly allied to Bulinus citrinus, but differs from it 

 in many points. B. Guimarasensis is without transverse striae, and 

 the whorls are comparatively ventricose. In B. citrinus all the 

 striped varieties which I have seen are marked longitudinally. 



The var. b. of Bui. Guimarasensis has a narrow chestnut trans- 

 verse line very near the suture of the body-whorl, the base of which 

 body- whorl, below the transverse band, becomes greenish. A brown 

 stripe adjoins and borders the columella. 



Var. a. is 2^ inches long b)- 1^- inch broad. 



Var. jS. is less.

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 tlie other. 

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

 the unstriped variety are of a \iniform pale yeUow. (W. .1. B.)

Intervals in the whitish epidermis leave the yellow ground-colour 

 in sufficiently well-defined longitudinal irregular stripes, which are 

 often zigzagged. Found on bushes.
