It is not without doubt that I have separated this shell specifically 

 from the last ; but in addition to the difference of shape, the colour- 

 ing matter, here again, instead of stopping short just above the outer 

 lip, where it begins to expand, as is the case with Bui. fictilis, is 

 carried on and over the external expanse of the outer lip, so as to 

 constitute a coloured rim on its lower external edge. In other re- 

 spects there is much similarity between the two. General length 

 about 1^ inch; breadth across body-whorl rather more than half an 

 inch.— W. J. B.

 The appearance of the different varieties of this species might lead 

 to the supposition that they were distinct species, in consequence of 

 the peculiarities of the outer portion of the epidermis. The whole 

 epidermis of this species seems worthy of particular notice : it con- 

 sists of an inner coat, which is rather thick, horny, apparently strongly 

 adhesive, and of a greenish brown yellow colour ; and of an outer 

 partial coat, which is white and hydrophanous, and which does not 

 entirely cover the inner coat, but is variously arranged upon it in 

 the different varieties. The following are the most remarkable va- 

 rieties : — 



a. Shell brown, with two very dark-brown spiral bands, a lighter 

 antesutural band, and a very dark columellar band. Lip white at 

 the back as well as in front. From the island of Marinduque. 



b. Shell coloured similarly to the last, but having its outer sur- 

 face slightly rugulose. From the same locality. 



c. Shell coloured similarly to the two former, but with an exter- 

 nal white epidermis disposed in slightly interrupted spiral bands. 

 Found on the leaves of trees in Tayabas, in the province of Taya- 

 bas. Island of Luzon. 



d. Shell light brown, with a dark- coloured antesutural band, and 

 very dark columellar band ; external white epidermis disposed as the 

 last. From the same locality. 



e. Shell brown, not banded, with the white external epidermis
