Hab. Banks of the Aparimao, Alto Peru ; W. Lobb.

 of which is seen through the substance of the shell.

Hab. Andes of Caxamarca, Peru ; W. Lobb. 



This differs but little from the preceding species in form and detail 

 of sculpture ; yet there is a marked distinction in the style of paint- 

 ing.

Hab. Chachapoyas, Alto Peru ; W. Lobb. 



The painting of this delicate and boldly convoluted shell is singu- 

 larly characterized by two bands of short oblong chestnut spots or 

 dashes, ranging obliquely in a direction contrary to that of the 

 painted lines.
