 Hob. Bogota. 



A pretty little shell, varying considerably in form and colour, but 

 the lip appears to be always thin and prettily edged with red. Of 

 the two specimens lent me for description by Mr. Da Costa, one is 

 nearly white, profusely sprinkled with small brown spots, while 

 the other is of a yellowish straw-colour (more decided yellow 

 towards the apex), with only a few pale spots. I have as yet only 

 seen very ievi specimens, but these exhibit considerable variations in 

 their proportions. One apparently abnormally inflated specimen 

 measures nearly 15 millimetres in width and only about 20 in 

 ength ; while the narrowest specimen measures scarcely more than 

 11 millimetres in width to 21 in height.

Hab. Bogota (Mus. Dn Costa). 



I have as yet only seen a single specimen of this species, which 

 may be found to vary as much as the last. It seems, however, to be 

 distinct from any hitherto known.
