Ihe shell generally known as the Ach. virginea (Bulla 

 virginea Lin.) is so common, that few collectors do not 

 possess it. The varieties, however, of this species are rare, 

 and differ so remarkably in their colouring, as to require 

 illustration. Several kindred species of this family I have 

 already described ; and on the same principle of establishing 

 specific distinctions from formation instead of colour, I shall 

 now endeavour to point out those characters which are 

 common, more or less, to all the varieties of this species, 

 and which distinguish it from its allies. A. virginea may be 

 known by the comparative shortness of the basal whorl, 

 which in general is broader than high ; the margin of the 

 outer lip is entire, and sloping in an oblique direction ; the 

 aperture is wide, and nearly round ; the lower part of the 

 columella takes a concave direction, and between its base 

 and that of the outer lip is a very deep notch. The basal 

 whorl is so broad that the shell, if placed on a table with 

 its mouth downwards, will remain erect. 



Both these and the two next varieties are in Mr. Dubois' 

 cabinet. Their locality is unknown ; but my young friend, 

 Mr. Frederick Parkes, has recently sent me shells of the 

 (jommon variety, found by himself near Kingston, Jamaica.
