Mr. Cuming informs us that the animal of this elegant shell, 

 which in the form of the spire and the distribution of the colouring, 

 though not in the colouring itself, reminds tlie observer of Achatinte 

 fasciata, emarginata and virginea of Swainson (Zool. 111.), varies 

 much. In all the varieties the broadly expanded lip is white, both 

 above and below, and the bands of the body- whorl terminate 

 abruptly upon its upper part, so that the shell almost looks as if the 

 wide white lip had been added to some of the Riband Achatinee, 

 for varieties of which some of the young might be taken by a cursory 

 observer. The animal was ash-coloured, darker above. General 

 length of the shell about two inches ; width of body-whorl from f ths 

 to ^ths of an inch.

Some of the varieties of this fine shell, especially variety b, will 

 remind the observer, at first sight, of the species last described ; but 

 Mr. Cuming informs us that the animal is reddish brown, and, be- 

 sides other differences in the shell, the colouring-matter, instead of 

 stopping short at that point of the body-whorl, just where the lip 

 begins to expand, is continued on to the very rim, which is in most 

 instances bordered with it ; nay, the colour generally becomes more
