*) A very plain spccies, resenibiing in form small specimens of H. 

 iigera; bul in the characters of surface and umbilication it is more like 

 a diminulive H. inornata. The whorls revolve more closely in the same 

 space, and form a more domc-shapcd spire than the incipient whorls 

 of H. pelliicida. (G.) 



'*) Very similar in characters to //. iiidecorata, but is less than lialf 

 ils size, of a very ditlercnt colour, and the umbilical region dilTers con- 

 sidcrably, especially the rellection of Ihe lip at that part, whicli does not 

 cover the portion of thc umbilicus next the aperture , biit turns round 

 at right angles to it. It may be compared to H. aUiaria. but thc um- 

 biiic is not half as large. (G.)
