*) A very plain species, resenibling in forni smali spccimens of H. 

 ligera; but in the ctiaracters of surface and umbilication it is more like 

 a diminutive H. inornala. The whorls revolvo more closely in the same 

 space, and form a more dome-shaped spire than the incipient whorls 

 of H. pellucida. (G. ) 



") Very similar in characters to H. indecorata, but is less than half 

 ifs size, of a very dilTerent colour, and the umbilical region differs con- 

 siderably, especially the retlecfion of the lip at that part, which does not 

 cover the porlion of the umbilicus next the aperture , but turns round 

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

 bilic is not lialf as large. (G.)
