prettily radiated by distant impressed lines, the in- 

 terstices being perfectly smooth. 



4. H. *lhieata, (vol. 1. p. 18.) On examination of 

 several individuals of this species, I have ascertained 

 that a character exists in this species, that was alto- 

 gether wanting in the specimen from which I drew 

 out the description published in the first volume of 

 this work. As the shell is somewhat translucent, 

 two pairs of white teeth, remote from each other, may 

 be observed through the body whorl of the shell. 

 One pair of these teeth is placed in the throat so near 

 to the labrum as readily to be seen by looking in at 

 the aperture. These teeth are nearly equidistant 

 from each other and from the extremities of the la- 

 brum. The other pair is placed so far within the 

 shell as not to be seen at all from the aperture. 



I found several specimens in a humid situation at 

 Harrisate.
