 the variety is from New Holland. 

 Shell from three to five inches long, and about three fourths as 

 broad, thin, rather brittle, of a greyish, pale brown, or fawn 

 colour, longitudinally undulated with white spots ; the ribs 

 formed by the shallow transverse grooves, of which there are 

 about twenty on the body-whirl, are more or less flat, and 

 the pillar is umbilicated. Dr. Solander, for his B. maculo- 

 sum, has referred to Seba's fig. 16, and it appears to be 

 only a variety of this species. 



POMUM. 4. Shell ovate, with transverse convex 

 ribs ; pillar wrinkled, aud the outer lip tooth- 

 ed and thickened.
