We are inclined to believe the Doftor, as well as others, 

 have confounded this with the young of the H. riifefccns, 

 AV'hich is frequently hirfute, and not uncommonly placed 

 in cabinets for this fpecies ; but we before remarked in 

 the defcription of that (hell, that the fliape and um-

 any one. 



It rarely exceeds three-eighths of an inch in diameter 

 at the bafe, and is not a quarter of an inch in height.
