 summit acute; posterior extremity angular, disk with numerous 

 very regular, close concentric lines." (Conrad.)

 been lost or destroyed, and no others have been met with in any 

 of the more recent collections. The original specimen was only 

 about 2 mm. or a little less in width. The description given above

Remarks. The above is Conrad's original definition of the 

 species. The type specimen in the collection of the Philadelphia
