The principal characteristic of this species is the 



thickened festooned growth of the side claws, and the 



safi'ron-yellow eoluiu-ing of the shell in its far interior. It 



was first described and tigured by Chemnitz, but he faile<l 

 to name it in accordance mth the recognized form of no- 

 menclature founded by Linnasus.
