Obs. — Some ten years ago Dr. Cox sent me this shell, which I 

 returned to him as unknown. At that time I was unacquainted 

 with the genus. Since then I have possessed all the species, and 

 I take great pleasure in associating this fine shell with the name 

 of one who has done so much for the. science of conchology.
