Remarks, — This pretty little species of Cyclostoma was sent by Mr 

 Wood to Mr T. R. Peale, to whom I owe the opportunity of describing 

 it. Its transparency and numerous brown spots distinguish it at once 

 from all other species with which I am acquainted. In the individual 

 before me, there is a second obscure carination above that on the mid- 

 dle of the whorl. In others this may be found to be more distinct 

 or entirely wanting.
