HALIOTTD.E. 430 



Species of Broderipia. 



Cumingii, A. Adams. rosea, Brod. 



iridescens, Brod. 



Genus ANATOMUS, Montfort. 



Operculum thin, horny, sub-spiral. 



Shell minute, spiral, heliciform, depressed, widely um- 

 bilicated ; spire short ; aperture sub-orbicular, not pearly 

 within ; outer lip with a narrow fissure or slit. 



Sy?i. Scissurella, D'Orb. 



E.V. A. crispatus, Fleming, pi. 50, fig. 4. 



The animal of Anatomus has not hitherto been accurately 

 observed, so that the systematic position of the genus is 

 rather doubtful. The aperture of the shell is not nacreous 

 or pearly internally ; the fissure in the outer lip is some- 

 times incomplete. Montfort, speaking of his A. Indicus, 

 observes that it inhabits the Sargassa or Gulf-weed.
