Inhabits 



The above-cited two figures were intended by Martini for the 

 same shell, though Gmelin refers only to fig. 209, which has 

 very much the appearance of a young Cypraea, and Schrei- 

 bers has arranged this species as a variety of Gmelin's Bulla 

 ovata, which is the young of Cyprcca Mauritiana. Fig. 210 

 has more the appearance of a Bulla, and is shaped a little 

 like B. Naucwn. Martini describes it to be an inch and a 

 half long, and to have the outer lip replicated, serrated, and 

 slightly toothed on the inside, but it appears to me to be a 

 very doubtful species. 



aperta. 1.4. Shell somewhat rounded, pellucid, 

 slightly striated transversely, and the aper- 

 ture comprising almost the whole shell.
