172 THE BERMUDA ISLANDS. 



Jldeorbis. 



A number of small specimens, obtained from the sands of 

 the north shore, which closely resemble the Helix (Adeorhis) 

 cydostomoides of Pfeiffer, from Cuba. The spire in the Bermu- 

 dian form is, however, practically wanting. 



Soalaria clathrus, L. 



S. lamellosa, Lam. 



S. coronata. 



South Carolina, W. Indies, Europe. 



lanthina oommnnis, Lam. 



Florida. 



Common on both shores of the islamls, and largely associated 

 with Spirula Peronii. Its occurrence away from the immediate 

 shore-line is, doubtless, due to wind deposit. 



lanthina g^lobosa, Swn. 



Florida. 



This species is apparently much less abundant than the 

 preceding. 



TuTTitella, sp. ? 



Several fragments of a species which Ihave been unable to 

 determine. 



Fetaloconclius, sp. ? 

 ? Vermettts Knorri, Say. 



.? Ferme^MS radicuia, Stimpson. 



Siliqnaria (Tenagodus) ruber, Schum. 



I give this species as a member of the Bermudian fauna on 

 the authority of Morch. 



CaeoamFloridanam, Stimps. 



Florida. 



A single specimen from the sands of the north shore. 



Caecum termes, u. sp. 



A number of specimens obtained through the kindness of 

 Miss Peniston,
