Named in honor of mine host Mr. Geo. A. Bishop, Supt. of Public 

 Gardens, Hamilton, Bermuda. 



As to Siplionaria, Verrill has described in tiie "Transactions of 

 the Conn. Academy of Science," a species called S. heirica. So far 

 as is known, only one specimen — the type — is in existence. This 

 was taken at Bailey Bay on the north shore. AVe collected over 

 three pints of *S'. alternata Say, and found many of the var. hrunnea 

 Hanley, also two others. 



2. Shell small (size 16x13 mm.), blackish, opaque opalescent, 

 rare, Hungry Bay, south shore (Fig. 15). Var. opalescens n. v. 



3. Intermediate in size and coloration between bruniiea and opal- 

 escens. Very thin, translucent, always distinguished by radial black 

 lines from apex to margin, covering the whole or a part of the inner 

 surface. Common on the south shore at liigh-tide mark (Fig. 16). 



Var. intermedia n. v. 



There are undoubtedly many marine species which might be 

 added to the published lists of Dall, Heili)rin, Verrill, and others; 

 but the great ditficulty just now is to eliminate equivalent nomencla- 

 ture. I have not seen records of the following species taken by us 

 in Bermuda : 



Acmaea punctnlata Gmel. Ocinebra intermedia Ads. 



Anachis catenata Sowb. Nassa consensa Rav. 



Alabina adamsii Dall. Natica livida Pfr. 



Asaph's deflorata Linn. Nitidella cribraria Linn.
