Historical Account of Testaceological }Friters. 213 



The student Avill find much useful illustration of the generic 

 characters of bivalves in the 6th volume of the Linnean Society's 

 Transactions; in which 



MR. WILLIAM WOOD 



has described and figured the hinges of such shells of that division 

 as are found in Great Britain.

 residence near the sea coast, has been enabled to make consider-

 with descriptions of, and various particulars relative to, many of 

 the animals of that order whose history was much less perfectly 

 known before. He has enumerated nearly 470 species ; upwards 

 of 100 of which had either not been described by any former au- 

 thor, or had noAV first been ascertained to be British. Sixteen 

 coloured plates accompany tlie work, on which are delineated 

 some of the shells described, but not figured by former writers, — 

 a few already known, which are necessarily introduced for the 

 sake of comparison, — and many first discovered by INIr. Montagu 

 himself; of the latter, however, about thirty are unaccompanied 

 by figures. This author adopts the Linnean system; but has de- 

 viated from it in placing many Linnean Helices under the genus
