Historical Account of Testaceological Writers. 213 



The student will 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. 



M. DUFRESNE. 

 From this writer we have some remarks on the genera of Tubi- 

 cinella, Cornula, and Balanus (of Lamarck), with admirable figures 

 of Coronula Balcenaris and Tubicinella, in the Ann. du Museum. 

 The communication is entitled " Notice sur les Balanus." 



The last writer whom we have to record in this historical ac- 

 count is 



GEORGE MONTAGU, ESQ., 



who, by indefatigable perseverance in his researches, and by a long 

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

 able additions to the British Testacea, and to gratify the zoologist 

 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 now first been ascertained to be British. Sixteen 

 coloured plates accompany the 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 Mr. 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 



Turbo.
