Historical Account ofTestaceological 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. lie 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,
