334 JOURNAL OF CONCHOLOGY. 
Rev. J. W. Horsley exhibited, on behalf of Mr. A. G. Stubbs, a very fine 
series of Helix virgata from Tenby. Mr. Cooper showed specimens of 
Cardium edule from Tilbury and Southwold to illustrate the influence of 
fresh water on the shape and texture of the shell. 
MEETING, DECEMBER Ioth. 
Held at 2, Craven Hill, W., by invitation of Mr. S. J. DaCosta, who 
very kindly exhibited a portion of his very fine collection. We particularly 
noticed the exceedingly good series of Bu/zmus and its allies (chiefly Central 
American) comprising several types and a number of rare shells. Also 
worthy of note were a fine series of West Indian He/zces and a beautiful set 
of Cochlostyle. A drawer full of brilliant Amphidromz was much admired, 
and so was the excellent set of Of7sthostoma. There were also some of the 
curious mollusca from Lake Tanganyika. Among the marine shells, some 
gorgeous species of Pecfew attracted attention. The Cyfr@e@ also were 
choice, and there was a very pretty set of Prexofoda. One evening was 
quite insufficient to see all the rarities Mr. DaCosta possesses.

BIBLIOGRAPHY. 
(LIMITED TO WORKS RECEIVED BY THE SOCIETY’S LIBRARIAN), 
The Collector’s Manual of British Land and Freshwater Shells, 
by LioneL E. ApaAms, B.A. Second edition. Taylor Bros., Leeds, 
1896. 
That a second edition of Adams’ excellent manual has been called for is 
a gratifying testimony to the value and usefulness of the work. For the re- 
issue, the text has been almost entirely re-written and brought fully abreast of 
the day, and the work now forms a handsome volume, containing 214 pages 
of text and eleven plates, the frontispiece being a beautifully-executed 
collotype plate, with enlarged and strikingly-pourtrayed figures of correctly- 
identified types of the British species of Pes¢d@éum. Anyone who has laboured 
to separate the various species of this puzzling group of shells, will appre- 
ciate the real help furnished by these large and exquisite representations. 
Nine plates are devoted to the presentation of faithfully-coloured figures of 
all the British species, which can hardly fail to greatly aid the identification 
of doubtful shells, while Plate XI. contains a series of instructive figures 
explanatory of the more usual terms employed in connection with the animal 
and shell. The text may be broadly divided into an introductory part, a 
descriptive and systematic part, and a concluding section, dealing with the 
comital distribution of the various species. The introductory chapters are 
chiefly devoted to a concise yet clear and interesting description of the most 
successful methods and appliances for collecting, and an account of the most 
suitable and most modern systems to be adopted for the preparation, preser- 
vation, arrangement, and display in the cabinet of the animals and their
