58 BIBLIOGRAPHY, 
these animals occupy twenty-five pages. Amongst them we notice the 
classic treatises of Kiener, Reeve, Sowerby, and Tryon, along with a large 
number of tracts bearing on the fauna of different regions ; for example, 
twenty-six works are catalogued bearing on the mollusca of France alone, 
and other countries are nearly as well represented. 
In the second section of the cata'ogue, the works are arranged alpha- 
betically, according to the author’s name, the titles being contracted so that 
two columns may go in a page, so that if a particular work by a particular 
author is sought it can be very readily found. At the end is an index of 
subjects by which reference can be instantly made either to the shelves of 
the library or to pages of the catalogue. We are sure that all working 
naturalists in Manchester and the neighbourhood will find this catalogue a 
valuable help in their studies. 
The Journal of Malacology, Vol. IV, No. 1, March 30th, 1895. 
Edited by Wilfred Mark Webb, F.L.S., and Walter E. Collinge, F.Z.S. 
The first number of this magazine, already so well-known to all students 
of the mollusca, under the new joint editorship of Mr. W. M. Webb and Mr. 
W. E. Collinge, augurs well for its future, and we would wish to express our 
sincere congratulations and best wishes for its success in every way. 
The principal original articles are six in number: two being devoted to 
our native oyster ( Ostvea edulis) under two different aspects. One is by Mr. 
W. M. Webb, on the di-myarian stage of this bivalve, with three explana- 
tory diagrams, and one full plate, which would tend to prove the existence 
of a posterior adductor muscle at one period of its existence ; the other, by 
John C. Thresh, deals with oysters as disseminators of disease, especially 
cholera and typhoid fever, when the beds are liable to sewage contamina- 
tion. The eating of oysters procured from such sources is proved to be 
attended with much danger, and the earlier attention is called to the 
matter the better. 
There are descriptions of Zzmax hedleyz sp. n. from Ireland, and a note 
on Amaha parryi sp. n. from Santa Cruz, Teneriffe, by Mr. Walter E. 
Collinge. Mr. George Bailey has observed the process of fission in Cheto- 
gaster, a worm parasitic on Limnea stagnalis, but his paper would have 
been more complete if he had referred to Lankester’s work on the subject ; 
and, lastly, Mr. Edgar A. Smith unearths the prior names J/orio (Mont- 
fort) and Lambideum (Link.) which will have in future to supersede the 
well-known terms Cass¢darza (Lamarck) and Oziscéa (Sowerby). We are 
sorry for this, but it is well to have the question settled, once for all, and 
doubtless many other well-known names will in time have to give place to 
others waiting for a priority-student to unearth. We may point out that 
many generic names are in a like predicament, and we fear the classification 
of these will be a most difficult, and in some cases almost hopeless, matter. 
Some interesting notes on mollusca, both recent and fossil follow, and the 
number concludes with the usual full and clear tabular arrangement of cur- 
rent literature.
