Copies of published local catalogues, especially if not 

 readily procurable, are desired, either as a loan or in exchange.

 of the various species, and for this reliance will have to be 

 placed upon published lists as well as actual specimens. 



Foreign correspondents would therefore confer upon the 

 projectors a favour by forwarding specimens from as many 

 localities as possible, and by presenting copies of local cata- 

 logues, many of which are not usually of easy access. In all 

 cases it should not be forgotten that 



Precision and Accuracy 

 are indispensable in the labelling of specimens with locality, 

 date and other particulars, and that nothing is more to be 

 deprecated than looseness, carelessness and inaccuracy with 

 regard to such information. The 



Synonymy and Bibliography 

 will be as full and complete as possible and as far as practicable 

 from personal verification of the leading citations. As this will 

 involve an extensive examination of the literature of the subject 

 the projectors would be pleased to be favoured with the loan 

 of works to which they have not access (from their scarcity or 

 otherwise). The editor of the " Journal of Conchology " will 

 also be glad to enter into exchange for the Proceedings of 

 Societies which publish conchological matter. The 



Biological Aspect 

 of the subject will receive its due share of attention. Full 

 •descriptions will be framed, in which both the molliisk and 

 its shell, its internal anatomy, its jaws and teeth, will be fully 

 ■described and figured, and its embryological development so far 

 as known, will be treated of. In dealing with these important 

 matters it is hoped to secure the assistance of those who devote 

 attention to microscopical and embryological investigation. In 

 addition to the technical description it is proposed to include 

 remarks on diagnosis and affinities, briefly indicating the chief 

 points to which attention should be paid in discriminating the 

 form from its allies. The species in its
