Extract from Preface. 



It has been a constant source of difficulty for many years past to 

 ascertain what work has been done by our predecessors relating either 

 to a special genus or to some faunal district ; with the idea of 

 rendering some assistance to students, the present work has been 

 undertaken. With a view to furnishing an index to the periodical 

 now dealt with, the few species described in its pages which do not 

 belong to the Mollusca have been included ; in future work, however 

 — and it is hoped, if sufficient support be forthcoming, to deal with 

 other periodicals such as the Zeitschrift fur Malakozoologie, Annals and 

 Magazine of Natural History, etc. — no forms will be included which 

 are not, in the strictest sense, Molluscs. 



The general arrangement is that of the Zoological Record.
