A SUMMARY OF

 - 1901. 



Extract from Preface. 



It has been a constant source of difficulty for many }'ears 

 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 furnish- 

 ing 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 fiir M alakozoologie,' 

 'Annals and Magazine of Natural History', &c. — no forms 

 will be included which are not, in the strictest sense. Molluscs. 



The general arrangement is that of the 'Zoological Record.'
