EDITOR'S NOTES. 



It may not be out of place to direct attention to several changes which 

 appear in this, the fii'st part of volume x. 



Firstly, we oflfer a hearty welcome to Mr. H. Howard Bloomer, Mr. 

 G. K. Gudc, and ^Ir. Henry Suter, whose names have been added to the list 

 of editorial colleagues. All are well-known malacologists, and for many years 

 have been active and generous supporters of the Journal. 



As to the Journal itself, we have slightly increased the amount of 

 printed matter on each page containing original articles, and the notices 

 of Current Literature, Notes, etc., are printed in a larger type than 

 liitherto. 



We have recently received new editions of the well-known and nseful 

 catalogues of works and pami)hlets treating of the Mollusca, issued by 

 Messrs. B. Friedliinder und Sohn (witli nj)wards of .'i,000 titles) and that of 

 Mr. W. Junk (l,7():i titles), both of Berlin.
