MISCELLANEOUS NOTES. 

 The late C. R. Thatcher. — -Our readers will regret to 

 learn of the recent decease of this well-known conchological 

 collector. Several months ago he started on a five years' collecting 

 tour, and had made the most careful arrangements for deep-sea 

 and shallow dredging. Attacked suddenly by fever he died a 

 few days after reaching Shanghai. His loss is almost irreparable 

 and his abilities were great. To his indefatigability we owe the 

 discovery of the unique Thatcheria inirabilis (Angas, P.Z.S.), 

 which will now be his most enduring memorial; also oi Dclphiiiu- 

 lopsis Lesourdt, described by Bryce Wright in the French Journal de 

 Conchyliologie. Many other interesting forms are due to his labors. 



The Formation of Conchological Libraries. — Such of 

 our readers as are engaged in the formation of a special library 

 will derive considerable assistance from the Book-Catalogues 

 poriodically published by Mr. Wm. Wesley of London, and 

 Messrs. R. Friedlander & Sohn of Berlin. These catalogues are 

 unrivalled in their comprehensiveness, and the one for British, 

 the other for continental literature, will be of great assistance- 

 The Berlin firm have also commenced the issue of a fortnightly 

 publication under the title of 'Naturae Novitates,' which is intended 

 to give immediate information of the publication of scientific 

 memoirs of all kinds and in all languages.
