This is one of the best, if not the very best compendium of 

 Conchology ever published, and as such we earnestly commend 

 it to the patronage of our subscribers. The amount and variety 

 of information upon the subject here gathered together is extra- 

 ordinary, and reilects great credit on the assiduity and learning 

 of its author and compiler.

OBITUARY. 



Joshua Alder. 



This veteran Conchologist died on January 21st, 1867. He 

 was the author of numerous papers upon the Mollusca and 

 Zoophytes of Great Britain, including a beautiful and valuable 

 monography on its Nudibranchiate Mollusca, written in conjunc- 

 tion with Mr. Albany Hancock, and published by the Ray 

 Society. Mr. Alder was a most excellent collector, and very 

 much endeared to English naturalists by his unassuming manners 

 and the kindly assistance always afforded to those engaged in 

 pursuits similar to his own.
