LINNEAN SOCIETY OF LONDOK. XXXVU 



and executors, of whom IMr. Van Voorst was one, by our Librarian, 

 IMr. Kippist, and by other Members of the Society, who were 

 desirous of paying this last sad tribute of respect. Since his death, 

 his extensive library of Xatural History books, and his valuable col- 

 lections of British Birds and Fishes have been sold by auction ; and 

 the latter have been thus transferred to the British Museum. But 

 his works will convey to posterity a faithftd picture of his distin- 

 guished merits as a naturalist ; while his portrait, by INIrs. Carpenter, 

 the result of a subscription among forty Fellows of the Society in 

 1839, will continue to adorn our Meeting-Eoom, and to recall to 

 the minds of oux FeUows the memory of a most valuable Member 

 of the Society, and of a thoroughly amiable, estimable, and ho- 

 nourable man. 



The titles of his multifarious papers are given at length, and 

 with but few exceptions, in the ' Bibliographia Zoologiae et Geo- 

 logise ' of the Ray Society, and amount to no fewer than seventy. 

 It is proper, however, that I should here enumerate his contribu- 

 tions to our own publications, which are as follows : —
