About 200 specimens of shells from California and the 

 Sandwich Islands were purchased of Mr. Thomas Nuttall, by 

 whom they were collected, and a few years later (1861) 368 

 additional specimens were received from Mr. Nuttall's executors. 

 A list of his collection was published by T. A. Conrad in the 

 Journ. Acad. Nat. Sci. Philad. vii. pp. 227-268 and P. P. Car- 

 penter in the Proc. Zool. Soc. London, 1856, pp. 209-229. 



1855-56. 



An important series of 1524 shells from the Solomon, Fiji, 

 and Kermadec Islands was received from the Lords of the 

 Admiralty, having been collected by Mr. John Macgillivray 

 during the voyage of H.M.S. Herald. 



1856. 



A collection of Mollusca, comprising 3941 specimens, 

 obtained by Mr. J. Gwyn Jeffreys on the coast of Piedmont, and 

 a second series of 2426 Mediterranean shells were this year 

 obtained by purchase from R. Damon, of Weymouth, and 

 M. Parzudaki respectively. 



At this time and during the following years Mr. Searles V. 

 Wood presented his valuable collection of Crag Mollusca, com- 

 prising over 4000 specimens, to the Zoological Department. 

 This collection, since transferred to the Geological Department, 

 formed the material upon which Mr. Wood based his " Mono- 

 graph of the Crag Mollusca," published in 1848-1856 (2 vols. 

 pp. 550, 52 plates). 



1857. 



The " Mazatlan Collection " of Mollusca was this year pre- 

 sented by Dr. P. P. Carpenter, who prepared a catalogue of it 

 which was published by the Trustees the same year. 692 

 species are enumerated or described, of which 215 were new. 

 The total number of specimens in the collection amounts to 

 about 8800. They were collected in 1848-50 by Mr. Frederick 

 Reigen, and as a geographical series are of considerable im- 

 portance.
