(Read before the Society, June 14th, 1899). 



By the death of Sylvanus Hanley conchological science has lost one 

 of its most careful and excellent students. As far as the writer of 

 these remarks can judge, no conchologist with whom he has been 

 personally acquainted has devoted more care to his work than Mr. 

 Hanley. Thoroughness being his motto, it results that his mono- 

 graphs, produced forty to fifty years ago, still remain standard works 

 upon their respective subjects. His writings upon mollusca consist 

 of separate works, monographs of special groups, and descriptive 

 papers : — - 

 (A). Separate Works. 



1841. Exotic Conchology, ed. 2. 



1842. The Conchologist's Book of Species. 



1 842-1856. An Illustrated and Descriptive Catalogue of recent 



Bivalve Shells. 

 1848-1853. A History of British Mollusca and their Shells. 

 (Shell portion). 

 1855. Ipsa Linnaei Conch ylia. The Shells of Linnaeus, 

 determined from his Manuscripts and Collection. 

 1854-1858. The Conchological Miscellany. 



1 870-1 876. Conchologia Indica. Illustrations of the Land and 

 Freshwater Shells of British India. 

 (B). Monographs. 



1846. The Genus Tellina. ^ 



i860. The Family Nuculid*. \ I" Sowerby's ' Thesaurus 

 ,863. The Genus Solarium. J Conchyhorum.' 



(C). Descriptive and Miscellaneous Papers. 



(1). Twenty nine Papers in the Proc. Zool. Soc, 1842-1882. 

 (2). Four Papers \x\Journ. Linn. Soc, 1859-1885. 

 (3). Two Papers in the Annals and Mag. Nat. Hist., 1868 and 

 1885. 

 Of his separate works, that on British Mollusca, written in conjunc- 

 tion with Professor Edward Forbes, is perhaps the most widely known. 

 Probably most readers of this journal are well acquainted with the 

 character of that work, and consequently further commendation is 

 unnecessary. It still remains the finest work upon the subject although 

 written half-a-century ago. The ■ Ipsa Linnaei Conchylia ' was a most 

 important publication, dealing with a subject surrounded with many 

 difficulties. The amount of pains and research expended in the
