115. The Pulraonates of the Pacific slope hf.vo not formed a special stndj- 

 with the writer of this lieport, as they were lalready in the abler hands of 

 Messrs. Binney, Bland, and other eminent Ti ansatlantic naturalists. The 

 opinions of Mr. Binney as to synonymy, &c., with descriptions of new 

 species and details of those previously known, were given in papers pub- 

 lished in the ' Proc. Ac. Nat. Sc. Phil.' as follows: — " Descriptions of American 

 Land Shells." Feb. 1857; "Notes on American Land Shells," Oct. 1S57, 

 May 1858, Nov. 1858, July 1859 : and also in the * Proc. Bost. N. H. S.,' 

 " Description of two supposed new species of American Land Shells," Apr. 

 1857. These are embodied in ' The Terrestrial Air-Breathing Molluscs of the 

 United States and the adjacent Territories of North America,' vol. iv., bj- 

 W. G. Binney, Boston, 1859. It was first printed in the ' Boston Journal 

 of Natural History,' vol. vii., and is intended as a Supplement to the great 

 treatise by his father, vols, i.-iii., on the same subject. It is impossible to 

 speak in too high terms of commendation of the manner in which this work 

 has been prepared and executed, and of the beautiful figures drawn by Otto 

 Kohler. The more mutui-ed views of the author were embodied in thn 

 * Check-List of the Terrestrial Gasteropoda of North America,' published bj 

 the Smithsonian Inst.. .Tune 18(J0, of which a second edition was soon issuea. 

 The species were divided into three series, — (1^ those of the Pacific coaiit,
