670 REPORT 1863. 



trom the extreme north, to Mazatlan ; (2) those of eastern N. A., from the 

 boreal regions to the Rio Grande ; (3) those found in Mexico, to which sixteen 

 from the first series are added. The freshwater Pulmonates are catalogued 

 by the same most industrious author, in the ' Check-List of the Fluviatile 

 Gasteropoda of N". America,' which contains the Melaniadce, Paludinidcr, 

 Ampullariadce, Valvatidce, and Limnceidce ; the West Coast species being dis- 

 tinguished by the letter W, and the Mexican by M. Mr. Binney next under- 

 took a monograph of the Paludinidce, &c., the proofs of which were widely 

 distributed in 1862. Afterwards, assisted by the extensive series of speci- 

 mens received from the Smithsonian Museum, and with access to those of 

 the principal public and private collections in the U. S., and with the benefit 

 of Say's types preserved in the Acad. Nat. Sc. Phil., he prepared a preliminary 

 synopsis of the Limnceidce, with full synonymy, proofs of which were issued by 

 the Smithsonian Inst., May 4th, 1863. Last of all, under date Dec. 9, 1863, 

 the Smithsonian Inst. has distributed proof copies of a complete * Synopsis 

 of the Species of Air-Breathing Molluscs of N. A., as eliminated from their 

 synonyms by Mr. Binney'*. Of all these works the author not only sent the 

 earliest slip -proofs to assist in the preparation of this Report, but in several 

 instances took the pains to write separately what related to the W. coast, 

 and even sent the manifold-duplicate of part of the printer's copy. It is not 

 considered necessary to tabulate each of these publications separately, as 

 they can easily be obtained by post, on application to Professor Henry, 

 Washington, B.C. The following list embodies (1) the classification and 

 nomenclature of Dec. 9th, 1863; (2) the synonymy as given in previous 

 synopses ; and (3) the localities and authorities supplied by Mr. Binney in 

 MS. The following reservation requires attention : " As a mere proof, 

 which will undoubtedly receive many corrections, this list should not be 

 quoted as authority, or referred-to as a published work."

Nat Hist N. York,' Oct. 1863. In an addendum, he gives a list of the Pacific species, 

 with an account of two "genera" not represented in the eastern division. Mr. Binney 

 continuing Mr. Bland's labours, issues the species for the most part in the trinomial 

 nomenclature, which now appears to be taking the place of the Linnean binomial system. 

 No attempt is here made to review the work, as the writer felt justified in doing with 

 reference to marine shells ; the only alterations made consisting of corrections m some of 

 the citations with which he happened to be more familiar.
