a 
670 REPORT—1863. 
from 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 Melaniade, Paludinide, 
Ampullariade, Valvatide, and Limneide ; 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 Paludinide, &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.8., and with the benefit 
of Say’s types preserved in the Acad. Nat. Sc. Phil., he prepared a preliminary 
synopsis of the Limneide, 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, D.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.”

* The first Transatlantic attempt to revise the genera of N. A. Helicide was made by 
Mr. Bland, in his “ Remarks on Classifications of N. A. Helices by European authors, 
and especially H. and A. Adams and Albers,” printed in the ‘ Annals of the Lyceum of 
Nat. Hist. N: York,’ Oct. 1863. In an addendum, he gives a list of the Pacifie 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 in some of 
the citations with which he happened to be more familiar.
