Some land- and freshwater species from Puerto Montt, in Southern Chile, 
are described by the Kecorder, Mai. liliitt. xvi. pp. 216-218. 
7. North America, 
The inoperculated land- shells of North America have been 
worked out by Binney and Bland in their work, ^ Land and 
Freshwater Shells of North America,'’ Part I. The descriptions 
are chiefly copied from Binney’s larger work on the same sub- 
ject, published some years ago j but the more recently dis- 
covered species are also included, ^Hhe whole subject beiug 
brought down to January 1868/^ Each species is figured by a 
woodcut ; very often also the jaw or lingual dentition. For 
classification, the second edition of Albers has been followed ; 
the doubtful species, and those falsely quoted as North American, 
are carefully indicated. 
The West- Coast land-shells are once more the subject of a paper published 
by F. G. Cooper, Am. Journ. Conch, v. pp. 199-215. It contains, besides 
the discussion of various questions of nomenclature and classification, also 
many valuable statements concerning the geographical distribution of some 
species ; the author points out that the neighbourhood of South-east Bay is 
very rich in species, northern and southern forms meeting here in larger 
number than elsewhere. Some European species occur in Unalaschka, 
where they were found by Mr. Harford, viz. Vitrina ^x-Uacida P, Comdus 
fulvus?, Patula ruderata?, and Zua suheylindnea [luhrica, Miill.], pp. 200, 
202, 216.

A large number of American Melaniidce and Unionidee, described and

b. Famia of Brackish Watet'. 
The occurrence of several marine and freshwater mollusks, and their 
diminutive size, in the Baltic^ are mentioned by N. Saenger in the Russian 
Journal mentioned above (p. 517). At Revel Mytilus edulis and Tellina [pro- 
bably baltica, L.] occurs to the depth of 100 feet and more. Comparative 
measurements of specimens of several shells from the German Ocean and 
Baltic are given.
