MOLLUSCA. 
7, North America, 
W. G. Binney has published a new and comprehensive treatise on the 
North American terrestrial Mollusks as vol. iv. of Bull. Mus. C. Z. ; it 
contains descriptions, synonymy, indications of localities, and woodcuts 
of all known species, very often also woodcuts of the jaw and radula, and 
in a separate volume, 74 copper-plates representing the shells, and also a 
living animal of each genus (reproduced from the work of the author’s 
father, Amos Binney), and 16 new lithographic plates representing the 
genital organs, and jaws and teeth of the radula on a larger scale than the 
woodcuts. The whole is brought up to the level of the state of know- 
ledge in January, 1878, and the same may be said with regard to the 
introduction, which treats of the habits and faculties, geographical dis- 
tribution [Zool. Rec. xii. p. 143], and special anatomy of these animals. 
The work contains 283 species, distributed in 51 genera or subgenera, and 
6 families. 19 species are also European, 11 of them evidently intro- 
duced ; 8 on the contrary circumpolar, viz., Zonites nitiduSy viridulm^ 
fulvuSi Ferussacia suhcylindrioa [luhricd], Pupa muscorum^ Acanthinula 
harpa, Vallonia pulchella^ and Punctum pygmcBum.
