ZOOLOGICAL LITERATURE. 
concerning the immigration (or rather importation) of this 
mollusk which had come to his notice^ but the paper was not pub- 
lished until this year (Zool. Gart. Frankf. 1865, pp. 50-59, 89-97). 
Dreissena is, according to Hr. Merian (1. c.), accompanied by 
Neritina fluviatilis in the Upper Rhine, where it never occurred 
before. The Recorder is enabled to confirm this by a communi- 
cation from Prof. Braun, who says that it was not found in the 
Rhine near Carlsruhe some twenty years ago. 
Hr. Kreglinger, in his List of the Shells of Baden, states that 
Helix austriaca (Mhlfld.), a species peculiar to Eastern Europe, 
was once found alive in a garden at Carlsruhe, having been evi- 
dently imported by some accident. On the other hand, he 
mentions Margaritana margaritifera (L.) as oceurring near 
Heidelberg, and as originally imported.^^ This, we think, is 
also the case with Clausilia i/a/a, var. hrauni (Charp.), which has 
been long known to occur in one locality of the warmest part of 
the country, Weinheim, where an excellent wine is grown. 
B. Bibliography. 
Binney, W. G. Bibliography of North American Conchology 
previous to the year 1860, prepared for the Smithsonian 
Institution. Part I. American authors. Smithsonian 
Miscellaneous Collections, vol. v. Washington, 1864, 8vo. 
The object and contents of this extensive publication may be 
given in the authors own words : — It is intended to give a full 
account of the writings of American conchologists generally, 
separated into three sections : A. American descriptions of 
North American mollusks; B. American descriptions of foreign 
mollusks j C. Deseriptions of foreign species by American au- 
thors in foreign works. It will be seen that each separate work 
or paper on the recent conehology of North America is taken 
up, its title and date given, its authors name, and a list of species 
therein described, or in any important manner refet'red to, indi- 
cated, together with their synonymy, locality, and the volume, 
page, plate, and figure relating to them. For their value as con- 
tributions to our knowledge of geographieal distribution I have 
also quoted all the loeal lists of speeies without deseriptions. The 
geographieal limits to whieh I have confined my work are the 
whole continent of North America, including Greenland and the 
Aretic regions on the north and in the south the Mexican 
States of Chiapas and Tabasco, excluding the fauna of Panama 
and the West Indies.'^
