been neglected through lack of acquaintance with them, but for 
such omissions no one will feel greater regret than the writer. 
The works actually consulted, and which will be found of 
service to all students of the local mollusc fauna, are the 
following: 
'The Mollusca of the Chicago Area," by F. C. Baker, pub- 
lished in two parts as Bulletin No. Ill of the Chicago' Academy of 
Sciences. This very complete monograph, with its excellent half 
tone illustrations, covers nearly all the species found around 
Milwaukee and well serves the needs of the local student. In it 
are given full directions for collecting and cleaning shells, a 
glossary of terms, and other helps. 
The Smithsonian "Miscellaneous Collections," including 
Binney's "Land and Fresh Water Shells of North America," in 
Vols. VII and VIII, Tryon's "Monograph of the Strepomatidae," 
in Vol. XVI, and Prime's "Monograph of the Corbiculadse," in 
Vol. VII. Binney's "American Land Shells" is a revision of a 
portion of the above. 
Pilsbry and Johnson's "Land Shells of America north of 
Mexico," a classified check-list with localities, which costs twenty 
cents. 
Simpson's "Synopsis of the Naiades," published as Proceedings 
No. 1205 of the U. S. National Museum, is a complete systematic 
and synonymic catalogue of the Unionidae and allied forms. 
Tryon's "Manual of Conchology," a monographic descriptive 
work appearing annually, includes at present our land shells. 
"The Nautilus," the official American conchological journal. 
Condensed lists of the material which forms the subject of this 
paper have recently appeared in its pages. 
All of the above are available in the public library of the city, 
or in the library of the museum. In addition, the writer has had 
recourse to Vols. 1 to 4 of the American Journal of Conchology, 
Gould's "Invertebrata of Massachusetts" (Binney's reprint), 
DeKay's "Mollusca" in the New York State Natural History 
series, Call's "Mollusca of Indiana," Hartman's "Conchologia 
Cestrica," and certain bulletins of the Smithsonian Institution. 
Bryant Walker's "Mollusca of Michigan" ought also to be of 
assistance to the Wisconsin collector. 
In the lists which follow, no attempt has been made to put 
forth a scientific classification of the species, as that is not germane 
to the purpose of the paper. The record is primarily that of 
faunal distribution, and the various forms have therefore been 
grouped for convenience as "land shells," "fresh water univalves"
