in the Museum of Natural History of the University of Illinois
(Mollusca and associated animals).
  My thanks are due a large number of people for assistance in
the field work or in the subsequent study of the material. Chief
among these are Professor Chancey Juday of the Wisconsin
Geological and Natural History Survey, who made the study pos-
sible; -and, the Conservation Commissioners of the State, through
Mr. I. H. Bloomer, in charge of the Fish Hatchery, who gave every
possible facility for advancing the work. Mr. Hall and Mr. Apel,
hatchery assistants, also granted many courtesies which greatly
assisted in the success of the undertaking. To Mr. Clyde B. Terrell,
of Oshkosh, the owner of the interesting aquatic farms on Lake
Butte des Morts, the writer is greatly indebted for assistance in
studying the fauna of that lake.-
  The sincere gratitude of the writer is especially due those spe-
cialists who cheerfully gave of their time for the identification of
groups of animals in which they are experts. The large amount of
material sent could not but have been somewhat of a burden to
classify, and I am sure that the feelings of other workers in
ecological subjects are expressed in the statement that the value
of their assistance cannot be overestimated. The following persons
assisted in this work of identification: Dr. Bryant Walker, De-
troit, Mich., various mollusks; Dr. V. Sterki, New Philadelphia,
Ohio, Sphaeriidae; Mr. Calvin Goodrich, Detroit, Pleurocera; Dr.
Ruth Marshall, Rockford College, Rockford, Ill., Acarina; Dr. J.
Percy Moore, University of Pennsylvania, leeches; Dr. J. G. Need-
ham, Cornell University, acquatic insects; Dr. Cornelius Betten,
Cornell University, Trichoptera; Dr. Paul S. Welch, University of
Michigan, aquatic Lepidoptera; Professor Frank Smith, University
of Illinois, Oligochaete worms and sponges; Dr. C. P. Alexander,
University of Illinois, aquatic insects; Dr. Wm. Trelease, Univer-
sity of Illinois, certain plants; Miss Ada L. Weckel, Oak Park, Ill.,
Amphipoda; Mr. Waldo L. Schmitt, U. S. Nat. Mus., Washington,
D. C., Isopoda; Prof. Chancey Juday, University of Wisconsin,
