On The Parasites Of The Lake Fish: Notes On The Structure And Life History Of Distoma Opacum, N. Sp., Henry B. Ward
Studies from the Zoological Laboratory: The University of Nebraska
This work was done while a member of the scientific corps sent out by the Michigan Fish Commission to begin an investigation of the biological conditions in the Great Lakes. The work in 1893 was carried on at New Baltimore, on Lake St. Clair. My thanks are due to the Michigan Board of Fish Commissioners for the many conveniences placed at my disposal in carrying out the investigations on fish parasites, of which this is one result. To Professor J. E. Reighard, director of the party, I owe much for his interest and hearty cooperation in all matters pertaining to …

A Preliminary Report On The Worms (Mostly Parasitic) Collected In Lakes St. Clair, In The Summer Of 1893, Henry B. Ward
Studies from the Zoological Laboratory: The University of Nebraska
In the work done on the fauna and flora of Lake St. Clair during the summer of 1893, the group of Vermes was entrusted to the writer. The following is submitted as a preliminary report on the ground covered, the material obtained, and the results of this branch of the work so far as they can be seen at this stage.
Excluding the Rotifera, which were studied by another member of the party, the Vermes are represented in fresh water by three great classes: the Plathelminthes (Flatworms), Nemathelminthes (Round or Threadworms), and the Annelida (Segmented-worms).

Studies from the Zoological Laboratory: The University of Nebraska
An important advance in the morphological and systematic knowledge of the Cestoda has been made this year through two papers published by Dr. C. W. Stiles, of the Bureau of Animal Industry. They command attention not only since they emanate from an American worker, but also by reason of the methods employed. Heretofore it has been largely true that tapeworms were identified by their hosts and by their general appearance, and hence no branch of systematic zoology has been more confused. The same form from different hosts was the recipient of as many different names, and even specimens from the …
