Excerpt from Copepod Parasites of Fresh-Water Fishes and Their Economic Relations to Mussel Glochidia The specimens and other material were derived from several sources. First, the work of the biological station involves the handling of large numbers of fish, and several of the regular staff, notably Mr. H. W. Clark, Mr. T. Surber, and Dr. A. D. Howard, have saved such parasitic copepods as they found while examining the gills for glochidia. These were generously turned over to the present author, who had also accumulated a large number of Specimens during the surveys of the mussel fauna of various regions of the United States under the auspices of the Bureau of Fisheries. These collections were augmented during the present investigations by a careful examination of all the preserved gills of fish in the possession of the biological station, of the gills of live fish caught by the regular seining crew or brought to the station for glochidial infection, and of a large number of dead fish caught by local fishermen.
