collections near Brainerd in Cass and Crow Wing Counties. In 



1894, under the direction of the U. S. Fish Commission, the writer 

 made colleetions in the lakes in the vicinity of Worthington, Heron 

 liake and some, small streams at Heron Lake, Wood Lake and the 

 Des Moines Eiver at Windom and Lake Washington near Mankato. 

 The same season, under the U. S. Fish Commisson, Mr. Woolman 

 and I made collections in the Lake of the Woods and took some ob- 

 servations on Lake Superior; also collections on the Upper Missis- 

 sippi in the region of Deer Eiver and Grand Eapids and on the St. 

 Louis Eiver and tributaries at Floodwood and Stony Brook. In 



1895, under the direction of the Natural History Survey, Mr. L. E. 

 Griffin and I made collections on the Western arm of Leech Lake 

 and its tributaries. I have made collections in the Minnesota and 

 Blue Earth Elvers and several lakes in the vicinity of Mankato 

 each season since the fall of 1891; considerable data and many 

 specimens have been collected in the region of Minneapolis at 

 various times; Prof. J. M. Holzinger of Winona has made a small 

 collection at that place and Prof. Woolman has collected at various 

 places in the northern part of the state and at various times but 

 the results of his later collections have not been published, so are 

 not included in the report. 



Mr. F. B. Sumner classified and catalogued a large number of 

 the specimens collected by the Natural History Survey but very 

 much of this material had not been opened after being sent in from 

 the field until it was examined for this report. The material and 

 notes of the above collections form the basis of this work. 



I here acknowledge my sincere thanks to Dr. B. W. Evermann 

 of the United States Fish Commission who, in addition to the loan 

 of many of the proof sheets of volume I. of the Fishes of North and 

 Middle America, has assisted in the identification of a number of 

 diflficult specimens and has offered many valuable suggestions; 

 also to Prof. Henry F. Nachtrieb, State Zoologist, for many favors 

 and directions in regard to the report.
