XVl FISHES OF ILLINOIS 



Besides the assistants already mentioned, especial acknowl- 

 edgments are due to Mr. H. Garman, assistant in the State 

 Laboratory and collector of much of our material during the early 

 years of the work; to Mr. A. J. Woolman, who, in 1903, made and 

 recorded measurements of many specimens of the commoner spe- 

 cies, and who, by his studies of the osteology of the Catostomidce 

 opened the way to improved generic definitions of Ictiohus and 

 Carpiodes; and to Mrs. Lydia M. (Hart) Green and Miss 

 Charlotte M. Pinkerton, who made, under the supervision of 

 the field ichthyologist, the colored drawings by which this report 

 is illustrated. Professor Frank Smith, Dr. C. A. Kofoid, Mr. C. 

 A. Hart, Mr. J. E. Hallinen, and Mr. E. B. Forbes have, during 

 their several periods of service on the State Laborator}^ staff, 

 added considerabh^ to our knowledge of the fishes of the state. 



It is impracticable to give the names of all outside the staff of 

 the State Laboratory who have been, from time to time, of mate- 

 rial assistance in the long course of this work, but this list of 

 acknowledgments would be seriously deficient without particular 

 mention of Dr. S. E. Meek, of the Field Museum, and Dr. Barton 

 W. Evermann, of the U. S. Fish Commission, both of whom have 

 been especially obliging in passing judgment on sets of specimens 

 of difficult determination, and in scrutinizing the tables of geo- 

 graphical distribution printed in the introductory part of this 

 report. It is a pleasure to acknow^ledge also our indebtedness to 

 a considerable number of careful and observant fishermen who 

 have told us much of the habits and behavior of our best-known 

 fishes. To Messrs. John A. Shulte, of Havana, J. P. Baur, of 

 the U. S. fisheries station at Meredosia, David Yeck, of Mere- 

 dosia, W. J. & H. L. Ashlock, of Alton, and Miles Newberry, of 

 Havana, we owe many facts concerning the life and economy 

 of our fishes which we should not otherwise have obtained. 



More than to any other, the Director is indebted to Mr. R. 

 E. Richardson — his colleague during three years in the prepara- 

 tion of this report — for indispensable service in the field, the 

 laboratory, and the library, and especially for the accumulation 

 and organization of material of all descriptions, for his critical 

 study of the collections, all of which were finally handled by 

 him, and for the preparation or revision of nearly all the technical 

 descriptions printed in this volume.

Director of Laboratory.
