THE FRESH-WATER FISHES OF MEXICO NORTH OF THE ISTHMUS OF TEHUANTEPEC, MEEK 1904

THE FRESH-WATER FISHES OF MEXICO NORTH OF THE ISTHMUS OF TEHUANTEPEC BY SETH EUGENE MEEK, PH.D Assistant Curator of Department ZOOLOGICAL SERIES VOL V CHICAGO, U I S A ^Wt/^D SEP 23 1904 PREFACE the The following paper is based largely on two collections of fishes, first being made by the writer and Mr F E Lutz, of the Carnegie Station for Experimental Evolution, Cold Spring Harbor, in the spring of 1901, and the other by the writer during February, March, April, and May, 1903 Through the courtesy of Dr Barton W Evermann, assistant in charge of Scientific Inquiry, United States Bureau of Fisheries, I have had at my disposal two small collections made by Mr E W Nelson, one from the Rio Balsas and the other from the Rio Soto la Marina Dr W L Tower, of the University of Chicago, also placed at disposal a collection of fishes made by him at Rio Verde, San Luis Potosi In January, 1903, in Washington, D C., Dr Richard Rathbun, Assistant Secretary of the Smith- my sonian Institution, and Mr B A Bean, Assistant Curator of fishes U S National Museum, permitted me to examine a large collection which formed a portion of the Mexican fish exhibit at the Columbian I have included only a small portion of this collection in Exposition the following given list because of the doubtful character of the To have included the entire collection localities would have very much confused our study of geographical distribution An account of the collection made by Mr F E Lutz and myself is published in Vol III of the Zoological Series of the Field Columbian Museum, Pub 65, pages 63 to 128, plates 14 to 31 The results of the second expedition are (1903) included in this paper For assistance while making the collection of fishes in 1903, wish, to indebtedness the my R Hudson and Mr A V Temple, on behalf of the Museum, to acknowledge Mr C following gentlemen: of the Mexican Central R, R W Harvey, of the Mexican M Ames, and Mr A Joy, Pegram, & Pacific R R.; Mr W B Ryan and Mr Newbury,

Sciences, Philadelphia Dr Theo Gill, Washington, D C., has kindly called my attention to a few important references which I would have otherwise omitted Hon Geo M Bowers, United States Commissioner of Fish and Fish- Museum, Dr D W Fowler eries, S in the kindly loaned the Museum for use in illustrating this work thirty-one original drawings of fishes Four other drawings were kindly To Dr Evermann I am under loaned by Dr Richard Rathbun for the obligations superintending making of blocks from these drawthe and also for reading proof sheets while this work was ings, going through the press Dr Wm Owen, of the University of Chicago, and Prof H N Hoffman, of Indiana University, also rendered me and valuable service in correcting the misspelled names of Rafinesque Dr Frederick Starr, of the University of Chicago, has others also kindly revised the proof sheets of this paper with regard to the I also desire to acknowledge the spelling of geographical names many courtesies I received from Hon Powell Clayton, U S Minister In to Mexico, while doing field work in Mexico in 1901 and 1903 I wish to assume for these responsibility acknowledgments making whatever errors list this volume may contain In the present paper it has been my purpose to give a descriptive of the fresh -water fishes of Mexico, and keys to assist in identifying It is impossible to draw an arbitrary line separating the fresh-water fishes from those of the salt water A few of the species of Pomadasys, Achirus, Gobius, and the like, included in this work, the same are properly salt-water fishes in fresh water I have listed them here rather as fishes found I have examined every have had reference and access that throws light on In the preparation of this publication paper to which I PREFACE vii the subject in question, and I have drawn from these material suited In the sequence of the orders and families I have folto my purpose The lowed Jordan and Evermann in Bull 47, U S Nat Mus sequence of genera and species has been changed whenever, in the I have also of new information, it appeared necessary made free use of the publication above mentioned for material A special effort has in the characterization of orders and families been made to bring together, in as useful a form as possible, our present knowledge of the fresh-water fishes of Mexico north of the Isthmus The study of this group of animals in this region of Tehuantepec is of especial interest, for between these two lines is the meeting place In this respect these bounof the northern and the tropical faunas in a measure natural ones, because very few species of dary lines are the northern line, and but few northern repretropical fishes reach found south are farther than the Isthmus of Tehuantepec sentatives In addition the subject presents very interesting material for a study light in geographical distribution ERRATA Gaham Page v, line 33, Page xviii, line g, Page Page xix, line 6, Page xxxi, line 49, Page
