OOO.-A CATALOGUE OF THE FISHES KNOWN TO INHABIT THE 

 WATERS OF NORTH AMERICA, NORTH OF THE TROPIC OF 

 CANCER, WITH NOTES ON THE SPECIES DISCOVERED IN 1883 

 AND 1884. 



By David Starh Jordan, 



The Synopsis of the Fishes of North America, by David S. Jordan 

 and Charles H. Gilbert (Bulletin United S *-e8 National Museum No. 

 16), was finished in September, 1882, and v^as issued to the public 

 about April 1, 1883. 



Since the publication of that work an active study of North Ameri- 

 can fishes has brought to light many species not included in the Synop- 

 sis, and has shown various errors in the nomenclature of species already 

 known. The additions are chiefly in the Bassalian or deep-sea fauna 

 of the Atlantic, in the tropical fauna of the Florida Keys, and in the 

 fresh- water fauna of the lower part of the Mississippi Valley. 



It was at first determined to issue these addenda in the form of an- 

 nual supplements to the Synopsis, but the publication of the supplement 

 for 1883 having been delayed till January, 1885, it has been thought 

 best to unite the lists for 1883 and 1884, and to put the matter in the 

 present form. 



I have, therefore, given a list representing the present state of our 

 knowledge of the fishes found north of the Tropic of Cancer, iu American 

 waters. In all cases where a species is included which is not iu the 

 Synopsis, or in which a name is used in the latter work, difierent from 

 that here adopted, I have given an explanation, reference or description 

 in the form of a foot-note. Species already fully described elsewhere in 

 publications of the U. S. National Museum are not redescribed here. 



In matters of nomenclature and classification I have followed, in this 

 list, the arrangement in the Synopsis, unless important reasons for de- 

 viation have appeared. In such cases I have endeavored to avoid pre- 

 mature changes, and the substitution of one doubtful opinion for another. 



In this list the families, genera, and species are numbered consecu- 

 tively from the first. These numbers necessarily difter from those in 

 the Synopsis. The numbers used in that work are here placed in 

 parentheses after the names.
