Assistant Curator, Division of Fishes. 



During the years 1892 and 1894, while exploring for the TJ. S. Depart- 

 ment of Agriculture, Messrs. E. W. Nelson and E. A. Goldman collected 

 eighteen species of fishes in various parts of Mexico. One of the species 

 is here described as new; the others are interesting on account of local- 

 ities, as are Mr. Nelson's observations on AnablepH from Tehuantepec. 



Tlie collection here recorded was transmitted to the Museum April 20, 

 1897, forming accession 31947. In 1897 the same collectors procured 

 several additional species of fishes in Mexico, including Agonostomus 

 nasutus, Chirostoma humboldtianum, Heros beani, and Gobius banana.
