A COLLECTION OF FISHES FROM THE ISTHMUS OF 



TEHUANTEPEC. 



BY SETH EUGENE MEEK. 



The small collection of fishes on which this paper is based was 

 made by E. Heller and C. M. Barber for the Field Columbian 

 Museum in December, 1904, and January, 1905, at Achotal, in 

 the State of Vera Cruz, and San Geronimo and Niltepec in the 

 State of Oaxaca. Most interesting are the cichlids, of which 

 there are besides one new species several specimens of Cichlasoma 

 mojaira Meek and CifMasoma evermanni Meek. The former 

 species was previously known only from one small specimen 

 from San Geronimo. The collection also records the northern 

 known limit of Cichlaaoma trimaculatum Giinther.
