FISHES OF THE MEXICAN PORTION OF THE RIO GRANDE BASIN. 
Tlie number of species which have been reported from the Mexican portion of the 
Rio Grande basin is 54. Of this number, 16 species (indicated in the following list by 
an *) have not as yet been collected from any United States locality. The remain- 
ing 38 species have been found either in the Rio Grande or on the Texan side of that 
stream. Those species which are regarded as belonging properly to the Mexican 
fauna, but which have extended their range into Texas (9 in number), are indicated 
by the f. Those species which belong to the fauna of the southwestern United States, 
but which have spread more or less into Mexico (29 in number), are indicated by the 
In Dr. Eigenmann’s recent list of the fresh-water fishes of Central America and 
southern Mexico,* only 5 species are named which are also found in the Rio Grande 
basin. These five are Gambusia gracilis (= affinis), Pcecilia couchii ( couchiana ), Tetra- 
gonopterus argentatus , Gobiomorus dormitator , and Dormitator maculatus. No Mex- 
ican locality is given for Tetragonopterus argentatus. We have not been able to find 
any Mexican reference nor the basis for the statement “Arkansas to Mexico” given 
in Jordan and Gilbert’s Synopsis and repeated in this paper by Dr. Eigenmann.
