The material described and recorded by Jordan, Woolman, 

 Jordan and Snyder, and by Meek, lias been re-examined. The 

 specimens recorded by Woolman from Salamanca as Chara- 

 codon variatus represent the females of both that species and 

 of Goodea atripinnis. Having identified specimens of the 

 present species with Characodon variatus, it is not surprising 

 that he was unable to satisfy himself of the identity of Chara- 

 codon variatus (male) with C. ferrugineus (female, of 

 variatus ) . 



Goodea atripinnis is essentially a stream species. It is not 

 represented in the collections from lakes Chapala, Patzcuaro 

 and Zirahuen which have been examined. All of the speci- 

 mens from these three lakes represent the larger, finer scaled 

 species, Goodea hiitpoldi. It is highly probable that all 

 records of this species from Lake Patzcuaro refer to luitpoldi. 



The only lake specimens of atripinnis seen are from the 

 small Lake Cuitzeo.'' In addition to their lighter color, they 

 have the dorsal fin farther forward than usual. The distance 

 from the origin of the dorsal to the end of the caudal when 

 measured forward extends nearly to the eye, instead of little 

 bej'ond the opercular margin, as usual in the several series of 



3 In recording these specimens Meek (1900) mentioned that "the 

 specimens from Lake Cuitzeo are very light in color, a feature character- 

 istic of all the fishes taken from this and Patzcuaro Lake. ' ' Regan 

 (1908) erroneously construed this sentence to mean that specimens of 

 atripinnis were being recorded from Patzcuaro.
