The identity of Xenenduni with Goodea has already been 

 indicated by Meek. 



It may be of some historic interest to mention here that 

 the viviparity of Goodea -vvas noted as early as 1896, by Dr. 

 Herrera.^

Specimens from Lake Chapala ("Xenendum xaUscone") 

 have a band of fine teeth behind the main row, as in topotypes 

 of luitpoldi from Lago de Patzcuaro, and agree also in other 

 respects. 



Goodea luitpoldi is a species of the larger lakes. It is not 

 known from the smaller streams, which are inhabited by 

 Goodea atripinnis. Specimens of the latter form from Lake 

 Cuitzeo, in fact, show an approach, in some respects, toward 

 luitpoldi. 



The present species is a larger fish than atripinnis, and 

 usualh' differs from it in the more anterior position of the 

 dorsal fin, and constantly in the smaller size of the scales. 



The young of luitpoldi are blotched like those of atripinnis. 

 The blotches soon become obsolete, however, the color pattern 

 of the adult of both sexes consisting of longitudinal streaks 

 between the scale rows.
