Eigenmann based this species on a male, as the type, with which 

 were associated seven females, which seem to belong to a distinct 

 species, subsequently described by Regan as P. picta. The apparent

differences between the single male and the females were supposed to 

 be those of sexual dimorphism. Regan's material contained males 

 agreeing in coloration with these females, to which they unquestion- 

 ably belong, showing their specific distinctness from P. melanzona. 

 Regan's supposition that the type of A. melanzoniis is a male of Lebistes 

 reticulatus is erroneous, as will be seen by reference to the accompany- 

 ing figure of the anal fin, which is that of a PcBcilia. 



The type, which is unique, has a broad lateral band of clear white 

 or silvery, bordered by narrow lines of chocolate. Females of this 

 species are unknown.

As stated in the remarks under Pcecilia melanzona, that species was 

 a composite based upon a male (type) and several females supposed 

 to belong to it, but shown by males in Regan's material to be distinct 

 and described by him as the present species. Both are distinct and 

 valid species of the genus Pcecilia. Males and females of this species 

 are more or less similar in coloration.
