THE AMERICAN CHARACIDAE. 



The specimens from the Parahyba Basin differ from typical A . fasdatus in 

 so many and so striking respects that they may also be distinguished by a varietal 

 name. 



Head 4.25-4.4; depth 2.5-2.66; D. 11; A. usually 31 or 32, (27-34) ; lateral 

 hne usually 39 or 40 (37-41); eye equals Lnterorbital, less than 3 in the head; 

 one maxillary tooth; 4 or 5 teeth in the outer tow of the premaxillary in the 

 ratio of 2:1. 



Gill-rakers 9 + 16. 



Roivs of scales heloio the lateral line deflected towards the anal by interpolated 

 rows of scales, the first of the interpolated rows beginning at a point above the 

 middle of the ventrals and one or two rows of scales below the lateral line. 



Tips of dorsal, caudal rays, and anal usually dark; tips of ventrals, more 

 rarely dark; the tips of the pectorals also dusky; middle caudal rays dark ; tips 

 of first two rays of the anal milk-white.
