Three adult specimens, two with deeper, one with shallower 

 body. First, scales 4^-35-4; head 3.5 times, depth three times in 

 length. Second, scales 5-37-5; head 3.75, depth three times in 

 length. Third, scales 5-38-5 ; head 3.75, depth 3.6 times in 

 length. All with anal ra^^s 10, and a minute anterior spine. Ten 

 dark dorsal cross-bands besides the three lateral spots ; the ap- 

 propriate bands descending between the spots. The young are 

 very strongly and handsomely cross-banded. 



CHARACIDIUM ETHEOSTOMA, Cope, sp. nov. 



The discovery of this little fish is interesting as extending the 

 range of this genus over the whole of Brazil, it having been known 

 heretofore from the neighborhood of Lagoa Santa, from a tribu- 

 tary of the coast river, the Rio das Yelhas. Prof. Reinhardt, 

 who discovered it, called the species from that locality Gh. fas- 

 cmtum} The nares are separated, the anal fin short, the teeth 

 are simple, acute, and fixed in a single series in each jaw ; none 

 on the maxillary. Lateral line complete. 



The species here described has much the coloration of the 

 Poecilichthys or Etheostoma of our North American streams. 



Depth into length 5.25 times; head 5.75 times in same. Bran- 

 chiostegal membranes fissured farforwards. Dorsal fin commencing 

 in front of ventrals R. 11 ; A. 8 ; V. 9 ; P. 11, reaching ventrals, 

 ventrals reaching anal, caudal deeply forked. Scales 1. 1. 33, 1. tr 

 8 ; striate. Orbit equal muzzle 3.6 times in head, equal inter- 

 orbital width, and length of muzzle ; profile nearly straight, lips 

 about equal ; maxillary bone to orbit. 



In spirits yellowish, probably hyaline in life, with a black lateral 

 band from end of muzzle, and nine quadrate brown dorsal spots 

 from nape to tail. There is more or less connection between the 

 spots and band, and shades across the under side opposite to 

 these. Fins unicolor, light. Sides of head silver, end of chin,
