faces ; from Cliola by the backward dorsal ; from Cyprinella by the unser- 

 rated teeth. It however is probably rather a section of Nototropis, than a 

 distinct genus. 



25. PHOTOGENIS STIGMATURUS. Sp. nov. 



Body elongated, fusiform, compressed, more slender and graceful than 

 callistius ; depth 4f in length (4£ to 5). Head quite long, truncate at the 

 snout, 4| in leugth, (without caudal) (4t to 4£), rounded above, and in males 

 thickly tuberculate. Mouth large for the genus, somewhat oblique, over- 

 lapped by the narrow upper jaw. Eye not large, about 4i (4J to 5) in 

 head ; iris white ; maxillary reaching beyond nostrils. Scales large, deep, 

 closely imbricated, 45 in the course of the lateral line, 19 or 20 in front of 

 the dorsal. 



Fins moderate ; dorsal behind ventrals, slightly nearer the caudal than 

 the snout, its height about 6i times in length of body ; pectorals not 

 nearly reaching ventrals, the latter to vent. 



Color pale clear olive, with a rich, faint blue lustre, much paler than in 

 either of the other species here described. Sides and fins in males with 

 the usual satiny pigment ; cheeks somewhat pinkish, but no red pigment. 

 Black dorsal spot not very distinct, but visible in all adults. A very dis- 

 tinct, large, oblong or quadrate, jet black spot at the base of the caudal, 

 extending up on the rays. This spot is very conspicuous in all specimens — 

 even the smallest. Its length is usually about one-third that of the head. 

 In no other species known to me is this spot so large or distinct. 



Teeth 1, 4-4, 1 ; dorsal rays I, 8 ; A., I, 8 ; length 4 inches. 



Habitat. Small tributaries of the Etowah, Coosa, and 

 Oostanaula, where it is the most abundant minnow. It is 

 everywhere known as Spotted Tail Minnow, or Spot Tail. 



This is the least gaudy, though perhaps the most graceful, 

 of all our species of this* genus. It reaches a larger size 

 than any of the others. 



26. PHOTOGENIS CALLISTIUS. Sp. nov. 



Body rather stout and compressed, much as in pyrrhomelas, much heav- 

 ier forward, and more comutus -like, than in stigmaturus or cairuleus. Dor- 

 sal outline considerably elevated. Depth 4J (4i to 5) in length. Head 

 stout and rather blunt, 41- in length. Upper part of head flattish, in males 

 sparsely covered with smallish tubercles, which are always arranged in 

 a few more or less distinct longitudinal rows, not scattered without order, 

 as in other species. , 



Mouth rather large, slightly overlapped by the heavy snout, nearly hor- 

 izontal, the maxillary reaching to the nostrils. Eye rather large for the 

 genus, 3| in head (3^- to 4).
