Family V. Cyprinid^e. 73 



peduncle 2I in head; lateral line above pectoral considerably de- 

 curved. 



Color olivaceous; a silvery band from eye to base of caudal, with 

 a narrow light line above it. Length about 2.25 inches. 



The males of this species are much the darker, with the lateral 

 band very faint; tubercles on head and nape. Females with well- 

 developed eggs. This species resembles Nototropis lutrensis, but is 

 more slender than that species, and the lateral band is more promi- 

 nent on anterior half of the body; the mouth is also larger. 



65. Nototropis garmani (Jordan). 



Cyprinella ritbripinua Garman, Mus. Comp. Zool., 1881, qi; Lago 

 del Muerte, near Parras, Coahuila. 



Notropis garmani Jordan, Cat. Fishes N. Amer., 1885, 813; name 

 a substitute for mbripinna, preoccupied: Jordan & Ever- 

 mann, Bull. 47, U. S. Nat. Mus., 1896, 281. 



Basin of the Rio Nazas. (Lerdo; Santiago Papasquiaro.) 



Head 3^ to 4; depth 2^ to 4; D. 9; A. 10 to 12; scales 7-36-3. 

 Body elongate to very deep, much compressed, the back somewhat 

 arched; head rather small; snout bluntish, 4 in head; mouth small, 

 oblique, terminal, the lower jaw included when mouth is closed; the 

 tip of maxillary reaching vertical from anterior margin of the orbit; 

 teeth 4-4, narrow grinding surface, tips hooked; eye 3^ in the head; 

 origin of dorsal fin midway between base of caudal and pupil; about 

 18 scales between nape and dorsal fin; base of dorsal 1% in head, 

 slightly less than length of longest ray; fins all large, the tips of the 

 pectorals, in the deeper specimens, reaching base of ventrals; pectorals 

 ii in head; ventrals 1% in head; base of anal equals length of 

 longest anal ray, ij4 in head; scales rather large, deeper than long, 

 especially on deepest specimens ; caudal fin forked ; caudal peduncle 

 very slender, its least depth 2*^ in head; vertebrae 16 + 17 = ^^. 



Color bluish above, lighter below; a dark band on middle of the 

 body on posterior half; no caudal spot; fins plain; males in breeding 

 season with much red on body and fins, and tubercles on body; old 

 males with tubercles over the entire body. Length about 3 inches. 



This species is very variable in form and color; it differs chiefly 

 from Nototropis lutrensis, which it most resembles, in having larger 

 fins and a much more slender caudal peduncle. The specimens from 

 Lerdo are very- much compressed, appearing much like half-starved 

 fish; dark olivaceous, not much silvery. The large males are very 

 red in life, with a dark bar followed by a lighter one just back 

 of head. 



This species may possibly prove to be a variety of Nototropis 

 lutrensis. Spawning time the latter part of May and in June.
