NOTROPIS. 159 
Anal 9-10. Ventrals inserted a little before the origin of dorsal, which is equidistant from the tip of 
snout and base of caudal or a little nearer the latter. 34 to 38 scales in a longitudinal series, 6 to 8 in 
a transverse series from origin of dorsal to lateral line, 3 or 4 between lateral line and root of ventral. 
Lateral line usually complete. Caudal peduncle 13 to 2 as long as deep. A dark vertical bar behind 
the head ; a lateral stripe on the posterior part of the body. 
Hab. South Dakota to Northern Mexico: 
In Mexico recorded from the Rio Santa Maria, Rio Carmen > (Meek), Rio 
Sauz° (Meek), and Rio Conchos** (Meek) in Chihuahua; Rio San Juan in

Very similar to WV. luérensis, but with the head smaller (4 to 44 in the length of the fish) and the anal fin 
usually longer (of 10 to 12 rays).

Meek, Publ. Columbian Mus., Zool. v. 1904, p. 74, fig. 21°. 
Very close to NV. lutrensis and perhaps not really distinct, but the lateral line incomplete, terminating below 
the origin of the dorsal fin, and only 2 scales between the lateral line and the base of the ventral fin.

11. Notropis calientis.

Depth of body 34 to 32 in the length of the fish, length of head 32 to 4. Diameter of eye 4 in the length of 
head. Mouth terminal, oblique ; jaws equal anteriorly ; snout obtuse. Dorsal 9, with 7 branched rays. 
Anal 7-8, with 5 or 6 branched rays. Ventrals inserted below or a little in advance of the origin of 
dorsal, which is nearly equidistant from tip of snout and base of caudal. 32 to 35 scales in a 
longitudinal series, 6 or 7 in a transverse series from origin of dorsal to lateral line, 3 or + between 
Lateral line incomplete, not extending further back than the 
lateral line and base of ventral fin. 
Caudal peduncle twice as long as deep. A dark lateral stripe. 
vertical from the origin of the dorsal fin.
