16. Notropis zoiiatus (Agassiz). 
Head 4 iu the length of the body, depth to 5^-. Sides with a dark plumbeous 
baud, above which is usually a more narrow silver band; upper part of body dusky; 
a dark vertebral line; a dark band on shoulder from upper edge of opercle to base of 
pectoral flu. Lower part of body and the lower fins on males with some red. The 
position of the dorsal fin is variable ; in some specimens it is midway between tip of 
snout and base of caudal fin ; in others the middle of the fin is midway between 
base of caudal fin and tip of snout. It is usually further forward on the larger and 
deeper specimens. 
This species is very abundant in southern Missouri. It prefers cool, clear water, 
and is usually taken with W. megalops. Its colors are brighter when taken from 
streams with clear, cool water. It is one of the largest, handsomest, and most grace- 
ful of the species of Notropis. Meramec Eiver and Spring Outlet, abundant. 
17. Notropis umbratilis cyanocephalus (Copeland). 
First dorsal ray midway between the eye and caudal fin. Body deep, compressed. 
Color pale greenish in life, with more or less pinkish on the sides. All specimens 
taken were less than inches in length. A dark vertebral line and a dark spot at 
base of dorsal in front. Big and Little Dry Forks, abundant. 
According to the studies of Dr. Gilbert, Notropis ardens, cyanocephalus, atripes, 
lythrurus, matutinus, and nigripinnis are indistinguishable as species from N. umbratilis. 
18. Notropis rubrifrons (Cope). 
Head 4J to 4^ in the length of the body; depth 5 to 5^; scales 40 to 42 in the 
lateral line. Eye small, scarcely equal to length of snout, its diameter 3| in length of 
head in specimens 2^ inches in length. A broad, high plumbeous baud on sides 
overlaid with silvery; lateral line decurved, usually forming lower boundary of the 
plumbeous band. Some red on the lower parts of the body on some specimens. Anal 
rays 9 or 10, usually 10. Meramec River and Little Dry Fork, common ; Big Dry 
Fork, scarce. 
19. Notropis lutrensis (Baird and Girard). 
Big Dry Fork. 
20. Hybopsis amblops (Rafinesque). 
Big Dry Fork, scarce. 
21. Hybopsis kentuckiensis (Rafinesque). 
Meramec River, Big and Little Dry Forks, common. 
22. Semotilus atromaculatus (Mitchill). 
Meramec Spring and Little Dry Fork, not common ; Big Dry Fork, scarce. 
23. Notemigonus chrysoleucus (Mitchill). 
Little Dry Fork, one specimen. 
24. [Salmo irideus Gibbons. 
This species is not native to the Ozark region. It has been introduced into the 
streams in Missouri by the Missouri State fish commission. Several specimens were 
taken by us in the Meramec Spring Outlet.] 
25. Fundulus catenatus (Storer). 
Usually with few crimson spots on opercles and sides of the body. The lateral 
stripes are much broken in some specimens. A few faint dark vertebral bars are 
quite conspicuous on the posterior portion of the body. The dorsal fin is larger in 
adult males than in females. Meramec Kiver, common ; Big Dry, scarce.
