844 FISHES—CYPRINIDZ. 
Diagnosis —This species much resembles H. stramineus, but differs in 
proportionately greater length of the pectorals. Itis found in the streams 
of southern Michigan and Wisconsin, and doubtless in northern Ohio 
also, though I have not seen it. Nothing is known of its habits. 
64 Hupsonius stRAMINEUS (Cope) Jordan. 
Straw-colored Minnow. 
Hybognathus stramineus, Copr, Proc. Acad. Nat. Sci. Phila , 1864, 283. 
Hybopsis stramineus, Cork, Trans, Am. Philos. Soc., 1826, 331—JoRDAN, Man. Vert., 2d 
Ed., 1878, 291. 
Description.—Body moderately stout, little compressed; head rather broad, with 
rounded angles; mouth small, inferior, horizontal; snout very obtuse; eye large, 3 in 
head ; fifteen rows of scales in front of the dorsal fin; pale olivaceous; sides little sil- 
very; usually a darker dorsal band ; fins all plain; head 4; depth 5; scales 5-36-4 ; teeth 
4-4, Length, 24 inches. 
Habitat, Ohio Valle, and Lake region, abundant in small streams. 
Diagnosis.—This insignificant fish may be known by its large scales, 
and, in general, by the absence of all peculiarities. 
Habits—This fish, the feeblest in structure of all our minnows, and one 
of the smaliest and dullest colored, occurs in considerable abundance 
throughout the State, mostly inhabiting the small streams. It is found 
in company with Hyborhynchus notatus, which it considerably resembles. 
The individuals of the latter are much more abundant. 
A related species which is found in Kentucky and Virginia, and may occur in Ohio, is 
Hudsonius microstomus (Raf.) Jor. (Minnilus microstomus Raf., Hybopsis longiceps Cope), 
characterized as follows: 
Body elongate, the caudal peduncle not contracted ; mouth inferior, horizontal, small, 
the maxillary not reaching the line of the eye; fins rather short; eye large, three and a 
half in head; fourteen scales before the dorsal; preorbital bone much longer than 
deep; olivaceous, translucent, a silvery lateral band, along which is a black speck at 
the origin of each tube of the lateral line; D.8; A.7; scales 5-33-2; teeth 4-4, Length, 24 
inches. ‘
