122 BULLETIN OF THE UNITED STATES FISH COMMISSION. 
There is considerable variation in the width of the head and in the length of the 
pectoral spines (If to2J in head). A 16. Pectoral spine retrorse- serrate on the outer 
margin, the inner margin with coarse teeth near the base. 
2 Noturus gilbert! Jordan & Evermaun. 
About two-fifths of the specimens of ‘‘ Mad Tom” obtained at Eoanoke and Salem 
belong to this species, well distinguished by its color, and by the form of its adipose 
fin, caudal fin, and pectoral spines. 
3. Moxostoma papillosum (Cope). 
A few young specimens taken at Eoanoke. 
4. Moxostoma cervinum (Cope). 
Common at the foot of mill-dams and in swift waters. 
5. Catostomus nigricans (Le Sueur). “ Dutcbnian.” 
Common; specimens dark in color. Lat. 1. 47. 
6. Catostomus teres (Mitchill). 
Common. 
7. Campostoma anomalum (Raflnesque). 
Not rare. Lat. 1. 49 to 52. 
8. Exoglossum maxillingua (Le Sueur). “Nigger Fish.” 
Very common ; a sluggish fish living near the bottom. Lat. 1. 57. 
9. Chrosomus oreas (Cope). 
Very abundant iu the clear brooks; rare in the river; the most ornate of all our 
CyprinidcB. In life head, belly, and lower jiarts deep scarlet; fins bright yellow, with 
scarlet at base ; back with black vertical bars ; a black band from snout through eye 
to the anal fin, very broad and very distinct in males ; another band beginning above 
this one, separate from it at a point before the vent, and going straight to caudal. 
These markings are quite distinct from the two nearly parallel black bands seen in G. 
erythrogaster. G. oreas also differs in having a slightly longer snout, longer preorbital, 
and longer maxillary, which extends nearly to the eye. It should probably be ranked 
as a distinct species. 
10. Notropls procne (Cope). 
Not rare; a few specimens are extremely jjale, having no black on scales on sides 
of head. These, however, have the same form as the others and show traces at least 
of the spots at base of caudal. 
11. Notropis megalops (Eafinesque). 
Common. Of this species two distinct forms or varieties, possibly distinct species, 
are found, neither of them quite like any form of N. megalops which I have met in any 
other stream. The two forms are very different from each other and may be distin- 
guished even when very young. The one called 'v?hV.' cerasinus by Professor Cope 
abounds in the small streams, the other which I call var. albeolus is found in the 
river. 
Notropis megalops cerasinus is small in size, seldom exceeding 4 inches. In life it 
is steel-blue above, the body flushed with pink and the fins all bright red. The sides 
are always marked by irregular blackish cross-blotches and bars, formed by a broad.
