Description.—Body heavy, deep and thick, stouter and thicker than in the southern 
Chenobryttus gulosus; depth 24 in length; head about 22; mouth large, its maxillary 
reaching nearly to posterior margin of eye—the supernumerary bone strong; scales on 
the cheeks in 7 to 9 rows, rather smaller than in gulosus ; mucous pores about head very — 
large ; opercular flap rather large and broad but not long; dorsal inserted anteriorly, 
the first spine being over the ear-flap; spines very stout, the longest as long as from 
snout to middle of eye; color in spirits very dark, almost black; three oblique bands 
across the cheeks and a black opercular spot, pale-margined below, as large as the eye; 
young specimens are profusely mottled, as are the young of Ambloplites, and further- 
marked with vertical chains of spots; in life, adults dark olive-green above, sides green- 
ish and brassy, with blotches of pale blue and bright coppery red, the red predomina- 
ting ; belly bright brassy yellow, profusely mottled with bright red; lower jaw chiefly 
yellow ; iris bright red; opercular spot as large as eye, black, bordered below with cop-: 
per color; 3 or 4 wide dark red bands radiating backward from across cheeks and oper- 
cles ; separated by narrow pale blue interspaces; upper fins barred with black, orange, 
and blue, the former color predominating ; lower fins dusky ; a small black spot on last 
rays of dorsal, with a few dusky specks around it. This species is best distinguished 
from Ch. gulosus, by the position of the dorsal, the first spine being situated over the 
opercular lobe, while in C. gulosus the first spine is situated directly over the posterior 
portion of the base of the pectorals. Length 8 to 12 inches. 
Habitat, Lake Michigan. Mississippi Valley, chiefly northwestward. Michigan 
(Cope), Lake Michigan (Jordan), Illinois River (Forbes, Nelson), Wabash River (Jordan). 
This species has not yet been recorded from Ohio, but it doubtless occurs in the west- 
ern part of the State and in the Ohio River. 
It is a stout, voracious species, strongly resembling the Rock Bass. It is ‘‘ gamey,”’ 
and is, where abundant as in the Upper Mississippi, valued as a pan-fish. All the speci- 
mens examined from the Gulf States, belong to the allied species or variety C. gulosus. 
Diagnosis.—This is the only one of our Ohio fishes which has teeth on 
fin.

Type, Lepomis ictheloides, Raf. = Bodianus rupestris, Raf. 
Etymology, amblus, blunt; oplites, armed. 
Dorsal fin much more developed than anal fin, the soft parts of the two fins about 
equal and terminating at the same vertical behind ; dorsal fin with 11 or 12 (10 to 13) 
spines; anal normally with 6 (5 to 7); caudal fin emarginate ; scales ctenoid; mouth 
large, teeth on vomer, palatine and pterygoid bones; a single large patch of teeth on 
/ 
the tongue, three spines in the anal fin, and ten in the single dorsal
