head large; snout projecting, shorter than eye ; mouth large; maxillary reach- 
ing to posterior border of eye; opercular spot small, black, confined; eye large, 
3£ to 4 in head; scales large, 6 to 8 rows on cheeks; dorsal spines moderately 
elevated, longest reaching to posterior border of pupil ; ventrals and pectorals 
not reaching anal, ventral spine 1£; olive greeu, tinged with brassy ; a dark 
spot on each scale, these forming interrupted long stripes; a dark spot below eye; 
vertical fins reticulated ; head, 2.J- to 2f; depth, 2 to 2£ ; D. xi, 10; A. vi, 10; lat. 
1., 38 to 42 ; L., 12 inches Rupestris, 5. 
aa. Scales ou cheeks rudimentary iu the adult (stripes more interrupted and fius less 
reticulated), otherwise as in rupestris Cavifrons, 5&.

Centrarchus peutacanthus Cuv. & Val., Hist. Nat. Poiss., in, 88, 1829 (Wabash R.). 
Habitat: Lake Champlain to Manitoba, south to Louisiana in rivers 
and lakes west of the Alleghany Mountains. 
Etymology : Latin ; living among rocks. 
5b. AMBLOPLITES RUPESTRIS CAVIFRONS. 
Ambloplites cavifrons Cope, Journ. Acad. Nat. Sci. Phila. 1868, 217 (Roauoke R.). 
Habitat : Roanoke River. 
Etymology : Gavus , hollow ; frons , forehead. 
An examination of an adult of this form from Roanoke River shows 
that cavifrons should probably be maintained as a distinct subspecies. 
There is nothiug peculiar or different, in any respect from rupestris about 
the physiognomy of cavifrons , the sole tangible difference being in the 
scaling of the head.
