108 FISHES OF PENNSYLVANIA. 

form, very dark greenish olive, with darker margins, except the pectorals, 
which are light olivaceous, and the ventrals, the spinous rays of which 
are uncolored. SSome specimens may be better described as dark golden 
green, with longitudinal bands of -dark olive, broken up by cloudings 
of greenish.” 
Genus ENNEACANTHUS Gi. 
120. Enneacanthus obesus (Barrp). 
The Banded Sunfish. 
The body of the banded sunfish is elliptical in form, its depth more than one-half 
total length without caudal; its thickness equals two-fifths of its depth. The 
caudal peduncle is short and stout, its least depth one-third greatest depth of 
body; the head is short, two-fifths of total length without the caudal; the snoutis very 
short and oblique, its length about two-thirds of the diameter of the eye, which is 
one-third as long as the head and exceeds the width of the interorbital space; the 
mouth is oblique, moderate in size, the maxilla broadly expanded posteriorly and 
reaching to below the middle of the eye; a supplemental maxillary bone; a black 
opercular flap two-thirds as long as the eye; scales on cheeks in four rows; gill- 
rakers short and spiny, thirteen developed on the first arch, the longest scarcely one- 
half as long as the eye. The first dorsal spine is over the pectoral base, minute, less 
than one-half as long as the second, which is two-thirds as long as the eye; the spines 
increase in size to the last, which is one-half as long as the head; the fourth and 
longest soft ray is two-thirds as long as the head; the ventral begins a little behind 
the pectoral base; the spine is two-fifths as long as the head; the fin reaches to the 
second anal ray, its longest ray produced into a filament; the anal begins under the 
thirteenth scale of the lateral line; the base is two-thirds as long as the head; the 
first spine is two-thirds as long as the second, which is as long as the eye; the last 
spine is as long as the eye and snout combined; the anal rays increase in length to 
the fifth, which’is as long as the head without the snout; the pectoral is below the 
median line and reaches to above the third anal spine; the caudal is rounded, the 
middle rays as long as the head without the snout; the lateral line is imperfect after 
the seventeenth to the nineteenth scale. D. IX,11; A. T1I, 10; V. 1,5; P.12. Scales 
5-32-10. The type of the species, No. 6538, United States National Museum, 
from Beesley’s Point, N. J., is here described; it is three anc three-fourths inches 
long. 
The banded sunfish inhabits coastwise streams from Massachusetts to 
Florida. It occurs in southeastern Pennsylvania but is rare. 
This species grows to a length of three inches. It is olive green in 
color, with five to eight dark cross bars intermingled with golden or 
purplish spots. There are lines and spots alsoon the cheeks. The flap 
on the opercle contains a velvety black spot with a purple border. Be- 
low the eye there is a dark bar. Thisis a beautiful littie species but has 
no economic importance. 
121. Enneacanthus simulans (Cope). 
The Blue-spotted Sunfish. 
The blue-spotted sunfish has an elliptical body, its greatest depth one-half of its 
total length without the caudal, and its thickness nearly two-fifths of its depth. The 
caudal peduncle is short, its least depth one-third of the greatest depth of body; the 
head is moderate in size, three-eighths of the total length without the caudal; the
