‘of pupil. Scales rather large, smaller along and on bases of rayed 
vertical fins. Scales in 6 rows on cheek. Lateral line complete. 
Spinous dorsal inserted opposite origin of pectoral, margin 
notched, and spines graduated from fourth, fifth and sixth, which 
are subequally longest. Rayed anal inserted about midway be- 
tween middle of orbit and base of caudal, high, and when de- 
pressed reaching beyond base of caudal. Spinous anal inserted 
about midway between posterior margin of orbit and base of 
caudal, graduated to third spine which is longest. Rayed anal 
high, and reaching back well beyond base of caudal. Caudal 
rounded. Pectoral reaching margin of rayed anal. Ventral in- 
serted just behind origin of pectoral, reaching origin of rayed 
anal, and spine reaching base of third anal spine. Color dull 
olive, with indistinct traces of vertical dark bars. Ear flap small, 
black margined with blue and a pearly spot in front. A dark bar 
about as wide as pupil down below eye. Body everywhere with 
round bright azure spots in irregular series, most distinct on

Creek, near Trenton. 
I have examined a large series of examples taken in the Dela- 
ware basin at Trenton and Brown Mills. It is a beautiful little 
fish, preferring rather still clear waters, or only those with a 
gentle current. I have found them mostly among the weeds or 
grasses along borders of ponds, where they are at times abundant.
