THE FISHES OF NEW JERSEY. i6i 



broad and slightly convex. Opercle smooth. Gill-rakers 9+14, 

 slender, longest equals pupil. Scales of rather uniform size, and 

 not much crowded on predorsal region. Dorsal inserted a little 

 before tip of pectoral or much nearer tip of snout than base of 

 caudal. Anal inserted about midway between base of sixth 

 branched dorsal ray and base of caudal, and reaching beyond 

 latter. Caudal a little emarginate, lobes rounded. Pectoral ex- 

 tending four-fifths of space to ventral. Ventral inserted about 

 opposite base of fourth branched dorsal ray, and extending four- 

 fifths of space to anal. Dark olive on back, paler below, and 

 dusky shades above. Fins with dusky. Length 7 inches. Batsto 

 River. 



The adult is olivaceous above in life, sides paler, and lower 

 surface becoming white. Body, especially sides, with brassy re- 

 flections. A pale band, most distinct when fish is in the water, 

 extends from upper end of gill-opening to base of upper caudal 

 lobe. This indistinctly defines black lateral band of young which 

 has almost completely faded. A median pale streak extends from 

 tip of snout tO' base of caudal, also distinct when fish is in water. 

 Side of head with brassy reflections, and its lower surface opaque- 

 white like lower surface of abdomen. Iris of three circles of 

 color, one next tO' pupil pink, next pale gray, and outer one white. 

 Dorsal and caudal dark or dusky, membranes deeper than rays, 

 which are somewhat dilute ruddy. Anal dusky, rays becoming 

 translucent brownish-white basally, former with upper margin 

 same, and lower or inner rays of both fins ruddy, becoming deep 

 or wine-color somewhat in middle of fins. Inside of gill-opening 

 pearl-colored. This example from tributary of Crosswicks Creek, 

 near Trenton, taken in May, 1904. 



A young example 2^ inches long, in the vittatus stage, was 

 taken in the same locality. When living the ground color of back 

 was pale brownish-olivaceous and edge of each scale distinctly 

 darker. Along middle of side a dusky or black band, less than 

 pupil, extending from tip of snout to base of caudal, where it is 

 intensified in some examples. Lower surface, or below band, 

 opaque-white with a silvery sheen. Lips white. Above black 

 lateral band a paler shade than ground-color of back, and edges
