of vertical fins, those on caudal very fine and crowded. Cheek., 

 opercle and upper branchiostegals scaly, rest of head naked. 

 Lateral line rather obscure, complete, of simple tubes. Dorsal 

 inserted a little nearer origin of ventral than base of caudal, 

 median rays highest. Anal inserted a trifle before origin of 

 dorsal and similar. Caudal emarginate. Pectoral a trifle more 

 than half way to ventral. Ventral inserted a little nearer origin, 

 of anal than that of pectoral. Color dark greenish-olive on back, 

 lower surface whitish. About 20 abrupt distinct blackish curved 

 bands on side, not reticulated. A dark bar from snout through 

 eye to opercle, and another from below eye over cheek. Length 

 loj^ inches. Crosswicks Creek at Trenton". 



In life pale or dull olive-brown above, marked everywhere 

 with brownish dusky. Upper surface with golden and bronze 

 reflections, in some lights coppery. Side with indistinct dusky 

 lines sloping down f6rward. Lower surface white. A blackish 

 line from tip of snout to eye and continued behind opercle abgve. 

 A blackish streak from lower margin of eye down across cheek. 

 Lips shaded with dusky. Fins all dull orange-red, dorsal and 

 caudal shaded with dull dusky-olive. Iris brow^nsh-oHve-golden 

 above and w^hitish below. A pale median streak from tip of 

 snout to upper base of caudal. Several markings of dusky on 

 side of head like those on flanks. Inside of gill-opening pearl-

This species is the common one in most all of the waters of 

 the state, occurring most everywhere, sometimes in shallow 

 ditches and pools where its retreat is entirely cut off from other 

 waters. It reaches a foot in length and is a good pan-fish. Un- 

 like many of our other fishes they always remain perfectly motion- 

 less or stationary except for such motion as is required of their 

 fins to keep them so. Frequently the glassy goggle-eye may be 

 seen before the rest of the body is made out. When taken from 

 the water alive they are among the most beautiful colored of all 

 fishes but soon fade after death. The color-markings are very 

 soft or diffuse, and the whole body is a perfect mass of shimmer- 

 ing rainbow reflections. They vary somewhat, and some I have 

 seen were quite dark, though this could not have been due alto-
