reaching two-thirds of space to ventral. Origin of ventral oppo-

 dusky-leaden band around snout, including tip of mandible, and 

 through eye to base of caudal, where it ends in a black spot. On 

 snout a pale brown shade adjoining black band above. Side and 

 lower surface of body with silvery reflections. Fins pale or dilute 

 brownish, dorsal and caudal a trifle darker. Length i% inches. 

 Crosswicks Creek near Trenton in May, 1904. 



This minnow is found locally abundant. They are generally 

 seen in the smaller creeks and seem to prefer rather still deep 

 water with a gentle current. I have never taken them in the main 

 channel of the Delaware River, though of course they may occur 

 there. The young do' not differ much from the adult, as they 

 have the pronounced black longitudinal band. When preserved 

 a long time in alcohol I notice that the black band of most exam- 

 ples fades to a dark plumbeous. Others vary a great deal in re- 

 gard tO' the lateral line, as in some it is nearly complete. It does 

 not seem possible to^ me as yet to separate the fry from those of 

 procne, or those which would appear to be the young of the latter. 

 They are abundant in Crosswicks Creek and in the Passaic River.

Close to Notropis bifrenatits but distinguished chiefly by its 

 long caudal peduncle and tail, large brown-edged dorsal scales, 

 and the plumbeous lateral band. 



I have no New Jersey examples.
