140 REPORT OF NEW JERSEY STATE MUSEUM. 
reaching two-thirds of space to ventral. Origin of ventral oppo- 
site that of dorsal, and depressed fin reaching anal. Color straw- 
brown, scales on back edged with brown. A shining dusky or 
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 15% 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 exan- 
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.

Minnow. Minnie. Swallow Minnow. 
Close to Notropis bifrenatus 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.
