broad leaden band, which narrows behind on the caudal peduncle and 
becomes a dusky band, ending in an ill-defined caudal spot. There is a 
narrow dorsal band. The top of the head and snout, as well as the 
lower jaw, are dusky. The belly is pale. 
The dorsal and caudal are red, with more or less dusky. There is no 
dark spot at the base of the dorsal, as in some species of Lythrurus ; but 
there is a distinct black spot on the upper part of the anterior rays of 
the dorsal. There is a similar black spot at the distal ends of the ante- 
rior anal rays. The anterior rays of the pectorals are dusky. 
Large numbers of this species were collected at Enterprise. The 
largest specimens have a total length of 24 inches. 
41. Minnilus bellus, Hay, sp. nov. (No. 27,426.) 
Adults of this species resemble much the young individuals of 
Notemigonus chrysoleucus. 
The body is short, deep, and considerably compressed. The dorsal 
region is elevated. Depth contained in the length about 3? times. 
Head short, in length of body from 4 to 44 times. Muzzle short, rather 
pointed; the profile in adults concave; mouth quite oblique, large, the 
maxillary reaching back to the anterior rim of the orbit; the lower jaw 
rather longer than the upper. The eye moderate, 33 in the head. 
The lateral line is much decurved anteriorly. Scales 7 or 8-40 to 
42-3, crowded forward, higher than long, about 25 in front of the 
dorsal. Teeth 2, 4-4, 2, ‘‘sharp-edged”, but with a “masticatory sur- 
face! 
Fin-rays, D. I, 8; A. I, 10-11. Dorsal situated midway between the 
tip of the snout and the origin of the caudal, wholly posterior to the 
ventrals, nearly twice as high as long, its length being contained in the 
head 12 times. Anal contained in the head 14 times, a little higher 
than long, ventrals reaching the vent, the pectorals not extending to 
the ventrals. Caudal peduncle very little longer than the head, and 
rather slender. 
Color (in spirits) somewhat dusky above, with a narrow, dark dorsal 
line; sides silvery, with a dull, leaden line along the caudal peduncle. 
Occasionally, in some of the most highly colored specimens, a few scales 
on the side are widely margined with black, so that the sides appear 
splotched. The lower part of the body is in life almost flame-color. 
All the fins orange, at least at their bases. At least the tips of the 
dorsal, ventral, and caudal jet-black. No spot at the base of dorsal. In 
some adults the whole dorsal has black pigment mingled with the 
orange, besides having the rays tipped with black, and the distal half 
of the ventrals and anal black. Very few specimens are without the 
black tips to the fins, so that this becomes a distinctive character. 
Evidences of the existence of tubercles were observed on the heads of a 
few specimens.
