scales 6——-35——-4._ The end of the pectoral is in line with the origin of 
the first dorsal ray. Radii, D. XXIV, A. VIII, V. IX. 
The head is very obtuse and has a very large eye, beyond whose ante- 
rior rim the extremity of the nasals project buta little way. The spines 
of the premaxillaries project upwards and forwards, but not so far as the 
line of the nasals, and fail by .25 inch of reaching the line of the inferior 
rim of the orbits. The anterior edge of the mandible is in line with the 
anterior rim of the orbit, and the end of the thin upper lip reaches the 
line of the anterior rim of the pupil. 
The diameter of the eye enters the length of the head 3.6 times, and 
the length of the head the total (exclus. caudal) 4.22 times. Opercle 
radiate-ridged. Supraoccipital region much elevated, with lateral ridges. 
Anterior suborbital trapezoid, deeper than long. The size of this species 
is medium; average length, one foot. The color is uniform brownish 
golden. 
From the Wabash River in Indiana. 
Oarptodes cutisanserinus, Cope. 
Species nova. 
This species is near the last, but present various distinctive features. 
These may be summed up as follows: 
The dorsal fin originates mid-way between end of muzzle and basis of 
caudal fin—considerably nearer end of muzzle in C. difformis. The eye 
is smaller, 4.5 times in Jength of head. The spines of the premaxillaries 
project considerably in advance of the line of the nasal bones, and reach 
the line of the lower rim of the orbit. The upper lip is much in advance 
of the orbit, and the end of the same barely reaches the line of the ante- 
rior rim of the latter. Scales 7—37—5. Anterior suborbital bone vertical 
ovate. 
The lips are minutely tuberculate. Operculum and suboperculum ru- 
gose, former radiate. Long rays of dorsal and anal extending a little be- 
yond the basis of the caudal fin. Head four times in length head and 
body. Depth 2.6 in the same. Length, a foot ; color silvery. In a male 
in spring, the muzzle and front are covered with closely set small papil- 
lose corneous excrescences. Radii D. XXVI, V. X, A. VIII. 
From the Kiskiminitas River, Western Pennsylvania. 
Carptodes selene, Cope. 
Species nova. 
Anterior dorsal outline steeply elevated, also the supraoccipital region: 
vertex convex above middle of orbit, concave above anterior rim of same, 
as in the two preceding species. The present fish is intermediate in many 
ways between the two last, and adds characters of its own. Thus the 
anterior suborbital bone is longer than in cither, longer than high, and 
narrowed posteriorly. The orbit is large as in C. difformis, entering the 
length of the head 3.6 times, while the muzzle is more elongate than in 
either. The head is narrowed vertically ; the spines of the premaxillaries 
extend beyond the nasal crests, but do not quite reach the plane of the
