lion ; also, the iris above and below the orbit. The dorsal fin has a large 
black spot on the posterior half; the fin is anteriorly vermilion. The 
tail has a rather broad black posterior margin, and a wide vermilion 
crescent following it into the points of the fin; base of the fin pale. Anal 
and ventral fins with milky pigment. 
Small horny tubercles appear on the upper surface of the head in spring, 
as in the species of Hypsilepis. 
In this case I have assigned this species to its genus in accordance with 
its technical characters, but it is probable that it will be necessary to 
change the arrangement at some future time,—when the structure of these 
fishes is better know. 
The P. pyrrhomelas is the most abundant fish in the tributaries of the 
upper Catawba River, North Carolina. 
ALBURNELLUS, Girard. 
Several species of this genus were obtained, and may be compared with 
others already known, as follows : 
I. Ventral fins extending beyond dorsal, reaching anal. 
Scales 5—36—2 ; dorsal much elevated. A. 8. A. ALTIPINNIS. 
II. Ventrals extending to opposite last dorsal ray ; not to anal. 
a. Scales above lateral line 5—6. 
f. Scales large, lateral line 33. 
Orbit large. A. MEGALOPS.

Spec. nov. 
This species is much less elongate than such typical forms of the genus 
as A. jaculus, etc. ~The head is short, but not wide. Orbit very large, 
diameter exceeding muzzle, entering length of head 2.75 times, one-third 
greater than the interorbital width. Head 4.33 times in length to basis of 
caudal, depth five times in same. Anterior dorsal radii unusually pro- 
longed for the genus, equal just half distance from the base to end of muz.- 
zie. D.I.8. A. 1.9. The pectorals do not quite reach the base of the
