31. HAPLOCHILUS MELANOPS, Cope. 
Sp. nov. ; 
First dorsal ray opposite middle of anal. Scales in. 31 transverse, and 
9 longitudinal series. Radii D. 1.6, A. 1.8, V. 6. Head 3.66 times in 
length, exclusive of caudal fin; eye 3 times in head, 1.6 times in inter- 
orbital width. Dorsal and anal fins each short, each measuring ‘less than 
half the distance from their first ray to to the basis of the caudal fin. Cau- 
dal narrowed, rounded. ; 
Above, yellowish brown, scales darker edged, a few longitudinal lines 
on some dorsals ; in some specimens, a median brown dorsal line. Dorsal 
and caudal fins each with a row of black dots across the middle, and one 
near the margin. Belly golden. Length 1.5 inches, the largest size. A 
blue-black spot below the eye in most specimens. 
Very abundant in still waters of the Neuse basin, Wake Co., N. Ca. 
ESOX, Linn. 
32. Esox aFrFinis, Holbrook. 
Ichth, 8. Carolina, 198, Pl. xxviii. fig. 1. 
This species is near to but distinct from the ZF. retiewlatus of the North. 
In life it is of a bright light emerald green, with dark reticulations. 
Common in the Neuse River. 
33. Esox RAVENELII, Holbrook. 
Ichthyology South Carolina, p. 201, PI. xxvii., fig. 2. 
Length from muzzle to pectoral equalling length from pectoral to ven- 
tral fin; latter space embracing 87 transverse series of scales. From end 
muzzle to orbit less than from orbit to opercular border. Br. XIII. D. IL. 
12. Brown above with brown cross-bars; edge of dorsal and caudal 
fins red. 
This species is near EZ. americanus, but has a relatively longer head. 
Size and color similar. From the Catawba River, N. Ca. 
. SEMOTILUS, Rafinesque, 
Putnam, Cope. ; 
34. SEMOTILUS CORPORALIS, Mitchill. 
From the French Broad, Catawba, Yadkin, Deep, and Neuse Rivers. 
CERATICHTHYS, Baird. 
Four species of this genus were observed, of which two are new to 
Zoology. They both belong to 
Sect. II., mouth more or less inferior, small ; teeth 4-4 or 4. 1.—1. 4; 
size small. ; 
Depth less than length head ; last dorsal ray more than half first ; muz- 
zle narrow, beards long ; small ; C. LABROSUS. 
sent thischaracter. There are no pseudo-branchiae. From Gaboon, W. Africa, P. B. DuChaillu. 
It may be stated in this connection that the genus called Lycocuprinus by Peters, for Haplo- 
chiluid fishes with pseudo-branchie, was previously named Epiplatys by Gill. The type of the 
Jatter, E. sexfasciatus (1862), from Gaboon, is different from the Z. (L.) sexfasciatus (1864), the 
type of Peters. The latter may, therefore. take the name of E, infrafasciatus (1865), which 
Guiuther gave the same species, subsequent to Peters.
