Cope. 686 [May 17, 
This species is dedicated to the memory of my late friend, Prof. James 
Orton, as a slight expression of my respect for him as a man, and of my 
admiration for his fearlessness and energy as an explorer. 
59. PROCHILODUS CEPHALOTES, sp. DOV. 
There are several points of affinity to the P. argenteus to be observed 
in the small specimen referred to this species. Radii D. I. 10; A. Ii. 10; 
scales 10—? 41-? depth entering length without caudal fin 2.7 times ; length 
of head three times. The head is wide, the interorbital width being half 
the length, and nearly twice the diameter of the eye. The latter is rather 
less than the length of the muzzle. The pectoral fins are small, not reach- 
ing the ventrals, which in turn do not reach the vent. Dorsal fin with 
three or four transverse rows of brown spots. General color plumbous ; 
above blackish. 
‘Total length .071; length of head .021; to dorsal fin (axial) .024; to 
ventral fin .029 ; to anal fin .045. 
The much larger head and the spotted fins distinguish this fish from the 
P. argenteus, which it resembles in scale and fin formula, and depth of 
body.

Radii; D. I. 10; A. I. 48: scales 24—80+5—23. Head entering total

A species of robust proportions, distinguished by its small rough scales. 
The body is rather deep, and the head wide with very convex interorbital 
region. The depth enters the length less the caudal fin 2.8 times, and the 
head enters the same 3.7 times. The eye enters the head five times, and 
the interorbital region over its convexity 2.5 times. Scales 27-112-28 ; the 
exposed surfaces covered with minute prickles. Radii D. I. 10; A. I. 41; 
V. 7; P. 16, reaching beyond the base of the ventrals, which nearly reach 
the vent. The first anal ray commences below the seventh dorsal ray. 
The top of the head is concave in profile, and the jaws are equal. There 
are two rows of premaxillary teeth, of which the inner consists of very few 
teeth. Oneseries of mandibular teeth including three canines, of which the 
middle one is the largest. Two canines in the premaxillary bone, the an- 
terior much the larger. Maxillary teeth numerous. Maxillary bone ex- 
tending considerably beyond the posterior border of the orbit. Opercular 
bones narrow. 
Color gray, with a broad golden lateral band above the lateral line. In
