| THE CYPRINODONTS. 118 
Anal fin commencing about opposite the middle of the dorsal. Cheek scaly, 
operculum smooth. Scales of body in 36 transverse, and 12 longitudinal 
series. Radii D. 12, A. 10 or 11, extending more than half way from basis 
of first ray to basis caudal. Length of female four inches. Color uniform 
light brown, yellowish below. Most of the specimens of this species (seven) 
are females, and in them the oviducts are prolonged in a tube to near the 
extremity of the first ray of the anal fin. Several have many well developed 
eggs in the former. Small, faintly cross-banded specimens, perhaps males, 
do not present this character. There are no pseudo-branchiw. From Gaboon,

B. 6; D.18; A. 18; V. 6; Ll. 36; Ltr. 11. 
Form resembling that of F. /eteroclitus. Body compressed ; head broad, 
depressed, crown flat. Snout short, rounded from the eye forward, blunt; 
chin steep. Mouth of medium size, directed obliquely upward; lower jaws 
longer, firmly joined ; upper short, protractile. Teeth slender, pointed; outer 
series larger, hooked, appearing slightly expanded near the apex; inner simi- 
lar to outer, very small, in bands; pharyngeal with a shoulder. Eye large, 
nearly twice the snout, two fifths of the head, little less than the interorbital 
space. Dorsal origin midway from middle of eye to base of caudal, slightly 
forward of vent. Anal origin nearly under middle of base of dorsal. Scales 
small. Caudal convex. 
Olivaceous, edges of scales darker. Top of head darker, crossed by a 
lighter band in front of the eyes. Opercle silvery, crossed by a darkish 
streak behind the eye. Belly whitish or silvery. A faint band of silvery 
from the operculum to the caudal along the middle of the side. Five or six 
broad blotches of brownish across the flanks, separated by rather wider 
spaces of the lighter color. <A vertebral darkish streak, more distinct be- 
hind the dorsal; a similar line between anal and lower edge of caudal. A 
band crosses the caudal near its base. Darker color shows faintly through 
the silvery band on the flanks,

better condition, and a knowledge of the sexual peculiarities, a different dis-
