THE CYPRINODONTS. 113 



Anal fin commencing about opposite the mirMle 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-branchioe. From Gaboon,

Form resembling that of F. heteroclitus. 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 witli 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. 



Specimen described one inch in length. It may bo that with material in 

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