THE CYPRINODONTS. 41 
Radical differences in the structure of jaws and teeth and the presence of 
the viliform bands behind the outer series of teeth on the jaws compels the 
separation of this genus from Girardinus. 
Glaridodon uninotatus.

Body elongate, compressed, arch of back low; caudal pedicel of mod- 
erate depth. Head short, two ninths of the length to the base of the caudal, 
slightly arched across the forehead. Mouth wide, arched in outline, directed 
upward ; lower jaws longer, strong, firmly united ; upper shorter, protractile. 
Snout short, blunt, two thirds of eye or half of interorbital space; chin 
steep. Teeth in the outer series stout, varying in shapes, slightly swollen at 
the base, broadened and shovel shaped at the apex, hooked, firmly set ; in 
the inner series small, pointed, slightly broadened near the summit, hooked. 
Pharyngeal teeth slender, hooked, with a shoulder. Eye large, longer than 
snout, two thirds to three fourths of forehead, two fifths to one third of head. 
Dorsal origin near the middle of the total length, over third or fourth rays 
of anal in the female. Anal of male farther forward; anal process very 
long, one third of the total length of the fish. Ventrals and pectorals small ; 
latter reaching a vertical from the origin of the anal in the male or the bases 
of the ventrals in the female. Caudal large, subtruncate or slightly convex 
on hind margin. Scales large. Intestine more than twice the total length. 
Back olivaceous, sides silvery, belly lighter. A black spot on the twelfth 
to the fourteenth scales behind the head, above the vent, on the middle of 
the flank. Poey says of fresh specimens, “la couleur est d’un brun verditre, 
avec une grande tache arrondie sur les flancs, i l’'aplomb de l’anus; un cercle 
noir entoure l’orifice anal ; le trone porte un réseau de points pigmentaires, 
qui disparaissent dans l'eau de vie.” He found twenty-four embryos in one 
female. Our description is taken from his types. 
Largest female three and three eighths and largest male one and seven 
eighths inches.
