the chin. Females three and one fourth, and males one and three fourths 
inches.

Girardinus denticulatus sp. n. 
B. 5; D.9; A.1l1; V.6; P. 12; Ll. 29; Ltr. 9; Vert. 18+17. 
This form is closely allied to G. metallicus ; it is distinguished by the 
presence of bands of denticles behind the outer series of teeth on the jaws 
and by the coloration. 
Light yellowish or olivaceous brown, edges of scales darker, cheeks, 
throat, and belly silvery. A band of silvery more or less distinct from the 
upper angle of the opercle to the middle of the base of the tail. Above this 
band the back is darker; below it the flanks are light or silvery. None of 
the specimens show the vertical silvery bars so characteristic of G. mefallicus. 
On most a clouded blotch crosses the greater part of the dorsal, becoming 
more intense backward. A similar blotch, but less vivid is sometimes seen on 
the anal. Rarely a dark line extends from the occiput to the dorsal. Top of 
head dark.

Girardinus creolus sp. n. 
Plate V. Fig 9, teeth. 
B. 5; D.10; A. 11; V. 6; P. 16; Ll. 30-29; Ltr. 9; Vert. 14+16. 
Body rather stout, compressed behind the head, caudal pedicel moder- 
ately deep. Head broad, as wide as deep, one fourth of the length to the 
base of the caudal, about equal to depth of body at dorsal origin, flattened on 
the crown. Snout short, not as long as the eye, broad, truncate. Mouth 
wide, directed upward, shaped as in Peecilia; mandibles short, loosely joined ; 
intermaxillaries shorter, protractile. Lips thick. Outer series of teeth larger, 
broad and hooked toward the apex, constricted toward the base, movable ; 
inner series in bands, small, pointed, slightly broadened toward the point; 
pharyngeal small, slender, some with a shoulder. Eye large, nearly one 
third of the head or half of the forehead. Dorsal origin about midway from 
base of pectoral to base of caudal, above the middle of the anal. Anal of 
the female not reaching as far backward as the dorsal; fin farther forward on 
the male, behind the ventrals, equal one third of the total length, modified 
to form an intromittent organ with a clasper at the end. Ventrals small, 
reaching the origin of the anal. Pectorals reaching the bases of the ventrals
