Girardinus garmani Eigenmann, new species. f * 
Type, No. 9661, Ind. Univ. Mus., one male, 35 mm., Dinar del Rio. Cotypes, one male, 35 nun., 
Pinar del Rio; one male, 38 mm., Palacios. 
D. 9; A. 9; scales 29; depth 3.4 to 3.6; head 3.6 to 3.8. Body compressed; head truncated, lower 
jaw nearly vertical; mouth ver} r small, lips thick, teeth in a single series in each jaw, sloped as in G. 
metallicus, very movable, interinaxillaries and dentaries not united; eye as long as snout, 2.5 in head, 
equal to interorbital; origin of dorsal a little nearer pectoral than base of middle caudal rays; dorsal 
rounded, small; dorsal, caudal, and pectoral of about equal height, equal to distance of pectoral from 
eye; anal process 2.5 in length, serrate near its tip behind and with a clasper at its end; ventrals 
very small, reaching to the anal; ventral surface colorless except a black line from anal to caudal; 
scales of side with a dark margin of increasing width toward back; a dusky dorsal streak; head in 
front of eye dark above and below; region below eye colorless; a well-defined black spot on base of 
last 5 dorsal rays; first dorsal ray black ; anal process blackish on basal half, a small indistinct black 
spot on distal half of last anal membrane and extending at times on neighboring regions; sides 
without streaks or bars. 
This species differs from G. metallicus and G. denticulatus in being entirely without, streaks or 
spots or bars on the sides, in the number of anal rays, and in other characters. 
TOXUS Eigenmann, new genus. f. 
Toxus Eigenmann, new genus of Pieciliid; u ( riddlei ). 
This genus differs from Glaridiclithys in its narrow teeth, from Girardinus in having its jaws firmly 
joined. 
Toxus riddlei Eigenmann, new species, f* 
Type, No. 9656, Ind. Univ. Mus., a female, 59 mm. long, from San Cristobal. 
Cotypes: 1 female 66 mm. long, and 2 males 33 and 34 mm. long, from San Cristobal. Head 4; 
depth 3.4; D. 9; A. 10; scales 28; origin of dorsal midway between base of middle caudal rays and origin 
of upper pectoral ray and over thirteenth scale of lateral line; origin of anal below eleventh scale; fins 
moderate; longest dorsal ray equaling length of head without snout; eye equaling snout, little more 
than 3 in head; interorbital convex, equaling snout and eye; profile slightly curved; outer row of 
teeth movable, spear-shaped, not very closely set, brown-tipped, a band of minute teeth behind them; 
a dark lateral band crossed by about 6 indistinct dark crossbands; scales of sides with a light center 
and a narrower or broader margin of dark, forming reticulations; a dark streak extending down between 
eye and angle of mouth ; rest of lower side of head and belly white; pectoral colorless; caudal faintly 
dusky; anal with a faint dark band through the middle, the tips and base colorless; dorsal dusky. 
Male much smaller, the color contrasts sharper; about 7 well-marked dark crossbands in the 
larger specimen; dorsal tipped with dusky, a black band from base of last dorsal rays forward toward 
basal third of fourth dorsal ray; in the larger specimen a series of dark spots on dorsal rays on a level
