Depth of body 23 to 24 in the length, length of head 3. Snout a little shorter than eye, the diameter of 
which is 3 to 34 in the length of head; interorbital width 23 in the length of head. 25 or 26 scales in 
a longitudinal series. Dorsal 10-11; longest rays equal to the base of the fin (¢) or a little less (? ), 
#(d)or 4(¢) the length of head, scarcely longer than the longest anal rays. Anal 10-11. Pectoral 
4 the length of head. Caudal subtruncate. Least depth ef caudal peduncle 2 the length of head. 
Body with irregular dark cross-bars and an interrupted lateral band, these markings scarcely distinct 
in males ; the caudal fin and sometimes the dorsal and anal with a narrow dark edge (in the males), 
the dorsal with a small dark spot on the posterior rays (in the females).

5. ZOOGONETICUS, Meek, 1902. 
Zoogoneticus, Meek, Publ. Columbian Mus., Zool. v. 1904, p. 109. 
Viviparous. Anal tin of the male with the anterior five or six rays short, stiff, and subequal, separated by a 
more or less distinct notch from the rest of the fin. Mouth rather small, with short lateral cleft ; rami 
of the lower jaw firmly united; minute teeth in bands, with an outer series of enlarged, fixed, conical 
teeth. 
This genus comprises four species, from the Rio Lerma System and the Valley 
of Mexico. It is very closely related to Funduli of the type of F. punctatus, 
F. nachycephalus, &c.
