Parodon apolinart Myers, Proc. Biol. Soc. Washington, vol. 48, p. 66, 1930 (Guai- 
caramo, Rio Guavio, Colombia); Stanford Ichth. Bull., vol. 2, p. 93, 1942 
(Rio Guarico, at El Sombrero, Gudrico, Venezuela). 
The following specimens were collected in Venezuela during 1942: 
U.S.N.M. No. 121298, 7 specimens, 45.5 to 85 mm. in standard length from 
the Rio Gudrico and tributaries between San Sebasti4n and San Casimiro on 
May 12, by L. P. Schultz, G. Zuloaga, Roger Sherman, and William Phelps, Jr. 
U.S.N.M. No. 121296, a specimen, 120.5 mm., collected by Leonard P. Schultz, 
March 31, in the Rio Torbes, 1 km. above Tériba, T4chira, Orinoco Basin. 
These fish, living in the swift waters of mountain streams, are 
difficult to capture. Upon the slightest disturbance, they dart among 
the stones and hide. 
See table 12 for measurements of this and the next species.

21 Steindachner, Denkschr. Akad. Wiss. Wien, vol. 93, p. 25, pl. 5, fig. 1, 1917, records Parodon tortuosus 
Eigenmann and Norris from the Rio Coquenan in Venezuela. His figure does not agree with his measure- 
ments in the table on page 27, especially in regard to the origin of the dorsal fin. Probably the specimen 
from the Rio Coquenan is suborbitale or ‘a subspecies of it.
