35, 3 to 4% above and 3 below lateral line, with 10 to 12 in

i, 8 or 9; scales 33 to 37, with 4% or 5 above and 3 or 4 below 
lateral line; 11 to 13 scales in front of dorsal fin; gill rakers on 
first gill arch 6 or 7+ 9 or 10; 9 or 10 dark cross bars on sides and 
a dark lateral band; basal third of caudal fin brownish in adults. 
10a. Black cross bars on half-grown and many adults ending abruptly 
in black lateral streak as enlarged round black spots, in others 
the bars faint, especially on breeding females; scales 33 to 36. 
Characidium chupa chupa, new species and subspecies 
10b. Black cross bars usually extending a little below the blackish 
lateral band and not intensified into round black blotches; 
scales 35 to 37.

CHARACIDIUM BLENNIOIDES Eigenmann 
Characidium blennioides EIGENMANN, Ann. Carnegie Muss vol/ 6) Nos ps 37: 
1909 (Erukin, tributary to Potaro above Kangaruma; Tukeit; creek above 
Potaro Landing; Tumatumari; Crab Falls; Amatuk). 
Through the courtesy of J. T. Nichols, American Museum of Nat- 
ural History, I was able to examine 5 specimens that probably belong 
to this species. They were collected at Mount Duida, Venezuela. 
CHARACIDIUM DECLIVIROSTRE Steindachner 
Characidium declivirostre STEINDACHNER, Denkschr. Akad. Wiss. Wien, vol. 93, 
p. 31, 1917 (Rio Coquenan, tributary to Rfo Caroni, in Venezuela). 
CHARACIDIUM CATENATUM Eigenmann 
Characidium catenatum HiGENMANN, Ann. Carnegie Mus., vol. 6, No. 1, p. 40, 
1909 (Warraputa; Rockstone sandbank; Crab Falls, all British Guiana) ; 
Indiana Univ. Stud., vol. 7, No. 44, p. 10, 1920 (Rio Guaire near Caracas; 
Rio Tuy, Concejo, Venezuela). 
I have examined two of Eigenmann’s specimens, Ind. Univ. No. 
15142, collected by Pearse in the Rio Guaire, and find very small 
lateral points basally on some of the teeth. Through the courtesy of 
J. T. Nichols, American Museum of Natural History, I examined 
two specimens of this species from Mount Duida, Venezuela. 
2 C. caucanum (paratype, U. S. N. M. No. 79183) and C. phorocephalum (cotype, Ind. Univ. No.12704) 
have been studied; also additional specimens (U. S. N. M. Nos. 120144, 120145, 120146 and 120209). From 
this series it is concluded that the coloration is variable, as the young and half grown have vertical bars that 
disappear on adults, usually completely lacking on mature females. The number of scales is variable, 
32 to 35. Thus, I conclude that phorocephalum is a synonym of caucanum.
