CHARACINIDAE FROM VENEZUELA—SCHULTZ 300 
U.S.N.M. No. 121451, a specimen 65 mm. in standard length, 
taken by L. P. Schultz, G. Zuloaga, Roger Sherman, and William 
Phelps, Jr., May 12, 1942, in the Rio Gu4rico and tributaries between 
San Sebastian and San Casimiro, Estado de Aragua, Venezuela. 
The following collections, made by Dr. William Beebe, were lent 
to me for study and report: 
A specimen, 86 mm., Caripito, Venezuela, 1942. 
Four specimens, 41 to 45 mm., Caripito, Venezuela, 1942. 
Seven specimens, 26 to 35 mm., Caripito; Venezuela, 1942. 
ASTYANAX SUPERBUS Myers 
Astyanax superbus Myzrs, Stanford Ichth. Bull., vol. 2, No. 4, p. 92, fig. 2, 1942 
(brook tributary to Rio Tamanaco [tributary to Rio Paye, Rio Portuguesa 
drainage], Camoruco, 20 km. northeast of San Carlos, Venezuela). 
U.S.N.M. No. 121454, 5 specimens, 70 to 95 mm. 1n standard length, 
collected by Leonard P. Schultz, March 31, 1942, in the Rio Torbes, 
1 km. above Tariba, Venezuela (Orinoco system). 
ASTYANAX MAGDALENAE Eigenmann and Henn ~ 
Astyanax magdalenae EIGENMANN and Henn, Ann. Carnegie Mus., vol. 10, p. 89, 
1916 (Girardot). 
The specimens from the Maracaibo Basin have a few small pre- 
ventral scales along the midline of the breast and a similar arrange- 
ment along the predorsal midline of back; the humeral spot is black, 
larger than pupu, with a whiff of smckelike pigment off the posterior- 
dorsal side, this black spot being set off by a large pale area in front 
and behind; the pale area behind the black spot is margined posteriorly 
by an intensification of pigment; the dark or silvery lateral band begins 
behind the wide pale area behind the black humeral spot; the caudal 
spot is‘black, always very intense, horizontally oval, but not continuing 
on middle caudal fin rays; the profile is slightly concave near a vertical 
line through rear of orbit then convex to dorsal fin; depth 2.0 to 2.2 
and head 3.4 to 3.6, in standard length; the distance from dorsal origin 
to tip of snout is a little shorter than from dorsal origin to midcaudal 
base. Table 26 gives numerous counts made on this species from the 
Maracaibo Basin. 
It is likely that the population of this form in the Maracaibo Basin 
is Statistically different from that in the Magdalena Basin, but no speci- 
mens of the latter are availabie for study at present, so it seems best to 
identify my specimens as A. magdalenae. 
The following collections were made by Leonard P. Schultz m the 
Maracaibo Basin of Venezuela during 1942: 
U.S.N.M. No. 121424, 19 specimens, 40 to 92 mm. in standard length, taken in 
the Rio Socuy, 3 km. above the mouth, February 24. 
U.S.N.M. No. 121480, 6 examples, 68 to 94 mm., from the Rio Motatdn at 
bridge, 22 km. north of Motatén, March 17.
