CHARACINIDAE FROM VENEZUELA—SCHULTZ 273 
Counts were made on certain specimens of Hydrolycus in the United 
States National Museum, and these data are recorded in table 9. 
The following specimen was collected for me through the courtesy 
of Dr. Walter Dupouy, director of the Museo de Ciencias Naturales, 
Caracas: 
U.S. N. M. No. 121385, a specimen, 240 mm. in standard length, collected by

The recent study by Paulo de Miranda Ribeiro (Papeis Avulsos 
Dept. Zool. Sci. Agr. Séo Paulo, Brasil, vol. 1, art. 18, pp. 159-174, 
figs., 1941) of the genus Chalcinus did not prove very satisfactory, as 
in some cases his counts in the key are not in agreement with the 
descriptions of the species. 
18 According to Myers (Stanford Ichth. Bull., vol. 1, No. 5, p. 170, 1940), Triportheus replaces Chalcinus.
