ICHTHYOLOGY OF VENEZUELA — SCHULTZ 



175 



U.S.N. M. No. 121620, 98 specimens, 26 to 139 mm., Rfo Palmar near Totuma, 

 about 100 km. southwest of Maracaibo, February 21, 1942. 



Recently I described (Schultz, 1944d) a new species of Petenia from 

 Colombia. In table 20 the species P. kraussi and P. myersi Schultz 

 are compared. H. W. Fowler (Proc. Acad. Nat. Sci. Philadelphia, 

 vol. 97, pp. 133-135, figs. 46, 47, 1945) described Coquetaia amploris 

 from the Rio Coquetd, but this is a synonym of Petenia myersi 

 Schultz; they came from the same river.
