THE CATPTSHES OF VETSIiEZUEILA SCHULTZ 329 



I lack comparable sizes from tlie Magdalena system. However, tlie 

 greater width of the body through the anal origin on 200-mm. speci- 

 mens from the Maracaibo Basin is 3% in the length of the caudal 

 peduncle as compared to 4 to 6 in examples from Panama and the 

 Magdalena regions. It also appears possible that the lateral plates, 

 including the ones close together, average greater in number for the 

 Maracaibo Basin than for Colombia and Panama. 



The following collections were made in 1942 by Leonard P. Schultz 

 in the Maracaibo Basin of Venezuela. 



U.S.N.M. No. 121085, 6 specimens, 27 to 89 mm. and 246 to 295 mm. in standard 

 length, from a caiio half a mile west of Sinamaica, March 11. 



U.S.N.M. No. 121084, 3 specimens, 273 to 335 mm., from Rio de Los Pajaros, 

 3 km. above Lago Maracaibo, April 30.

The smaller specimens of this species were taken in the rivers, but 

 the largest specimens came from the slightly brackish waters up the 

 mouths of the Rio de Los Pajaros and Rio Agua Caliente, as well as 

 the cano west of Sinamaica.
