THE CATFISHES OF VENEZUE1.A — SCHULTZ 263 



anal fin 13.0 (14.4; 12.8); length of longest ray of dorsal 13.0 (15.3; 

 14.0) ; length of longest ray of pelvics 10.8 (9.89; 9.85) ; length of pro- 

 longed ray of pectoral 20.4 (19.3; 18.8) ; least depth of caudal peduncle 

 11.9 (13.1; 9.85); length of caudal peduncle 19.9 (18.9; 21.2); length 

 of longest ray of caudal fin 19.7 (17.6; 17.6); tip of snout to origin of 

 dorsal fin 67.0 (69.0; 66.2); snout to origin of anal 73.2 (74.8; 72.2) 

 snout to anus 68.2 (69.9; 67.2); snout to pelvic insertion 57.9 (57.0 

 56.7); distance from pelvic insertion to anal origin 15.1 (17.4; 15.8) 

 length of maxillary barbel 25.2 (22.6; 20.9); length of lower maxillary 

 barbel 18.3 (16.1; 14.9); length of nasal barbel 21.3 (18.5; 16.7); 

 distance from eye to posterior nostril 2.52 (2.15; 2.09); distance from 

 tip of prolonged upper ray of pectoral fin to pelvic insertion 19.7 

 (21.5; 20.0); length of the prolonged upper pectoral ray beyond tips 

 of branched rays 5.95 (5.59; 4.18). 



The following counts were made, respectively: Dorsal v, 6 (v, 6; 

 V, 6); anal v, 4 (v, 4; v 4); pectoral i, 7-1, 7 (i, 7-1, 7; i, 7-i, 7); 

 pelvic i, 4 (i, 4; i, 4); branched rays of caudal fin always 11. For 

 additional counts refer to table 11. 



Head depressed, body compressed, greatest depth a little in front of 

 pelvics; nasal barbel extending considerably past rear of head; upper 

 maxillary barbel reaching almost to middle of branched pectoral rays ; 

 lower maxillary barbel reaches a little past pectoral insertion; caudal 

 fin a little concave, all other fins rounded; least depth of caudal 

 peduncle is near the middle of its length instead of just behind anal 

 fin base; distance from origin of dorsal fin to midbase of caudal fin is 

 equal to distance from origin of dorsal fin to tip of prolonged upper 

 pectoral ray ; pelvics equidistant from midbase of caudal fin and second 

 third of postorbital length of head; origin of dorsal a little in front 

 of a line through anus, about over tips of pelvics which do not quite 

 reach to anus; length of upper prolonged ray of pectoral equal to 0.9 

 to 1.2 times in the distance from its tip to insertion of pelvics. 



Color. — Everywhere, except on ventral surface in front of anus, the 

 body is profusely brown-spotted; on some specimens these spots are 

 a little larger than the eye, while on others they are smaller; usually 

 the spots are more or less arranged in a row along midsides, with a pale 

 streak above and below more or less setting that series of spots off; 

 however, in females with abdomens distended with eggs, the spots are 

 smaller and not arranged in such definite rows; dorsal surface of head 

 spotted; fins plain grayish, with a little intensification of the pigment 

 basally. 



Remarks. — This new subspecies is like Pygidium banneaui hanneaui 

 Eigenmann, except in color. In hanneaui there is a series of large 

 brown spots well separated from each other along midsides and another
