THE CATFISHES OF VETSTEZUEILA SCHULTZ 299 



Color. — Grayish above, paler below, with a blackish irregular 

 band along the midsides that joins with four or five blackish saddles 

 dorsally and has four or five dark projections ventrally; first dorsal 

 saddle under front of doi-sal fin, second at rear of dorsal fin, third 

 in front of adipose; fourth behind adipose; fifth at base of caudal 

 fin rays; these saddles enclose pale areas dorsally, ventrally the pale 

 areas are not enclosed by the dark bars; usually three dark bars on 

 pelvics and four across pectorals, these bars difl'use in the immatui'e 

 so that the fins are evenly blackish except distally pale; dorsal with 

 kregular, wide bars in adults, plain blackish in young, tips of first 

 dorsal rays pale; caudal similar to dorsal but with four or five dark 

 bars on lower ray; tips of rays of upper lobe of caudal fin pale. 



Remarks. — This new form differs from all other species referred 

 to the genus Pseudancistrus in having only three plates between 

 the dorsal and adipose fins and in its color pattern. Other members 

 of the genus have four or more plates between dorsal and adipose. 

 The greatly depressed and very wide head, compared with the short 

 body, is a characteristic feature of this new species. 



Named torbesensis after the stream in which it was found. 



PSEUDANCISTRUS COQUENANI (Steindachner) 



Ancistrus (Pseudancistrus) coquenani Steindachner, Denkschr. Akad. Wiss. 

 Wien, vol. 93, p. 90, pi. 11, figs. 3 to 5, 1917 (P»fo Coquenan, tributary to 

 Rio Caroni in Venezuela). (Based on A. guntheri Regan, 9 ; see table 17 

 for measurements.) 



PSEUDANCISTRUS YARAM (Steindachner) 

 Ancistnis {Hemiancistrus) yaravi Steindachner, Denkschr. Akad. Wiss. Wien, 

 vol. 93, p. 87, 1917 (Rfo Coquenan, Venezuela). 



See table 17 for measurements. It is doubtful that this and the 

 preceding species are correctly placed. Steindachner does not 

 mention certain characters needed for this identification. They 

 are placed in Pseudan.cistrus because the rami of the jaws are con- 

 tained fewer than 1% times in the interorbital, which is flattish.

 Plate 9, A, B 



Holotype.—U.S.lSl.M. No. 121036, a male 78.6 mm. in standard

 Rio La Grita, below La Grita, Catatumbo system, Maracaibo Basin. 



Parafypcs.—V. S. N. M. No. 121037, 4,820 specimens, 9 to 79 mm.

 same data. All these were taken in very swiftly running water 

 amons; rubble to gravel.
