comparison. The pectorals do not reach the ventrals, the maxillary 

 barbels reach to the ventrals, or are shorter. The eye is four and one- 

 halt times in the head and a little less than the interorbital, the anal 

 has eleven to thirteen rays.

The larger one of these specimens agrees in all but two points with 



Boulenger's description of Pimelodiis pulcher. Boulenger says: "The 



band of teeth in the upper jaw is of moderate 



breadth, without prolonged lateral portion" and 



"Dorsal . . . with a strong serrated spine." 



In the larger specimen the depth of the premaxil- 



lary band of teeth is three and one-half times in its 



width, and there is a backward projecting angle. 



The dorsal spine has seven recurved notches along 



Fig I Pseu- *^^ entire posterior face and two on the anterior 



dopimelodus pul- face near the tip. The pectoral spine has nine re- 



cher Boulenger. curved hooks on its anterior margin, those on its

 the lobes of the caudal at the top of the middle rays, which are light. 

 The larger one is colored nearly identically like the specimen of 

 pulcher figured by Boulenger (Proc. Zool. Soc, 1888).
