I am only acquainted with this species from Mr. Cassin's 

 original notice of the type-specimen, which is in the Museum of 

 the Academy of Natural Sciences of Philadelphia. He describes 

 it as follows : — 



" Form. — Generally short and robust ; feathers of the head but 

 little elongated, wings and tail short. A strict congener of B. ma- 

 crorhynchus and pectoralis. 



" Dimensions. — Total length 7| ; wing SS ; tail 2-8. 



" Colours. — Tail with a central transverse white bar. Breast 

 with a narrow band of black, immediately succeeded by another 

 much \\-ider of dark chestnut-bro^-n ; throat and abdomen white, 

 which is the colour also of the frontal feathers and of the internal 

 webs of the primaries at their bases, and of a narrow collar on 

 the back of the neck. Entire superior sui'face of the head, body, 

 wings and tail black, with a greenish gloss. Tail mth a band of 

 white most observable on the inner webs of the feathers and 

 narrowly edged with white at its end. Flanks striped with the 

 same dark brown as the broader belt of the breast. 



" Hab. Venezuela. 



" Obs. — A bird resembling generally the several species of 

 which B. macrorhynchus is a representative, but immediately 

 recognizable by the white in its tail, and its smaller size. I have 

 seen only the specimen now described. ^^ 



This bird appears certainly quite distinct from any other of the 

 genus.

 tus albus vitta pectorali lata nigra ; rostro pedibusque nigris. 



Long, tota 6*0; alse 2'9 ; caudse 2'0. 



Hab. in Cayenna, Surinamo et Guiana (Wagl.) ; Para (Wallace). 



This is the smallest of the five species of pied Barbels we are 

 at present acquainted with, and to be recognized at once by the 

 round white spots on the head, which are not found in any of 

 the preceding.
