Pipra pectoralis Lath. Ind. Orn., Suppl. p. lviii (1801 : 
Brazil). 
Euphonia pectoralis Sclater, Cat. B. Brit. Mus. xi. p. 80;

b, c. d ad. „ July 1904. 
Bill black above, grey below, black at tip; tarsi and feet 
dark slate-coloured ; iris brown. 
These examples are identical with others in the National 
Collection from Brazil. I agree, therefore, with Dr. Ihering 
in uniting E. berlepschiana of Bertoni with the present 
species. 
[A very rare bird; one was shot while feeding on the 
fruit of the Palo bianco in July 1904 and another during 
March of the same year.— W. El]

This species appears to me to be divisible into three races— 
Paraguay form, Ecuador form, and Guiana form. The male 
examples from Paraguay are of a darker orange-colour on the 
under surface; E. nigricollis nigricollis, the northern or Guiana 
form, is of a somewhat paler orange-colour below, being in¬ 
termediate between E. nigricollis nigricollis and E. nigricollis
