Centrites niger, Scl. et Salv. P. Z.S. 1867, p. 987, et 1868, p. 569. 
Niger: dorso castaneo: remigum primariorum pogoniis internis 
albicantibus : long. tota 5°5, ale 3°2, caude 20. 
Fem. Fusea: dorso luride castaneo: primariis, sicut in mari albi- 
cantibus sed cinnamomeo tinctis. 
Hab. Peruvia alta (Whitely). 
Obs. Centrites niger remiges intus nigros unicolores ostendit. 
Two pairs of this Centrites were collected at Tinta. D’Orbigny 
does not appear to have recognized its distinctness from the common 
species of the Argentine Republic, of which we have examined many 
specimens. Besides the difference in the wing-feathers, the present 
species is larger, and has the back of a rather lighter chestnut. Mr. 
Whitely’s former specimen from Salinas belongs also to the present 
species.
