White met with a male of this species in September 1881, at San Pedro, in the province of Santiago. Burmeister found it near Mendoza in the valleys of Sierra de Uspallata. 65.

Of this species, discovered by Dr. Burmeister near Mendoza, Mr. Barrows writes:--"Only met with on the Sierra de la Ventana, where it was abundant in flocks, some of which numbered as many as a hundred individuals. When found near the base of the sierra they were almost always associated with the common _Zonotrichia_. Although most of them had not finished moulting, they were constantly singing, and seemed perfectly contented with their desolate surroundings." 68. PHRYGILUS DORSALIS, Cab.
