APHELOCOMA UNICOLOR DU BUS, 1847

Type. An unsexed specimen in the Brussels Museum labelled from Tabasco; however, this species does not occur in the state of Tabasco ( van Rossem, 1942). The type locality was later designated as Ciudad de las Casas, Chiapas ( Brodkorb, 1944). The nominate subspecies, A. u. unicolor , occurs in the highlands of Chiapas, Mexico and Guatemala. The larger-billed and generally more purplish A. u. griscomi is found in the highlands of Honduras, El Salvador, and northern Nicaragua ( Pitelka, 1946).
