T h is new species will be readily distinguished from all known grooved-billed A^aris by the white bands on
the bill and the blood-red spot on the rump. Its nearest allies are Pter. stdcatus and Pter Derbmnw
but independently of the blood-red spot on the rump already alluded to, it may always be distinguished from
those species by its shorter bill, wider gape, and by the circumstance of the four middle tail-feathers being
tipped with brown, while in Pter. Derbianm the two middle tail-feathers only are thus tipped.
I cannot close this paper without offering my warmest thanks to N. C. Strickland, Esq., for his kindness
in lending me the present species to figure from, and who has at all times rendered me'every assistance in his
power by placing at my disposal for scientific investigation any species contained in his collection. The one
in his possession, and another in the Royal Museum at Leyden, are, as far as I am aware, the only examples of
this species at present known. I have to regret that Mr. Strickland could give me no information as to what
part of South America his specimen was received from, but circumstances induce me to believe that it is from
the Cordillerian Andes.
