abouts. I have obtained specimens both in Oran and Buenos Aires ; 
but they vary a good deal—the Oran birds being smaller and the 
glossy colour a distinct blue, whereas in the Buenos-Aires bird it is 
green ; and, moreover, the habits of the birds also seem to vary slightly. 
[I am a little doubtful whether Mr. White’s specimens really 
belong to the true 7’. sayaca; but it is very difficult to determine 
accurately the various races of this group of Tanagers. —P, L. S. ] 
25. STEPHANOPHORUS LEUCOCEPHALUS (Vieill.). 
3. Concepcion, Misiones, Arg. Rep., June 27, 1881. 
This bird is not uncommon in Misiones, where it frequents the 
outside of thickets near the open, or sometimes the open itself, 
amongst large weeds, on the seed-pods of which it feeds, but is 
rarely found in dense woods. 
26. TRICHOTHRAUPIS QUADRICOLOR (Vieill.). 
3. Concepcion, Misiones, Arg. Rep., June 23, 1881. 
. San Javier, Misiones, Arg. Rep., June 7, 1881. 
Tris dark. 
I shot these birds in the dense forest. 
27. TACHYPHONUS CRISTATUS (Gm.), 
3. San Javier, Misiones, Arg. Rep., June 6, 1881. 
Tris dark. 
An immature specimen, with no white mark under the throat, as 
is usual in the adult, the whole bird being of a decided ferruginous 
brown, slightly darker on the back and the top of the head. I 
obtained my specimen in the forest on the banks of the river 
Uruguay. 
[1 have never seen examples of this species from so far south.—

28. ARREMON D’ORBIGNII, Scl. 
g. Sierras de Totoral, Catamarca, Arg. Rep., July 29, 1880, 
Iris light blue. 
Met with on the outskirts of the woods, but seldom within them. 
[One of Mr. White’s skins in my collection is marked A. polio- 
notus, Bp. It is, however, probably A. d’orbignii, mihi, although 
I have no Bolivian skins for comparison.—P. L. S. |
