324 TANAGRIDA. 
only one, Arremon aurantiirostris, is found within our area, where, however, it is widely 
distributed. The South-American species are chiefly from the Subandean regions, but 
the best known of all, A. stlens, spreads over the whole of the eastern portion of the 
continent, from Guiana and Amazonia to Brazil. 
In structure and coloration Arremon is very homogeneous. The bill is straight, 
rather high, short, and conical, with an obsolete subterminal maxillary notch. The 
wings are short and rounded; the tail also rather short and much rounded; the tarsi 
are somewhat long, appropriate to a semiterrestrial habit. Most of the species have a 
black head, and in many of them is a vertical median cinereous stripe; the under- 
surface is white, and many species have a conspicuous black pectoral band. The bill 
is often of a rich orange or yellow; the back is either olivaceous or grey. 
The species all appear to frequent the denser forests, where they are to be found in 
the underwood or on the ground.

Lafresnaye’s description of this species was based upon Panama specimens obtained 
by the French collector Delattre!. We have since both received skins from the isthmus 
and observed the bird in that region. In May 1873 Salvin found a nest in the forest 
near Obispo Station, which was placed on the ground and prettily screened by an 
overhanging frond of an Adiantum. ‘This nest contained young, which were not 
disturbed. 
From Panama A. aurantiirostris has been traced northwards to South Mexico, where, 
however, it is not common, having been found at Playa Vicente alone by M. Boucard 5.
