160 DENDROCOLAPTID. 
A. cervinigularis on the throat and under surface generally, and there is hardly any 
difference between the colour of the head and back; but specimens of the latter from 
southern localities are somewhat intermediate and not always easy to recognize. They 
have, however, their characteristic marks in a modified degree. 
A. pallidigularis was one of McLeannan’s discoveries, and was described by Mr. Law- 
rence in one of his papers on the birds of Panama *. It is now known to extend as far 
as Nicaragua in our region, Mr. Nutting having obtained a specimen in thick forest 
near Los Sabalos in that country &. On the southern continent Salmon met with it at 
Remedios in the Cauca Valley of Colombia 9, and we have examples from several places 
in Western Ecuador ?°. 
PHILYDOR. 
Philydor, Spix, Av. Bras. i. p. 73 (1824) ; Scl. Cat. Birds Brit. Mus. xv. p. 96. 
Mr. Sclater includes thirteen species in Philydor, only two of which occur within 
our limits. Of these P. panerythrus belongs to the same section as P. rufus, and is 
distinguished by its long tail, which considerably exceeds the wings. ‘The other, 
P. fuscipennis, comes near to P. pyrrhodes, and has a comparatively short tail, as is the 
case with many species of Automolus. 
All the species of Philydor belong to the Neotropical Region, Costa Rica being the 
extreme northern limit of the range of the genus.

P. panerythrus may readily be distinguished from all the other allied species of 
the genus by its cinnamon-coloured wings. It is rather larger than its congeners, 
quite equalling many species of Automolus; the bill, however, is weaker that that of 
the members of that genus, and the nostrils rather more elliptical; the tail, too, is 
longer and not so much rounded.
