A. cermnigularis 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 ®, and we have examples from several places 

 in Western Ecuador ^*'.

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 Eica 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.
