308 Mr. P. L. Sclater on the Genus Hylophilus. 



In 1874 M. Taczanowski included this species in his list 

 of the birds obtained by Jelski in Northern Peru ; and in 

 1880 Mr. C. Buckley brought home several examples of it 

 from Sarayacu in Eastern Ecuador ; so that its range is by 

 no means restricted. 



The following is a list of the specimens now before me : — 



1. Oyapokj Cayenne iVerdey), Mas. P.L.S. 



2. Bogota, Mus. P. L. S. (type) . 



3. 4. Sarayacu, Ecuador {Buckley), Mus. S.-G. 



•V 16. Hylophilus luteifrons, sp. nov. 

 Fuscescenti-olivaceus, in cauda paulo magis rufescens ; alis 

 intus nigricantibus, extus dorso concoloribus ; f route 

 utrinque usque ad summum oculum anguste lutescenti- 

 fulva ; subtus albidus, in ventre flavido perfusus, pec- 

 tore et hypochondriis saturatioribus ; campterio et 

 subalaribus flavicantibus ; rostro superiore corneo, infe- 

 riore albido : pedibus corylinis : long, tota 3*8, alse 2'2, 

 hujus rem. primi I'l, caudae 1"5. 

 Hab. Guiana Britannica. 

 Mus. S.-G. 



Species prsecedenti affinis, sed froute solum fulvescenti- 

 lutea, pileo antico dorso concolori dignoscenda. 



I base this species on a single skin obtained by Mr. Whitely 

 at Bartica Grove in February 1880. At first I thought this 

 specimen might be a young example of H. ferrugineifrons ; 

 but after a more accurate examination I have come to the 

 conclusion that such is not likely to be the case, although the 

 two species are certainly nearly allied. 



Sect. E. Species supra totce olivacecs.
