ON SOME BIRDS FROM NORTH-WEST ECUADOR. 



BY ERNST HARTERT. 

 (Plate V.) 



1. Neocrex uniformis sp. uov. 



Differs from its nearest ally Neocrex erythrops {Cat. B. Brit. Mns. XXIII. 

 {). 163) as follows : — 



Ujiperside browner, somewhat more rnfons, less olive. Lower abdomen slaty 

 grey, without bars ; flanks brownish, without bars ; thighs without traces of bars ; 

 under wiug-coverts white with slaty grey bases, but without bars ; only one or two 

 of the central feathers with a riuglike slaty mark ; under tail-coverts pale buff, 

 not barred. " Iris brown, feet reddish-brown, bill greenish-black, base red, in 

 young specimens yellowish." 



'^ Pambilar, 19. ix. 1900 (type!). Wing 1(13, metatarsus 31, middle toe 

 without claw 30, bill from forehead 2U mm. This is apparently a fully adult bird. 



S S. Javier, 15. vi. 1900. Wing and tail moulting. 



S S. Javier, 1. vii. lOOU. Young ! 



? S. Javier, 7. vii. 1900. Young I 



The young birds have the under-surfacc, which is slaty-grey in the adult ones, 

 washed with brown and buff, and the base of the bill is yellowish, not red. 



Unless the difference is se.xual it would seem that Venezuelan examples 

 of N. erijthropi (Merida) are smaller and darker below thaji Peruvian ones (Lima), 

 but we have at present no sufficient material for comparison. 



2. Automolus pallidigularis albidior subsp. nov. 



Automolus pallidigularis has originally been described from Panama. We 

 have three specimens from that locality, and I have compared six more in the 

 Britisli Museum, also five from Costa Rica in the Rothschild collection and three 

 in the British Museum. It seems that most of the specimens from Costa Rica are 

 slightly paler rufous on the back and under tail-coverts, but this difference appears 

 not to be constant enough for a subspecific separation. We may, therefore, for the 

 present, consider all the Central American forms to be the same — i.e. typical 

 pallidigularis. From all tBese our Ecuadorian specimens, six from S. Javier, 60 ft. 

 high, one from C^arondelet, also about 60 ft. high, in North- West Ecuador, collected 

 in May, June, July, and October, 1900, by Mr. G. Flemming, differ conspicuously 

 by their lighter, almost or quite white throat. The jugular feathers have also 

 more distinct whitish centres, and the breast and abdomen are slightly paler, less 

 brownish. The type is no. t>29 of the collectors, S. Javier, July 13th, 1900, 

 sexed " ? ." " The iris is brown, feet greenish grey, or light dirty greenish, upper 

 bill blackish brown, lower light yellowish." 



Wing, ? 90, c? 97, $ 96, i about 95 (July 2nd, slightly moulting) ; 

 ? ¥ (marked " cJ," but is most likely a ¥), 90 mm.
