the females from Hnmaytha in general coloration, but tlie pileuui and crest are even 

 browner than in the younger bird, the belly is much darker, deep sepia brown with 

 a slight rufescent tinge, and the black bars on the interscapulium and upper wing- 

 coverts are broader. Whether these differences are of any importance cannot 

 be decided until more specimens of both sexes from Ecuador come to hand.

 Atioplqpa hoffmaimsi Hellmayr, Bull. lint. Orn. CI. xix. (Fub. 1907), p. 52 (Borba, Rio Madeira). 



No. 1417. S ad., Borba, 29. xi. 06. " Iris brown, feet and bill black ; naked 

 ring round the eye light yellowish green." — Wing 81J; tail 54; tars. 27 ; bill 

 18i mm. Type of the species. 



No. 1431. ? ad., Borba, 2. xii. 06. " Iris light yellow, feet bluish black, bill 

 black, below grey ; naked ring round the eye light yellowish green." — Wing SI ; 

 tail 53; tars. 26 i ; bill 17J mm. 



Feathers of the forehead and lores rather stiff and erect, those of the pileum 

 much lengthened, narrow, decurved, and forming a distinct, loose crest. A broad 

 naked space round the eye pale yellow in the skins. Tail rounded, the outermost 

 rectrix being about 4 to 6 mm. shorter thau the longest. 



<? ad. Forehead, lores and occiput deep black ; feathers of the crest black, dull 

 chestnut at the concealed base. Back, lesser and median upper wing-coverts pale 

 dull olive ; upper tail-coverts and greater wing-coverts rufescent olive-brown. 

 Quills dusky, bright russet on the outer webs ; innermost secondaries rufescent 

 olive-brown. Tail-feathers dark brown, slightly more rufescent along the outer 

 webs Cheeks, malar region, throat and foreneck pure white ; rest of the under- 

 surface dull slaty, abdomen and sides of the breast washed with olive brownish. 

 Under tail-coverts pale olive-brown, with a narrow whitish apical margin. 

 Axillaries and under wing-coverts sooty-brown ; inner webs of the remiges broadly 

 edged with clear cinnamon. Bill and feet black. 



¥ ad. Differs in having the forehead and crest dark chestnut, the shaft of the 

 feathers alone being blackish. The back is bright olive-brown, the wings and tail 

 much more rufescent brown than in the male. The feathers of the upper back as 

 well as the wing-coverts are crossed by a broad black snbterminal bar followed by 

 a narrow cinnamomeous apical margin. Cheeks, malar region, throat and foreneck 

 white, as in the male. Chest and middle of the breast ochreous, broadly banded 

 with black (two black bars on each feather) ; sides of the breast and abdomen 

 uniform warm olive-brown ; under tail-coverts light olive-brown, with several 

 alternative blackish and ochreous cross-bands. Axillaries light olive-brown ; under 

 wing-coverts tawny, irregularly barred with blackish. The three innermost 

 secondaries show a distinct black subterminal bar and an obsolete buff apical 

 margio. Bill black, lower mandible whitish. 



This remarkable new bird, although aberrant in coloration, is certainly 

 congeneric with .1. rufi.gu.la (Bodd.), tin- form of wing and tail as well as the shape 

 of the nostrils (a narrow, longitudinal, slit-like opening, overhung by abroad, rather 

 thickened membrane) being perfectly similar in the two species. It differs, however, 

 by the rather stiffened, erect frontal feathers and tin' distinct crest, in which respecl
