Xearly adult male (Xo. "B," coll. Dr. G. Baur, Chatliaiu Island, 

 June 10). — Mucli like the fully adult male, as described above, but red 

 of pileuni paler afid mixed with many partly brown feathers, that of 

 under parts very much paler (deep salmon-cohu", very nmch paler on 

 chin and throat), and upper parts decidedly lighter warm grayish 

 brown. Wing, 2,28; tail, 2.05; exposed culmen, 0.30: tarsus, 0.65; 

 middle toe, 0.35. 



Adult female (No. 03, coll. Dr. Cx. Baur, Chatham Island, June 17). — 

 Forehead and broad superciliary stripe, extending from nostrils to 

 occiput, ochraceous-bufif; rest of pileum nearly same coh)r, but broadly 

 streaked with deep hair-brown, these streaks so broad on hind part of 

 crown as to nearly co'nceal the buffy edgings. Ear-coverts, hind neck, 

 back, scapulars, and lesser wing-coverts uniform hair-brown, the 

 rump, upper tail-coverts, and broad tips of greater and middle wing- 

 coverts paler and tinged with buffy; secondaries edged for terminal 

 half with pale buft'y grayish, and broadly maigined at tips with buffy 

 grayish white. Malar region, chin, and throat })ale buff, deeper later- 

 ally; rest of uiuler parts deep buff, becoming rather clearer and 

 brighter posteriorly, and everywhere devoid of the least trace of 

 streaks. Length (skin), 4.25; wing, 2.21: tail, 1.88; exposed culmen, 

 0..")8; tarsus, 0.()5; middle toe, 0.32. 



Immature male (No, 123, coll. Dr. (\. Baur, Chatham Island, June 

 25), — Much like the adult female, as <lescribed above, but top of head 

 nearly uniform grayish brown, like back, though showing indistinctly 

 defined broad streaks of darker aiul lighter, with a few concealed 

 bright yellow spots on center of crown; anterior part of forehead and 

 superciliary stripe, however, deep butty, as in the female; buff of 

 under parts deeper and yellower. Length (skin), 4.25; wing, 2.30; 

 tail, 1.92; exposed culmen, 0.39; tarsus, 0.03; middle toe, 0.38. 



The adult male described is the brightest colored one in a series of 

 eight, the remainder being more or less paler scarlet beneath. This 

 conspicuous ditterence of intensity between the red of the pileum (which 

 is exactly as in other forms) and that of the lower parts is, next to the 

 small size, the most striking character of the present species. 



Two other females in Dr. Barn's collection differ from that described 

 in having an appieciable (though in case of one very faint) yellow tinge 

 to the posterior under parts. 



Another immature male, also in Dr, Baur's collection, is <[uite 

 decidedly yeUowish on the posterior h>wer jjarts, the under tail-cov- 

 erts and malar region being nearly maize-yellow. 



There can be little donbt, I think, that Gould's ryrocepJialus dHbins 

 was based on a female or immature male of this form, but the (juestion 

 can be determined positively only by examination of the type, now in 

 the British ^Museum. The original description certainly fits the female 

 very well, and the measurements of the type, recently made for me by
