414 DR. F. H. H. GUILLEMARD ON BIRDS COLLECTED [Apr. 21, 



Both the young birds have the throat white, and the forehead 

 washed with chestnut. The white on the shoulder appears to become 

 cobalt by gradual assumption of that colour in the feather, and not 

 by moult.

In none of these is there any note of the sex. The three adult birds 

 are alike, except that in one the black nuchal collar is edged 

 posteriorly with shining dark blue, thus forming a second collar of 

 that colour. In the young bird the chin and upper throat are whiter, 

 and the rest of the under surface rufescent, darker on the breast, 

 and with some dark-blue feathers in the median line and on the 

 flanks. Above, the head and nape are light brown, and the 

 uropygium dark grey. The feathers of the back and scapulars are 

 umber-brown, with the base dark grey. A few red feathers of the 

 new moult are seen appearing irregularly here and there, especially in 

 the scapular region. 



The fifth example differs greatly from the others. On the upper 

 surface the head is rufous, merging gradually on the back into 

 the same shade of red as is seen in the adult male. Beneath, the 

 throat is whitish, and the rest of the under surface a uniform huffish 

 tint, the feathers black at the base. Bill brown ; lores and sides of 

 face fawn-colour. 



The above individual has no appearance of immaturity, and I 

 believe it to be the female. No allusion to any sexual differences of 

 plumage is, however, made by Schlegel (Mus. Pays-Bas), Salvadori 

 (Ucc. di Born.), or Elliot (Monog. Pittidse).

The last example differs from the others in having the under 

 surface buff, not yellow, but barred with bluish-black as in the adult 

 male. The blue abdomen is replaced by greyish feathers tinged with 

 rufous, which have lavender reflections in certain lights. Sinciput 

 and vertex brown, with three or four longitudinal black stripes ; 

 supraocular stripe fawn-coloured in its anterior, yellow in its 

 posterior half; subocular and auricular feathers black, tipped with 

 fawn ; occiput black. The bird is apparently mature.

This example corresponds in every way with those obtained at Meim- 

 bun during the visit of the ' Marchesa ' to Sulu Island. It is slightly 

 paler than Celebes skins ; the lores are brownish white, and the ex- 

 ternal rectrices have no white on the outer web as in G. sulplmrea.
