14. Criniger ruficrissus, sp. n.
C. similis C. gutturali, sed supra ubique sordidior, supracaudalibus caudaque saturate rufescenti-brunneis; loris et regione oculari cum genis et regione parotica sordide cinereis, gula alba, corpore reliquo subtus sordide olivascente, sub caudalibus castaneis. Long. tot. 8, culm. 0·85, alæ 4·0, caudæ 4·0, tarsi 0·7.
This species is not very different from C. gutturalis, but differs in its much darker coloration, especially on its under surface, which is dull olivaceous, with a white throat and chestnut-red under tail-coverts. There is an entire absence of the pale-brown colour of the breast washed with yellow, and of the light yellow abdomen and pale fawn-coloured under tail-coverts. The crest is very long in C. ruficrissus, and extends nearly to the mantle.
15. Ianthocincla treacheri, sp. n.
I. similis I. mitratæ (S. Müll.), ex Sumatra, sed genis, mento et regione parotica sicut caput castaneis facile distinguenda. Long. tota 10, culminis 0·85, alæ 4·15, caudæ 4·5, tarsi 1·5.
Adult. General colour above dark ashy grey, with a very slight shade of ochraceous under certain lights; the wing-coverts slightly more bluish grey than the back: quills blackish, externally bluish grey, the primaries white along the basal part of the outer web, giving the wing a conspicuous white outer aspect; tail-feathers dark slaty grey, shading into blackish at the end of the feathers; entire crown and nape, as well as the sides of face, ear-coverts, and fore part of cheeks deep chestnut-red, the under cheek-feathers slightly tipped with ochraceous; frontal plumes with lanceolate tips of light ashy grey or hoary whitish; under surface of body dull ochraceous brown, with lighter shaft-lines of pale ochraceous, imparting a striped appearance to the throat and breast; the sides of the body more ashy grey; chin chestnut, like the sides of the face; thighs dark grey, with a few chestnut feathers near the tarsal bend; under tail-coverts chestnut; under wing-coverts ashy grey, slightly marked with ochraceous; quills sepia-brown below, paler along the edge of the inner web.
Four specimens are sent by Mr. Treacher, all adult, and exactly similar in plumage. On comparing them with Sumatran specimens of I. mitrata, a very marked difference presents itself, which shows that the Kina Balu bird belongs to a new species. Although similar to I. mitrata in its general coloration and white-edged quills, it is distinguished at once by its chestnut ear-coverts, while the chin and fore part of the cheeks are also chestnut.
