from the base of the forehead to above the eye a half-concealed streak of silky white. Total length 5‘7 
inches, culmen 0*65, wing 2'45, tail 2, tarsus 1*15. 
Adult female. General colour above indigo or slaty blue, the scapulars like the back ; lower back 
mixed with reddish brown ; rump of the latter colour, deepening towards the upper tail-coverts, which 
are deep chestnut ; lesser wing-coverts like the back, with dull rufous margins ; median and greater 
coverts, bastard-wing, primary-coverts, and quills dusky blackish, edged with deep chestnut, especially 
distinct on the latter, which appear chestnut; tail-feathers deep chestnut-brown ; crown of head chestnut- 
brown, more dingy on the hind neck, which is slightly mixed with the blue of the back ; forehead, lores, 
eyebrow, sides of face, ear-coverts, cheeks, and under surface of body rich chestnut; sides of body, flanks, 
thighs, and under tail-coverts rather deeper in colour and more chestnut-brown ; under wing-coverts and 
axillaries deep chestnut; quills below dusky, more ashy along the inner edge. Total length 5*3 inches, 
culmen 0 - 6, wing 2*4, tail 1*9, tarsus 1*15. 
This species has a certain resemblance to the male of B. cruralis, but instead of having a distinct 
white eyebrow, it has only a half-concealed white mark on the sides of the crown. The female is of 
course quite different from the hen of any other species of the genus. 
A young male in Mr. Whitehead s collection is of a duller blue than the adult male, and not only 
has the abdomen washed with rnfous, but has some rufous feathers on the breast, evidently the remains 
of the first plumage, which must therefore resemble that of the adult female. 
[Frequents the true forest from 4000 to 8000 feet, though very scarce at the lower elevation, owing 
to the Dusun rat-traps, which have almost exterminated all the small mammals and ground-loving birds. 
This species, like the little Androphilus, was most difficult to shoot from its extreme tameness, as it often 
came within a few feet of us, and followed us for several yards through the forest, making it extremely 
hard to obtain specimens without blowing them to bits. Eye dark brown ; feet and bill black.] 
120. Orthnocichla whiteheadi, sp. n., Sharpe. 
Adult male. General colour above warm chocolate-brown ; wing-coverts like the back ; bastard-wing 
and primary-coverts blackish, externally edged with chocolate-brown ; quills blackish, the primaries 
externally lighter brown than the back, the secondaries like the latter ; tail-feathers blackish, narrowly 
margined with brown ; crown of head blackish brown, as far as the nape ; hind neck like the back ; a 
broad eyebrow of tawny buff running from the base of the nostrils to the sides of the hind neck ; sides of 
face tawny buff below the eye ; lores, feathers round eye, and ear-coverts blackish brown ; cheeks and 
under surface of body pure white ; the fore neck and breast mottled with a few ashy margins to the 
feathers; sides of body, flanks, and thighs ashy brown, more decidedly dark ashy on the sides of the 
breast; under tail-coverts lighter brown ; under wing-coverts and axillaries blackish, edged with white ; 
quills below blackish, more ashy along the inner edge. Total length 3*3 inches, culmen 065, wing 1*95, 
tail 0*8, tarsus 0*8. 
Adult female. Similar in colour to the male. Total length 3*3 inches, culmen 0'5, wing 1*85, 
tail 1*85, tarsus 075. 
This peculiar little bird seems to be strictly congeneric with my Orthnocichla subulata from Timor, 
and though so strikingly different in colour, there are several points of characteristic resemblance, viz. 
the white under surface, the pale yellowish-white legs, and the broad eyebrow. 
[Very Wren-like in habits, frequenting the undergrowth close to the ground, through which it 
creeps more after the manner of a mouse than of a bird. This little bird is apparently rare, and in my 
expeditions I only procured three specimens, which were met with in the true forest at elevations of from 
four to seven thousand feet. Eye black ; feet and claws white ; bill brown.] 
121. PoMATORHINUS BORNEENSIS, Cab. 
[I only met with this species in the old Dusun rice-clearings, at about 1500 feet, where it frequented 
the low growth near the ground, especially where broad coarse grasses were abundant. In these spots it
