Above (lark olivc-liruwii, more olive on tlif iiitersciX])uliiiin, back, aud rump, 

 more brown on the wings and tail, and lighter on the head, especially on the 

 forehead. Underside and sides of the head brownish olive, much paler ou the 

 abdomen and nearly whitish ou the lowest abdomen. (!hiu very pale, almost 

 whitish ; some feathers at the angle of the mouth and just below the chin with 

 blackish tips. A broad hlack stripe running from the lores over the eye towards 

 the na]ie. A triangular spot behind the eye bare. Under tail-coverts olive-brown 

 with whitish shaft-strijies. Under wing-coverts greyish olive. Bill orange. Feet 

 orange-yellow (in skin). 



Several specimens from Bonthain Peak, (iOOo feet and above. 



Altogether of a much Thrush-like appearance. The tail is nearly square, 

 the outer tail-feathers only about 9 mm. shorter than the central pair. The 

 feathers of the forehead reach in two angles towards the nostrils, which are large, 

 oblong, and but partly covered by a membrane. The gape an'/ th- feathers of the 

 chin have short bristles. 



The generic name is given in reference to the difficulty and hardships con- 

 nected with the shooting of these birds in the great altitudes tliey inhabit. 



4. Siphia omissa sp. no v. 



The tiiphia from Celebes has hitherto been considered the same as Siphia ban- 

 i/iaiias (Horsf.), but Messrs. A. B. Meyer & Wiglesworth have already noticed that 

 a female they got from Messrs. Sarasin has " hell rOthlichbrauneu Ziigelstreif." * 

 This is indeed the most striking specific difference, i.e. that the adult female has the 

 lores pale orange rufous and that this colour meets on the forehead, while the adult 

 female of <S. hainjumax has two wlnte spots ou the lores, sometimes tinged with 

 yellowish, which are widely separated from each other on the forehead. Besides 

 this the ear-coverts are of a very deep bine, almost blackish, in 8. bani/umas, while 

 they are brown with pale shafts and tinged with pale bluish posteriorly in 

 iS'. oinissa. The ///ale.s of the two sjiecies are very much alike, but the upper ])art 

 of the throat, just below the black chiu, is not perce])tibly paler than the rest of the 

 throat in S. omissa, while there is a distinct though tiny white sjwt in /S'. haivjumas 

 and the whole throat is darker in S. omissa. Besides this the brighter blue colour 

 of the forehead and line above the eye is much lighter and more distinct in 

 .S'. omissa, where it may be said to be of a dark azure-blue. The upper surface too 

 oii\i& female is a little paler than in the female of iS. hanijmnas, while there is very 

 little difference in the colour of the ti])])erside in the males. Of S. omissa I have 

 before me a series of both se.xes and young from the hills of Indrulaman, about 

 '^500 feet high, jnst below Bonthain Peak (types), and a pair from the lake of 

 Tondauo, collected for Dr. A. P>. Meyer in 18!)~'. AVing : ? 72 — 73, S 75 — 78 mm.
