106 NOVELTIES. 



small as the differences are, they appear to be constant between, 

 the birds of the Himalayas and the Central Tenasserim Hills, 

 and such being the case, we must, I presume, accept the present 

 form as a distinct species. 



The difference in the size of the bill though difficult to ex- 

 press in figures, and the bright orange buff forehead and entire 

 lores are very conspicuous and caught my eye the moment I 

 saw the Tenasserim bird. 



The following are the dimensions of a male of the present 

 species or sub-species, taken from the dry skin : — Length, 5*2 ; 

 wings, 2*45 ; tail, 2; tarsus, 087; bill from forehead, 0'6; 

 from gape, 0*61. The bill black, yellowish on lower mandible. 

 Legs and feet very pale, probably in life fleshy white. 



A moderately broad frontal band, the whole of the lores, a 

 stripe over the eye and a circle of feathers round the eye (this 

 latter also is wanting in moniliger) rather pale orange buff. 

 The entire upper surface a rich, somewhat rufescent olive, (some- 

 what lighter and more rufescent than in moniliger), becoming 

 ferruginous on the upper tail-coverts. The tail is deep ferru- 

 ginous, brighter colored and more rusty on the margins of 

 the* feathers. Wings hair brown, margins and visible portions 

 of closed wing overlaid with a somewhat rufescent olivaceous 

 tint. A satiny white patch commencing at the point of the chin 

 and descending well on to the breast, (1*35 in length), something 

 the shape of an inverted hare bell ; a very narrow, scarcely 

 noticeable brown line bounds this patch on either side, and a 

 narrow dark line below. The rest of the breast, sides and 

 flanks, sides of the neck ; cheeks and ear-coverts, olive, only 

 slightly paler than the upper surface, but the cheeks and ear- 

 coverts, much more rufescent and with a tinge of the colour of 

 the lores. Middle of abdomen, vent and lower tail coverts dull 

 white. Shoulder of the wing pale fulvous ; axillaries silky white. 

 I thought at first that this would prove identical with A. 

 gularis, Blyth, from Arrakan, but I find that Arrakan speci- 

 mens appear almost identical with Himalayan ones ; want the 

 bright rufo-fulvous forehead, lores and eye streak and have the 

 black gorget border fairly developed. 



Ixulus humilis. 



Entire upper parts, cheeks and ear-coverts brown, entire lower parts 

 white, striated longitudinally with brown. 



Male. — Killed, Moolyit, Central Tenasserim Hills, 16th Febru- 

 ary 1877 : — Length, 5*2 ; expanse, 7*8 ; tail, T8; tarsus, 0'8 ; 

 wing, 25 ; bill from gape, 0*6 ; weight, 0*62 oz.
