(89) Z. simpLEx.—Swinhoe’s White-eye. 
Oates, No. 228 ; Hume, No. 681 B- 
The common form to the south and south-east. The numerous 
nests and eggs I have taken differ in no way from those of Z. palebrosa, 
nor does its habits call for any remark. 
(90) Ixunvs ocorprtaLis.—The Chestnut-headed Ixulus. 
Oates, No. 231 ; Hume, No. 624. 
Very rare. I have seen only two specimens. 
(91) I. Fiavicoti1s.—The Yellow-naped Ixulus. 
Oates, No. 232 ; Hume, No. 623. 
All my nests, with two doubtful exceptions, have been taken from 
the ground. The eggs are, as Oates says, just like rather densely- 
marked eggs of Hirundo rustica, but I think they are more brightly 
marked on the whole. 
(92) HuRPoRNIs XANTHOLEUCA.—The White-bellied Herpornis. 
A yery rare bird in North Cachar. I have only seen it about 
half a dozen times, and on these occasions it was always in small flocks, 
and engaged in the busy pursuit of insects on the higher branches 
of lofty trees. I have only observed it on the outskirts of tree-forest. 
I do not remember ever hearing their notes, and they seem very silent 
birds. 
Sub-family Liotrichine. 
(93) Liorarix LutEA.—The Red-billed Liothrix. 
Oates, No. 235 ; Hume, No. 614. 
Fairly common on some of the higher peaks. 
(94) CuTta NEPALENSIS.—The Nepal Cutia. 
Oates, No. 236 ; Hume, No. 612. 
I have seen this bird during the cold weather, on two or three occa- 
sions, towards the north-west of the district, haunting the tops of the 
oak trees which are the principal timber in that part. The elevation 
of the highest peaks in this direction is under three thousand feet. 
(95) PETRUTHIUS ERYTHOPTERUS.—The Red-winged Shrike-Tit. 
Oates, No. 237 ; Hume, No. 609. 
Not uncommon at about 8,500 feet upwards, but seldom appears to 
come down below this height. These birds are very shrike-like in all
