312 TIM ALII DJE. 



Distribution. Sikkim to Assam North and East of the Brahma- 

 putra, Abor and Miri Hills. The eastern limits are not yet 

 known, but Harington obtained it in the Kaehin Hills. 



Nidification. Similar to that of the previous two birds. Eound 

 about Margherita we found its nests on banks and sides of 

 cuttings through the jungle, made of soft tow-like material mixed 

 with moss, leaves and rubbish, more or less filling the base of the 

 hole in which it was placed. The eggs were generally three only, 

 rarely four and they differed from those of the Chestnut-headed 

 Staphidia only in being a little more richly marked. One hundred 

 eggs measured on an average 1 6-6x13-3 mm. and the extremes 

 were 180xl3'2 mm., 16-2 x 13*7 mm. and 14'7xl2'4 mm. 



The breeding season lasts from March to June. 



Habits. This little Staphidia is found in parties throughout 

 the cold weather, according to Stevens sometimes numbering as 

 many as thirty individuals. It haunts trees and brushwood alike 

 both in forest and in the secondary growth and has the usual 

 restless habits of its tribe. It is not a shy bird. It probably 

 ascends as high as 4,000 feet in summer but is more a low-level 

 bird, keeping for the most part from the foot-hills up to about 

 2,000 feet. 



Genus SIVA Hodgson, 1838. 



The genus Siva contains two species which occur within our limits, 

 these being divided into several well differentiated geographical 

 races. They are distinguishable at a glance from other genera by 

 their peculiar tail-feathers, the ends of which are obliquely truncated. 

 The four central pairs are of equal length and the two outer pairs 

 graduated. 



The bill is about half the length of the head, gently curved and 

 notched ; the rictal bristles are long and the nostrils are covered 

 by a membrane ; the head is crested and they are birds of hand- 

 some plumage.
