166. Antiius cbbvinus, Pall., (II. 237), 



167. Hetekuba sylvaxa, Hodgs., (239) also occur during "the 

 glimmer months in the Stitlej valley, but they are generally confined to 

 the lower western portions of it, and do not usually migrate further east- 

 wards than Nachar. The elevations upon which they are found lie 

 between 2,000 and 6,000 feet. In eases of the absence of grassy and 

 shrubby slopes they are very seldom met with in the denser pine for- 

 ests. The Agrad. sordida breeds at Kotegurh, and the Hei. sylvana is 

 occasionally seen near Oiiini, where it also breeds. It is the only 

 species which is more common in the valley, and Bometim.es even 

 remains during the winter in the neighbourhood of Kotegurh and 

 Simla. All the other species migrate at the beginning of the cold 

 weather to the plains of Northern India, or to the Dhoons of the Sub- 

 Ilimahiyan hills.

It almost appears to be a very unnatural separation to remove from 

 each other the genera Ptheruthius andLanms, under the last of which 

 P. erythvoptevus has originally been described. The species seems 

 to combine the characters of Lanius and Tephrodornis, possessing the 

 shape of the bill of the former and the short tail of the latter. 



Male ; some of the ashy feathers on the back are often tipped black ; 

 the primaries and secondaries and their coverts are shining black 

 on the outer, dull black on the inner- webs ; the quills, beginning 

 at the third primary, are tipped white on the inner webs, the white 

 increasing up to the sixth primary, then again decreasing, until 

 it disappears on the last secondary ; a white wing patch is formed 

 by the basal half of the inner webs of all the secondaries and of the 

 primaries, with the exception of the first primary. Below white, all the 

 feathers dark slaty at their bases, abdomen of a light fleshy colour, 

 under tail coverts pure white. The tips of the tail feathers are 

 distinctly mucronate, and have sometimes traces of golden yellow. 



The female has the tertiaries somewhat duller ckesnnt ; only the 

 two central tail feathers are wholly dingy green, the others mostly 

 black, greenish on the outer webs and tipped yellow, which increases 

 towards the outermost pair,
