34 Ornithological Ohervations in the Sullej valley, [No. 1 



feathers on the top of the head being centrally streaked pale brown; 



backup and scapulars blackish ashy, the feathers somewhat more ashy 



near the tips which are black ; wings dusky brown, wrth a rufous t.nge 



on the outerwebs ; most of the longer wing coverts are centrally tipped 



pale brown ; tail dusky brown, obsoletely barred on the outer webs, 



outermost pair is paler than the rest ; sides of neck olive brown the 



Ihers with pale brown spots and blackish tips a short black s reak 



extends down from the base of the lower mandible ; clun and throa 



Iwish white, each feather tipped dusky ; the feathers on the breas^ 



are olivaeeons brown with black tips, some of them on the sides w.th 



pale spots ; centre of the abdomen and vent white, the feathers tipped 



black; sides of vent rather uniform dusky, lower tadcoverts ashy, 



tipped with white. 



97 PKTEOcossvrnus ounu* L i «, (L 511), very common, ex- 

 tending all through the N.W. Himalayas, from the plains _ into W, 

 Tibet- it also proceeds further to Central Asia and Siberia. The 

 specimens from the lower hills occasionally have in summer some 

 ferruginous colouring on the sides and the lower tail coverts but those 

 of W Tibet have not a trace of it. They appear to be a little smaller 

 than the European birds, hut there is no real specific distinction 

 between them. A specimen, shot in winter at Kotegurh, is entirely 

 blue, with dusky wings and tail ; it also has nowhere a trace of white 

 or ferruginous. The plumage of the young bird, which in general 

 resembles the female, exhibits variations quite similar to those known 

 in the European species. _ 



Of the second species of this genus Pteroc. castaneocolhs* Less. 

 (I 519) I obtained in the beginning of September 1865 a fine 

 specimen north of Dras, in W. Tibet. It ought to occur in the 

 Punjab during the winter. The colouring quite agrees w.th the 

 description quoted by Dr. J e r d o n. _ 



98 Orocestes eeythrogastra, Vig., (I. 514) is only found in th< 

 lower hills about Simla and Kotegurh ; but the next smaller species, 

 99. Orocestes cinulorhynchcs, Vig., (I. 515) goes further tc 



* T hive since, in the Vienna Museum compared this with a young, male of 

 ♦hi EaropeS X. smatiUs, with which it perfectly agrees. The two speoes 

 thereto^ very probably are identical, (Feb, 1868).
