LÖNNBERG, A COLLECTION OF BIRDS FROM TIANSHAN. 11 



accessible to me I could find but one »Baimgol» which 

 was situated in Mongolia not very far from the town Urga. 

 Since that I have learned that several rivers in Central Asia 

 have such a name and that the one meant in this special 

 case is a tributary to Tekes in the Tianshan district and that 

 the specimens of Black Grouse referred to above beJong to 

 the collection described in this paper. It was therefore an 

 unfortunate mistake when I named this subspecies »mon- 

 golicus», but this cannot now be altered. It may, however, 

 be observed that the type locality is Tianshan. 



L. t. moiigolicus differs from other geographical subspe- 

 cies of Black Grouse through its large size, the wing in the 

 male measuring 282 mm. in the females 244 — 247 mm. The 

 male has blue gloss and differs thus from L. t. viridanus. 

 Neither male nor female have any white at the base of the 

 tailfeathers through which they are easily distinguished from 

 L. t. tschusii. The female of the new subspecies is not so 

 ferrugineous in the colouration of the neck and chest as 

 the female of L. t. viridanus. The great development of the 

 white on the wing — quills, greater coverts and bas tärd wing 

 — indicate the eastern type so completely different from the 

 Scandinavian. For other details I refer to the paper quoted 

 above. 



31. Fulica atra L. 



cTcTcr 1-^/8, o" 17/8, cT i^/s 1902, and a young without date 

 on the label, all from Baimgol. 



Wing 211 — 217, in one specimen, however, only 200 mm. 

 although it was labeled as ef, but it may have been a mi- 

 stake about the sex. Middletoe and claw 90 mm. in a 9. 



The olive shade on the back and wings of these speci- 

 mens seems to be more pronounced than in swedish speci- 

 mens. Feet and tarsi look in the dry specimens quite black. 

 The measurements agree pretty well with the corresponding 

 ones in swedish specimens, but the colour differences men- 

 tioned might indicate that a comparison with greater mate- 

 rial shall prove an eastern geographic race. 



32. Otis dybowskli Tacz. 



cfcf 25^g^ § 19^ 1902 Baimgol. 



The female specimen is rather similar to a female of 

 Otis tärda, but a good deal lighter on the upper parts. The
