LÖNNBERG, A CCLLECTION OF BIRDS FROM TIANSHAN. 21 



wing-coverts are not at all (or verv little and exceptionally) 

 white-tipped. The sixth or seventh and some of the in pro- 

 ximal direction following quills have a small pointed white 

 tip 1 — 2 mm. This is a discrepancy from Hartert's diag- 



nose ^ in which he says » die Schwingen haben keine 



weisse Spitzen», but otherwise these specimens agree with his 

 N. c. rothschildi. The size agrees also with this form, being 

 larger than in the swedish specimens. The white tips of the 

 outer tailfeathers are about 2^2 cm. thus rather less than in 

 other asiatic forms. 



73. Pica pica (L.) 



d" 15 4, 9 i'75 Baimgol. 



Wing 195—205, tail 245—260, culmen 37 mm. 



I cannot find that these two specimens differ from swe- 

 dish Magpies except therein that they perhaps are a little 

 larger than the average. They are both old birds with very 

 glossy plumage and somewhat worn tailfeathers. They have 

 310 traces of white on the feathers of the throat as P. p. 

 hactriana is said to have in most cases. (Conf. Hartert 1. c. 

 p. 21). 



74. Pica pica leucoptera Gould. 



d ^/ö 1902. Baimgol. 



Wing 230, tail 290, culmen 40 mm. 



This bird differs rather strikingly as well in size as in 

 colouration from scandinavian Magpies and also from the two 

 above recorded specimens. The metallic gloss is very strong 

 so that the wings appear to be quite blue with only little 

 greenish tint, the tail again quite green with the coppery and 

 purple band w^ell developed on the lateral feathers. The 

 white on the quills is strongly developed so that it shows 

 even w^hen the wing is folded together. On the first and 

 second primary- it reaches the tip of the inner web, on the 

 third it ceases 2 mm. from the tip on the fourth 3 mm., on 

 the fifth 4 mm., on the sixth 4^2 mm., on the seventh 7 mm. 

 etc. The name leucoptera seems therefore to be very suitable. 

 The feathers of the throat have no white at their base, but
