are whoUy black. In this respect it differs not only from 

 »leucoptera» but also from »bactriana» which by Hartbrt are 

 regarded to be identical. It is possible that the variation is 

 so great that intervening links may be found between spe- 

 cimens such as the two mentioned above and this one. Their 

 occurrence in the same locahty speaks for such a possibility, 

 but on the other hand the great size etc. is quite remarkable. 

 Hartert uses the name »bactriana» given by Bonaparte 

 (Conspect. Av. I) who says about the bird for which he in- 

 troduces this name, that it is »minus nitens» than the euro- 

 pean Magpie. This name cannot therefore be referred to a 

 Magpie Hke the specimen just described. 



75. Pyrrhocorax pyrrhocorax (L.). 



d" 19/4 1902 Chantengri; cT ''/g 1902 Baimgol. 



Wing 285—290, tail 165—170, tarsus 48, culmen 46—51 

 mm. 



These specimens appear to be of medium size to judge 

 from the measurements above, compared with Hartert's 

 statements (1. c. p. 36). 



76. Sturnus vulgraris porphyronotus (?) Sharpe. 



d" 174 Baimgol. 



Wing 128, tail 65, culmen 30, tarsus 30 mm. 



This specimen is very interesting in a certain respect, 

 because, although it shows the normal measurement of the 

 subspecies and with regard to its colouration on the whole 

 agrees with the typical porphyronotus, certain differences 

 make themselves very apparent. The whole head and neck 

 are glossy green, the back is reddish as in the latter, but the 

 light tips to the feathers are entirely wanting which is a 

 rather striking feature. A second discrepancy shews itself 

 in the colouration of the lower parts. These are not purple 

 as in porphyronotus, but have a bronzy gloss which only on 

 the chest just below the green of the foreneck has a narrow 

 transverse zone of purple, otherwise there is more green than 

 purple in the bronzy gloss of the under parts and the sides. 

 The tips of the under tail-coverts are margined with white 

 The scapulars are like the back, but the wings have the 

 same bronzy gloss as the under parts. Under wing-coverts
