and in his »Catalogue of the known species of Alaudidae >. ^ 

 he has left it out entirely. It may nevertheless, be possible 

 that in some places local races of smaller size exist, and 

 such a view is corroborated by the fact that the length of 

 wing of the male specimens in this collection are resp. 101, 

 103, 106, and 107 mm and that of the female 95 mm. This 

 species as well as the other Larks were found by Mr. Bamberg 

 »on the steppes and on the mountains as well at a height of 

 2000 m. as of 600 m. On approaching them they did not 

 fly at once but tried to run away among the grass or över 

 the sand quite quickly. If they could not gain enough by 

 this they tried to come away a little faster by flying but not 

 very far.»

The first of these is evidently a specimen of the large 

 typical race: Wing 96, tail 76, culmen 19, tarsus 32, hindclaw 

 21 mm. The second is a little smaller: Wing 94, tarsus 30, 

 hindclaw 19,5 mm, but the measurements and other charac- 

 teristics prove it to belong to the same race, as well. The 

 third has the same length of wing and tarsus as the second 

 but the hindclaw is only 18,5 mm it is however longer than 

 the toe by 2,5 mm. It is of interest to state that the typical 

 form breeds in Mongolia. 



Anthus trivialis maculatus (Jerdon).

The time of the year at which these specimens have 

 been collected prove that this Pipit breeds in Mongolia as 

 well. 



Motacilla alba baicalensis (Swinhoe).

These specimens are quite typical but a male from 

 Kiran is perhaps more correctly termed:
