north-eastern race (even extending över North America), 

 but botli breed at Irkutsk according to Taczanowski and 

 in Northern Mongoha as well as this collection proves. 



Hirundo urbica Linnaeus. 



Kjachta ef (n:o 112) ^3/5 19O8. 



This is a rather remarkable specimen. The tail is de- 

 cidedly less forked than in a typical male of Hirundo urbicay 

 but more deeply forked than in Hirundo cashmiriensis . 

 Lower parts all över as well as rump rather strongly washed 

 with smoky brown, even tlie feathers of the toes. Length 

 of wing 111 and of tail 57 mm. 



This swallow is thus in some respects intermediate 

 between the two species mentioned above. 



Taczanowski has not recorded Hirundo urbica (only 

 lagopoda) from Eastern Siberia and in Cat. Birds Brit. Mus. 

 Vol. X p. 89 it is said that it »straggles also to Turkestan 

 and North-western India.» The occurence so far east of a 

 swallow of this kind appears thus very remarkable. Mr. 

 Bamberg obtained two more specimens of the same size 

 one even 3 mm longer, he informs me, but they were löst 

 during the preparation. If the characteristics mentioned 

 above prove to be constant, as I believe they will, there is 

 evidently a subspecies of the common Martin which in some 

 respects forms a connecting link between the typical H. urbica 

 and cashmiriensis.

These specimens have been carefully compared with 

 a number of Swedish specimens of Dendrocopus tnajor and 

 I have found no conspicuous difference except with regard 

 to the bill. This organ is a little longer in these specimens 

 and at the same time more evently attenuated and pointed
