Mr. B. C. Stuart Baker described two new races o£ 

 Flycatcher, and made the following remarks : — 



Hemichelidon sihirica Grinelin has hitherto been divided 

 into two i*aces : 



(1) Hemichelidon sibirica sibirica Ginelin, S. N. i. 

 p. 936 (1788 : Lake Baikal). 



Tbis is a very grey bird, with more and purer white below 

 than in any other form. Wing 75-8.3 mm. 



Habitat. East Siberia, from Kamschatka to Lake Baikal 

 and Manchuria ; in winter south to South China, but 

 apparently not to the Indo-Chinese countries, Borneo, etc. 



(2) Hemichelidon sibirica caccabata Penard, Proc. 

 N.E. Zool. Club, vii. p. 21 (1919 : Nepal). 



This is the H. fuUginosa of Hodgson — a name which 

 cannot be used, as Penard has shown it to be preoccupied 

 twice over. 



It is a much darker bird, more brown and less grey, and 

 with the white below less in extent and more smoky. Wing 

 70-75 mm., in one instance 76. 



Habitat. Nepal, Sikkim, Assam, Burmese Hills, Chin, 

 Kachin, and Shan States, Siam, Malay Peninsula, Borneo, 

 etc. 



There appear, however, to be two other well-marked 

 races : 



(3) HemichelicLoii sibirica gulmergi, subsp. nov. 



Tyjje. In the British Museum. No. 94.8.13.13. ?, 

 Gulnierg, Kashmir. 1st July, 1893. Dr. Aitchison. 



This form is intermediate between the two last, darker 

 and more brown than in H. s. sibirica, lighter and more 

 orey than in H. s. caccabata, with which it agrees in size. 

 Wing 70-76 mm. 



Habitat. N.W. India, Chitral, and Gilgit to Garwhal.
