Lastotchka daurskaya, RUSH. 



ad. (Siberia). Differs from H. rufula in having the black on the 

 head joined to the back, and not separated by the rufous collar, the lower 

 back and rump cinnamon-rufous with a few indistinct blackish lines, and 

 the under wing-coverts more rufous in tinge. Culmen 0'4, wing 5'0, tail 

 4*7, tarsus 0*55 inch. 



Hob. Siberia from the Irtisch to Dauria and the Ussuri 

 country, Mongolia, Kan-su and Ordos, China, Assam ; some- 

 what rare in Corea. 



In habits it does not differ from H. rufula, and like that 

 species builds a retort-shaped nest of mud lined with wool, 

 hair, or feathers, and deposits 4 to 6 white eggs. 



395. SUBSP. HIEUNDO STRIOLATA. 



Hirundo striolata, Temm. and Schlegel, Faun. Jap. Aves, p. 33 (1850) ;

<J ad. Differs from H. rufula in having the rufous collar interrupted on 

 the nape, the black on the head joining that on the mantle ; rump chestnut 

 with distinct black shafts ; lores black ; under parts coarsely streaked with 

 black, and the under tail-coverts with the terminal halves black. Culmen 

 0*4, wing 4*9, tail 4'0, tarsus 0'6 inch. 



Hal. Japan and China ; wintering in Burma, and as far south 

 as the island of Flores. 



In habits and nidification it does not differ from H. rufula, 

 indeed both the present form and Hirundo daurica can only be 

 looked on as subspecies, as specimens occur which intergrade, 

 though the extreme forms are readily separable.
