on new Species of Central-Asian Birds. 41 1 



The same year, as we were skirting the eastern shore of 

 Koko-nor lake, on the 1/13 July, we came upon a hrood of 

 three young birds, again in drift-sands among clumps of 

 thick spruce-woods. The old birds were then moulting, and 

 their young had already abandoned the nest. The note of 

 old and young alike was very loud. . A short time afterwards 

 we came across a second brood in the mountains bordering 

 the plateau of Koko-nor lake. 



In the spring of 1884, on my fourth journey in Central 

 Asia, the first migratory specimens (three in number) were 

 observed on the 14/26 April on the southern slope of the 

 South Koko-nor range. They kept in the underwood, and 

 the males sang splendidly. A few days afterwards we secured 

 a solitary female, and lastly, during the autumnal flight in 

 the same year (1884), a single specimen was observed on the 

 15/27 August, in thickets of tamarisk in the ravine of the 

 Khatu-gol, on the northern margin of the Burkhan-Buddha 

 range. 



Thus L. giganteus is in general a rare bird, and up to the 

 present time only found in the basins of the Upper Hoang-ho 

 and Koko-nor lake. Like the Shrikes, its habits are preda- 

 tory. My companion, M. Roborowsky, once shot a female 

 which had just caught and devoured an Arvicola.
