218 Viscount Walden on the Rufous-tailed Shrikes. 



we can arrive at a conclusion, the exact limits of the Philippine 

 bird's northern migration must be discovered, and individuals in 

 full breeding-plumage will have to be obtained. Schrenck's 

 species was obtained on the banks of the Schilka river, and also 

 on the coast of the Sea of Okhotsk. Middendorff procured it 

 only in the latter region, and states that it was the only species 

 of the genus obtained by him. The bird he identified as L. 

 excuhitor, Linn., but of which he failed in getting a specimen, 

 was probably L. bucejjhalus, T. & Sch. Radde, who, as well 

 as Middendorff, gives no description of his specimens, found L. 

 phoenicurus, Pall., not uncommon among the morasses along the 

 banks and at the mouths of the larger rivers which fall into Lake 

 Baikal. But the winter home of Schrenck's species has yet to 

 be discovered. Mr. Swinhoe did not observe the bird in any 

 of the parts of China visited by him. It would be of some as- 

 sistance if a description of the specimen killed in Heligoland 

 were to be published. 



The specific distinction between L. phoenicurus, Pall., and L. 

 collurio, Linn, (on the hypothesis that he possessed specimens of 

 Pallas's species), has been most conclusively demonstrated by 

 Schrenck (/. c). The specimen described by Sundevall (/. c), 

 preserved in the Stockholm Museum, must belong either to 

 Schrenck's species, or to Malay L. sujjerciliosus, Lath.
