Lanius schach Linn., S. N., ed. x, p. 94 (1758). Type-locality: China.
Keg to Subspecies.
A. Upper back more or less suffused with
rufous L.s. erythronotus, p. 295.
B. Upper back with no tinge of rufous L.s. caniceps, p. 296.
I retain Lanius tephronotus as a species. It has no white wing-speculum and has the tail always brown, not black. These two features are constantly present throughout all the races of schach from Europe to Formosa, and the absence of them in tephronotus seems to me of sufficient importance to warrant its specific separation.
