Lhassa. The latter birds are now in the Paris Museum, and 

 Dr. Oustalet regards them as merely varieties of C. tibetanum^ 

 or hybrids between this species and the slate-grey C. aurilum, 

 Pallas, which has the greater part of the outer tail-feathers white. 

 We entirely agree with Mr. Seebohm in believing this con- 

 clusion to be a mistake, for C. auritum, we may further remark, 

 has the tail composed of twenty-four, not twenty feathers. 



It appears that the range of C. leucuruin overlaps that of C. 

 tibeta7ium in Eastern Tibet, and it may be that in this locality 

 the two forms interbreed, so it is just possible that Hodgson's 

 type of C. tibetanufn^ which has some white markings on the 

 six outer pairs of tail-feathers (see previous footnote, p. 252) 

 may be a cross-bred bird of this description, but the exact 

 locality where it was obtained is quite uncertain.
