* The description given by Pallas from Steller's notes suits this species in 

 some respects, but is so very incorrect in otlier points that Taczanowski con- 

 siders it impossible to say to what species it refers (Bull. Soc. Zool. Fr. 1876, 

 p. 262). Nordmann's name is unquestionable as regards adaptation, and has 

 been long, as well as generally, accepted.
