Chosen, Gerchneis perpaTlida^ and it may eventually prove to be the 

 proper name to use for the present form, if recognizable. The type 

 has a lighter gray head and a grayish bloom to the back not seen in 

 the series of males from Ninghsia, Kansu; it is much lighter below. 

 The form was founded on the single specimen, which may be aber- 

 rant or it may represent a recognizable form with a more eastern 

 distribution than C. t. dorriesi. For the present I prefer to adopt 

 a name of certain application.

23. PERDIX BARBATA BARBATA Verreanx and Des Mars 



Perdix barbata Vekeeaux and Des Mues, Proc. Zool. Soc. London, 1863, p. 62, 

 pi. 9 (Nertschinsk, Dauria). 



One female, 107 miles west-northwest of Paotow, Inner Mongolia, 

 April 4 ; one male, 45 miles northwest of Ninghsia, Kansu, May 3. 



These two specimens are paler, above and below, than any in a 

 small series from north China; in fact they are even paler below 

 than a male of Perdix h. turcomana from Gulera, Ferghana, 

 U.S.N.M. No. 159722. The chestnut bars above are somewhat 

 heavier, especially in the female, than in North China specimens.
