Nachuka, and Sungpan). From northeast Kansu and just over the 

 border in Inner Mongolia it has four males and two females, and 

 from the Eastern Tombs, Chihli, one female. 



The series from Szechwan is darker on the breast and belly and 

 considerably darker on the upper tail coverts when compared with 

 the Kansu and more northern specimens ; there seems to be no appre- 

 ciable difference in size. The single male from Sungpan is somewhat 

 intermediate; the upper tail coverts are slightly lighter than those 

 of the more southern birds, but darker than in the northern race ; I 

 would, however, place it with the southern form for the present. 



When the above race was described, I overlooked comparing it 

 with Goluniba taczanowskii Stejneger.® The latter was founded upon 

 a single adult male from southern Korea. This specimen is certainly 

 darker than the series from Inner Mongolia and northeastern Kansu, 

 which I regard as Goluniba ruyestris imfestris for the present, and 

 the chest is more extensively suffused with a darker vinaceous-purple. 

 Colmnba taczanowskii is certainly very close to Golumha t'upestris 

 austnna; it is only slightly lighter and has the chest a little more 

 extensively vinaceous-purple. If more material should make it ad- 

 visable to recognize an eastern race of Golumha rupestris^ it seems to 

 me the name Golumha leucosonura Swinhoe ^ described from Talien 

 Bay, southern Manchuria, will have to be used for it.

One female, Yangtze Gorge, Yungning, 10,200 feet, Yunnan, May ; 

 three males and one female, southwest Szechwan (between Bonti 

 and Waerhdje, 14,000 feet, July; Yulonghsi Valley, 13,000-16,000 

 feet, May ; Tatsienlu, 9,500-10,000 feet. May) . 



If Stuart Baker's description ^° of Guculus optatus holds good, then 

 the majority of the birds that were so identified previously from 

 Yunnan" and the above belong to hakeri. All the specimens in 

 the United States National Museum from the mountains of Yunnan 

 and Szechwan, except three young of the year from Yunnan, have 

 the carpo-metacarpal joint of the wing white, barred more or less 

 with grayish or dusky. The only available specimens having the 

 carpo-metacarpal joint white and unbarred are six from Japan (only 

 two adults), one from Copper Island, two from near Shanghai, tAvo
