An adult male measures : — Wing 356 mm., culmen 50 mm. 

 height of bill at nostril 22 mm. 



Picus canus yunnanensis, subsp. nov. 



Like Picus c. jacobsi of Hupeh, but with more golden- 

 yellow on the upper parts and much larger. It differs from 

 P. c. ricketti in being of a much brighter green, in having 

 the coronal red of less extent, and in its much larger size. 

 It is widely removed by its bright colouring from P. c. sor- 

 didior Rippon, of W. Yunnan. 



Wing, J 156 mm., ? 150-5 mm. 



T^pes. c?, Milati (5000 ft.), S.E.Yunnan, 20 Jan., 1921. 



Four males and four females from Yunnan-fu and Kopao 

 tsun, COOO ft., are of much the same proportion, but are in 

 worn plumage with very tawny undorparts. Wing, J" 154, 

 154, 155, 159 mm., ? J 53, 154, 155, 159 mm. 



DryolDates pygmseus permixtus, subsp. nov. 



Nearest to7^ p. ohscurvs from the S.E. Yunnan-Tongldng 

 border, but larger and with as much white on the back and 

 wings as D. p. kaleensis of Fohkien. From the latter it 

 differs in its very dusky underparts and very heavy striping.

? , Kopaotsun (6000 ft.), 31 May, 1921. 

 I find it quite impossible to unite this bird with D. p. 

 kaleensis or D. p. ohscurus. We have, therefore, in iS.E. 

 Yunnan, three closely allied pygniy Woodpeckers, each of 

 them inhabiting a different district : — 



Dryobates p. ohscurus. Very dark and small. Hokovv 



(Tongking Frontier). 

 „ Imleensis. Milati (5000 ft.) (Mengtz 



vicinity). 

 „ permiMus. Kopaotsun and Yunnan-fu 



(6000 ft.), in winter down 

 to Milati.
