(2) Picus canus gyldenstolpei. 



Stuart Baker, Bull. B. O. C. vol. xxxix. 1918, p. 19. 



Type local! tij. Sadiya, Assam. 



Type No. 87.8.10.1023. S ex Hume Coll. British 

 Museum. 



A medium-sized bird, Avitli a wing of an average of 

 142 mm. and varying between 130 and 149 mm. 



Distinguishable at a glance from every other subspecies 

 by the strong bronze-yellow sheen on the upper plumage, 

 especially on the wings. A bird from the area inhabited by 

 this form can be picked out without hesitation from any 

 number of allied skins. 



Habitat. Sikkim, Bhutan, the whole of Assam, north and 

 south of the Brahmapootra to the extreme east, and running 

 south through Cachar, Sylhet, Manipur, Looshai Hills, 

 Tippera, and Chittagong, being replaced in Arrakau by the 

 next subspecies. 



I can find no name applicable to this bird, and name it 

 in honour of Count Nils Gyldeiistolpe, who has done so 

 much good ornithological work iu the east with the Swedish 

 Mission. 



■)- (3) Picus canus hessei. 



Gecinus canus hessei Gyldenstolpe, Orn. Monatsb. xxiv. 

 1916, p. 28. 



Type locality. Pak Koh and Deuchai, northern Siam. 



A rather larger bird, tlie wings of the specimens examined 

 by me (60 birds) varying between 140 and 157 mm., and 

 averaging 148 mm. Gyldenstolpe's, Herbert's, and Kloss's 

 birds vary between 140 and 155 mm., and average the same 

 as the Museum birds, 148 mm. 



Differs from P. c. gyldenstolpei in being greener and in 

 having no bronze-yellow reflections on the upper plumage 

 and wings. It diff"ers from G. c. occipitalis in being rather 

 smaller, more green and duller both above and below. 

 There is also decidedly more yellow on the rump and upper 

 tail-coverts.
