TROCHALOPTERON MILNEI SHARPEI Rippon 



Trochalopterum sharpei Rippon, Bull. Brit. Orn. Club, vol. 12, p. 13, 1901 (Kauri- 

 Kachin tract, east of Bhamo, Burma). 



Seven males and nine females, Doi Nangka, November 9, 1930 

 (one), and April 22-27, 1931; one male. Pang Meton (Doi Nangka), 

 May 5, 1931. 



\Mnle there is no comparative material available, the specimens 

 seem to fit the description of this form, which is found in the northern 

 Shan States, in the Kachin Hills, Burma, and in Yunnan. 



T. m. vitryi (Delacour) has been described from the Plateau des 

 Bolovens, southern Laos. T. m. indochinev sis Delacour was named 

 from central Tonkin. T. m. milnei David is a local race occurring 

 in the mountains of northwestern Fohkien, southeastern China, and, 

 so far as known, is more or less isolated. 



This is another fine race that Dr. Smith was the first to add to the 

 Siamese avifauna. It has been previously recorded by me.^° 



TROCHALOPTERON MELANOSTIGMA MELANOSTIGMA (BIyth) 



Garrulax vielanostigma Blyth, Journ. Asiat. Soc. Bengal, vol. 24, p. 268, 1855 

 (Mount Muleyit, Tenasserim). 



One male and one female, Doi Angka, 6,500-7,500 feet, December 

 1 and 4, 1928; one male, summit of Doi Sutep, December 15, 1928. 



These three specimens differ from a male from Mount Nwalabo, 

 Bunna, ramsayi, as follows: The back is more of a deep grayish olive 

 rather than brownish ohve; the lowerparts are grayish instead of 

 ochraceous-tawny ; the jugulum is darker and very restricted, not 

 extending onto the chest; the lores, chin, and throat are more exten- 

 sively black; the spot on the greater wing coverts is sudan brown 

 instead of sanford brown. 



The specimens do not agree exactly with Stuart Baker's description 

 of melanostigma, but I have no material for comparison. 



This species is usually made a form of T. erythrocephalum, but in 

 my opinion it belongs to a different form group. 



Deignan ^' reports this form as rather common on Doi Sutep from 

 4,600 feet to the summit. 



It ranges in the mountains from Tenasserim northward into the 

 Shan States of Burma and in northern Siam. The nearest relative 

 appears to be T. m. connedens Delacour of Laos and Tonkin.
