In dealing with this species Baker states that the type locality 

 is the Himalayas, and that it is confined to these mountains as far 

 east as the Mishmi Hills (Journ. Bombay N. H. Soc. xxvii, 1921, 

 p. 488; M., p. 202). This is incorrect: the type of A. superciliaTis 

 came from the "mountainous interior of Tenasserim", and the Hima- 

 layan bird is Ahrornis fiaviventris Jerd. (Birds of India, ii, 1863, 

 p. 203.- Darjeeling), 



A. s. superciliaris ranges southwards as far as Bandon in 

 Peninsular Siam ; birds from Perils and Perak are intermediate 

 between it and A. s. schwaneri of Borneo, which is also found in 

 Selangor and Negri Sembilan, Malay States, and which differs only in 

 rather larger size; wings 51-56 mm. against 45-51 in the typical 

 race : there are no colour distinctions. 



Five specimens from Borneo have wings 51, 52, 53, 53, 

 56 mm. Seven specimens from Negri Sembilan and Selangor have 

 wings 50, 52, 52, 52, 54, 55 mm. Four specimens from Perak and 

 Perils have wings 50, 51, 52, 52 mm. Five specimens from Bandon 

 have wings 45, 49, 49, 50, 50 mm., while the present examples from 

 the Isthmus of Kra range between 45-51 mm.
