THE BIRDS OF SOUTH-WEST AND PENINSULAR SIAM. 145 



We are unable to say if the darker form described bj'- the 

 late Col. Harington as C. p. coohi from the Northern Shan States 

 (Bull. Brit. Orn. Club, xxxi, 1913, p. 57 : Goteik, N. Shan States) 

 occurs in Peninsular Siam ; the probabilities are that it does, as 

 we have one specimen closely agreeing with the description, shot on 

 the summit of Kedah Peak in December 1915.
