It is curious that Davison should not have obtained this 

 barbet at Pakchan Estuary, as it was very common both on the 

 Siamese side and at Victoria Point, where its gong-like note at once 

 attracted attention. 



Our considerable series noted above is very constant both in 

 size and colour, the dark edges to the feathers of the breast being 

 not nearly so marked as on the birds from Eastern Siam, which are 

 freshly moulted. 



The racial divisions as laid down by Baker seem well justified, 

 but we should like to hear more details about the type of Megalaeina 

 maclellandi Horsf. and Moore, from Assam. It is within the bounds 

 of possibility that this name is the one really applica^ble to the 

 present form. 



As noted in the synonymy, the species spreads as far south as 

 the coast of Trengganu. It has never been obtained in the Federated 

 Malay States.
