NOTE 



In Volume II, p. io6, I stated that I could not accept Acoimis inornattis Salvador! 

 even as a subspecies. This decision was based on the fact of the apparent indeterminate 

 variation shown by birds from all parts of the range and the consequent absence of 

 distinguishable subspecific foci. 



When I was working in the British Natural History Museum in 191 8 the skins 

 collected by Messrs. H. C. Robinson and C. B. Kloss in Sumatra in I9i4had not arrived. 

 With these there were a number of Acomiis which I had not thus the opportunity of 

 seeing, all of which are said to show the characters of A. inornatus. 



Mr. T. Wells of the British Museum, on his own initiative has very kindly called 

 my attention to this matter, and sent me the data in regard to these skins, which are all 

 from Sumatra. If in addition to the ten skins mentioned, there are besides "a good 

 many skins" with these characters, collected in Sumatra, then a fairly satisfactory case 

 is made for the occurrence of a subspecific focus in that island, and I am inclined thus 

 to recognise this form : 



Acomus erythrophthalmtis erythrophthalmus (Raffles). 



Habitat : Southern part of the Malay Peninsula and Sumatra, with subspecific 



focus in Johore. 

 Described in Volume II, pp. 105-107.
