NO. 2276. REVISION OF SAUROPATIS CHLORIS—OBERHOLSER. 



381 



The bird from the Pagi Islands appears to be the same as that 

 from Simalur Island, though we have but a single example, and 

 that a female, for comparison. Birds from the Batu Islands are 

 somewhat lighter in color above than typical Sauropatis chloris 

 chloroptera from Simalur Island, and also average slightly smaller ; 

 but these differences do not now appear significant enough for sub- 

 specific distinction. These Batu Islands birds are, in fact, interme- 

 diate between Sauropatis chloris chloroptera of Simalur Island 

 and Sauropatis chlons amphiryta of Nias Island,^ but arc nearer the 

 former, with which, for the present, we include them. Average 

 measurements of examples from the different islands compare as 

 follows :
