or maybe slightly paler on an average ; in the latter case tliey wonld have to he 

 called .1. t. latiterbaclii {Arses Innterbachi Reichenow, OriK Monatsbfii-. 1897, ]>. 161), 

 iu the former A. lauterbachi is a synonym of .4. nnentalis. Evidently Professor 

 Reichenow, when describing ^l. lauterbachi, had quite overlooked Salvadori's 

 A. orieiitalis. In 1894 Madarilsz described another Arses from German New 

 Guinea, namely Arses fenicheli from Bnngu {Aquilu, i. pp. 92, 93). This bird has 

 a white alidomen and a grey, instead of black, crown, and the back is olivaceous. 

 What this bird may be, and how the adnlt male may look, we do not yet know, but 

 we have a similar bird, collected by the late (!arl Wahnes on Astrolabe Bay, 

 without date aiid exact locality. Probably .1. fenirheli is auother subs]>ecies of 

 Arses telesroplitJialmus. It may be added that the males of A. t. telescoplitkalmus 

 have more black on the chin, but that those of A. t. kenltei, A. t. orientulis 

 and (if that should be recognisable) A. t. lauterbachi, ajipear to be perfectly 

 indistinguishable.

Whether the birds from New Guinea are absolutely identical with those from 

 Australia we have not sufficient material (esjiecially females from Australia) to say. 

 Six females from Rossel Island, St. Aignan Island, and Arna River iu British New 

 Guinea have the rufons chest band of a much deeper colour, and more sharply 

 defined, than three females from N.W. Australia.
