The o.istorn form of ^1. bxecoidc.^, A. h. (jcixlrrorum Mey., is closely allicil to 

 .1. b. bm-coidrs, differing only in its lighter, more cinnamon-brown crown, and 

 frequently (though not constantly) larger black spotting of the chest. No other 

 differences seem to be constant. Yonng birds of both forms, recognisable by their 

 blackish bills, have a darker, more olive crown, with a more or less marked, paler, 

 irregular mesial line. While examples from the Berau Peninsula and Waigin 

 (typical baccoi(lcs) are easily distinguishable from typical qcislfroram from Kaiser 

 Wilhelm's Land and Gollingwood Bay, those coming from the north coast of New 

 Guinea, east of Geelvink Bay, are somewhat puzzling. The specimen from Takar 

 (Doherty) cannot be separated from gei.sleronim, while those coming from Brnijn's 

 hunters, said to be from the same neighbourhood, i.r. from the north coast 

 between long. 1.36" and 137' E., agree partly better with hurrnhlr^, partly with 

 ffeiskrorum. It is not impossible that one or the other of these has the locality 

 erroneously marked, but it is also possible that they all should be united with 

 geislerorum, as those which are more like adult buccoiiles may be immature 

 geislerorinn.

 very dark. 



In the Ticvreich (]). 7) one of us treated this form as .spceifieally distinct from 

 A. melanotiH ; but having examined so many more specimens, he is now convinced 

 that it can only be treated as a subs))ecies, though being much more distinct from 

 the two other forms of .^1. ■melanotis than they are from one another,
