$42 MR. A. R. WALLACE ON THE BIRDS [DeC. 9, 



alarum nigris, olivaeeo marginatis; rostro nigroy pedihus ob- 

 scuris, 



Foem. ohscurior ; capitefusco; gula albescente ; pectore et abdo- 

 mine pallide rufis ; crisso flavescente j tectricibus caudcB infe' 

 rioribus Jlavis ; alls caudaque olivaceo-brunneis. 



Very like Pachycephala melanura, Gould, from which it differs 

 only in the broader pectoral band, the rather larger size, and the 

 upper tail-coverts, which are black ; whereas by Gould's figure and 

 description they are olive-yellow or green, like the back. 



Total length 6f inches ; wing 3| inches. 



Sab. Sula Islands and Bouru. 



Remarks. — The genus Pachycephala does not occur in Celebes ; so 

 that we must consider this bird to have come from the Moluccas ; 

 and it already shows slight differences, which may be taken as indi- 

 cations of its becoming modified, into a distinct race, 



DlCRURUS PECTORALIS. 



Nigro-ceeruleus ; alls nitide eeneis ; pinmis pectoris maculis magnis 

 pwpureo-eeneis terminatis ; colli plumis lateralibus, elongatisp 

 purpureo-nitidis. 



Rich bine-black ; wing of a brilliant metallic-bluish green ; the 

 feathers of the head and breast terminating in metallic purple spots, 

 which on the breast are large and very conspicuous ; sides of the 

 neck with elongated metallic-purple plumes ; the tail and rump also 

 have metallic tinges ; tail rather short, and moderately forked and 

 recurved ; bill moderate ; iris red. 



Total length 1 2 inches ; wing 6 inches. 



Hab. Sula Islands. 



Remark. — This fine species seems distinct from any of its allies : 

 it is most like the Celebesian form ; but that has always a white iris.
