342 MR. A, R. WALLACE ON THE BIRDS [Dec. 9, 
alarum nigris, olivaceo marginatis ; rostro nigro, pedibus ob- 
scuris. 
Foem. obscurior ; capite fusco; gula albescente ; pectore et abdo- 
mine pallide rufis; crisso flavescente ; tectricibus caud@ infe- 
rioribus flavis ; alis 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 63 inches ; wing 33 inches. 
Hab. 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. 
DicruRUS PECTORALIS. 
Nigro-ceruleus ; alis nitide eneis ; plumis pectoris maculis magnis 
purpureo-eneis terminatis ; colli plumis lateralibus, elongatis, 
purpureo-nitidis. 
Rich blue-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 12 inches; wing 6 inches. 
Hab. Sula Islands. 
Remurk.—This fine species seems distinct from any of its allies : 
it is most like the Celebesian form ; but that has always a white iris.
