72 THE VOYAGE OF H.M.S. CHALLENGER. 



I named this Ki Island's species (l.s.c.) before seeing a fully adult bird, feeling quite 

 confident, from Schlegel's description, that it was really distinct. I have recently examined 

 the adult specimens contained in the Ley den Museum, and I am satisfied that the Ki 

 Island's bird belongs to a peculiar form. I shall now give a full description of the adult 

 bird collected during the Challenger Expedition, and shall proceed afterwards to point 

 out its principal differences from the allied forms. 



Capite rufo-vinaceo, sincipite et genis pallidioribus ; vertice et occipite grisescentibus ;

 obsoletis adspersis ; gula rufescenti-albida ; collo antico et pectore summo vinaceis, 

 fasciolis transversis nigris notatis ; pectore imo et abdomine albido-fulvescentibus, fasciolis 

 transversis nigris notatis ; abdominis lateribus et subcaudalibus brevioribus pallide 

 cinnamomeis, nigro transfasciolatis ; subcaudalibus longioribus et tectricibus alarum 

 inferioribus cinnamomeis unieoloribus ; remigibus fuscis, exterius cinnamomeo limbatis ; 

 cauda superne brunneo-grisescente, inferne pallidiore et magis grisescente ; rectricibus 

 tribus utrinque lateralibus partita kete rufis, fascia lata subapicali nigra notatis ; rostro 

 nigro ; pedibus rubris. 



Long. tot. circa m '370 ; al. m 018 ; caud. m 190 ; rostr. ra 018 ; tarsi m 021. 



This species is intermediate between Macrapygia amboincnsis, Linn., and Macropygia 

 doreya, Bp. 



It differs from Macropygia amboinensis (which it much resembles in the light under- 

 parts) : — 



1st. In the greyish tinge of the vertex, of the occiput, and of the bind neck ; 



2d. In the more vinaceous colour of the front neck ; 



3d. In the more whitish underparts ; 



4th. In the darker hue of the back ; 



5th. In the larger dimensions.. 



From Macropygia doreya, Bp., to which it bears a great resemblance in the upper 

 parts, it differs : — 



1st. In the more greyish hind neck ; 



2d. In the much less vinaceous front neck and upper breast ; 



3d. In the more whitish underparts ; 



4th. In the lighter and more greyish tail ; 



5th. In the larger dimensions.
