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



This species, although not confined to the Arrou Islands and to the Ki Islands, as I 

 have previously stated (I.e.), having been found quite recently along the Fly River, is 

 quite distinct from Trichoglossus cyanogrammus (Wagl.), with which it has been 

 assimilated by Wallace, Schlegel, and Finsch. 



I have seen many specimens of both species, and I have found that Trichoglossus 

 nigrigularis constantly differs from Trichoglossus cyanogrammus: — 



1st. In the red of the breast inclining to orange, paler and with a most conspicuous 

 yellow tint near the dark edges of the feathers. 



2d. The dark edges of the breast-feathers are much narrower, as in Trichoglossus 

 massence. 



3d. The head above has only two colours, blue in the anterior half, greenish in the 

 other half; while in Trichoglossus cyanogrammus the head above has three colours, blue 

 on the sinciput, green on the vertex, and purplish-brown on the occiput, like Tricho- 

 glossus massence. 



4th. The middle of the abdomen is generally blackish. 



5th. The dimensions are larger. 



The Ki Islands' specimens are a little larger than those from the Arrou Islands. 



9. Sauropatis chloris, Bodd.

[No. 244. Dobbo. Female. Legs slate, with a slightly bluish tinge ; eyes black. 

 Shot on Dobbo on the 20th September 1874.] 



This bird has the upper parts very dark, and in that respect approaches Sauro- 

 patis sordida (Gould), to which Mr Gray thought that the Arrou birds should be 

 referred ; but I have seen other specimens from the Arrou Islands with the upper 

 parts of a much brighter colour, exactly like others from Amboyna, Bouru, and other 

 localities. 



The true Sauropatis sordida (Gould) is a much larger bird. 



10. Sauropatis sancta, Vig. and Horsf. 



Halcyon sanctus, Sharpe, Mon. Alee*:!., pi. xci. (1868-71).

[No. 219. Wokan. Male (young). Eyes black ; upper mandible and edge of lower 

 black, under base of lower light coloured ; feet brown.]
