is represented on the New Georgia gronp (New Georgiii or Hnbiana, Knlani- 

 Langra, Gnizo and Rendova) by one with dark thighs. A carefnl comparison 

 of the material from the Solomon Islands brings us to the conclusion that the 

 following forms are distinguishable : 



1. Asfiir etorqxes etorqi/cs Salvad., 1ST8 — New Guinea and some of the 

 adjacent islands. Colonr of ujiper throat grej-ish, generally with traces of bars, 

 and more or less merging into that of the breast and abdomen. Many appa- 

 rently adult specimens have partly barred undersides. Probably some of the 

 forms found on the small islands are again separable. 



2. Astiir efoi-i/iies (lumpicri Gurney, 1882 — Bismarck Arcliipelago. Differs 

 apparently in being paler and in having lighter under wing-coverts. We have 

 only seen a few specimens. 



3. Astur etorques bougainvillei snbsp. nov. — Bougainville Island, northern 

 Solomon Islands, and Shortland group. This and all the other forms from the 

 Solomon Islands have the throat and chin grey, sharply divided from the rufous- 

 cinnamon underside. Upper surface pale grey, lighter than in .1. e. nifoschiataceKn. 

 Wing, i, 194—109 mm. 



4. Aiitur I'torqi/es rufoscJiistaceiis Rothsch. & Hart., liM)2 — Isabel and Choiseul 

 Islands, northern Solomon Islands. Very similar to A. e. boiiyaindlli'i, but the 

 upper surface a little darker; wings longer, cf, wing 212 — 22ii mm., ?, wing 

 24()— 251 mm. 



5. Astur etorgi/es jnih-Iiellus Rams. 1881. — Guadalcanar and Florida Islands, 

 Solomon group. At once distingnishable by its light thighs and under wing- 

 coverts. 



6. Astur etorques rubianae subsp. nov. — Ruliiaua (New Georgia) group : New 

 (ieorgia, Rendova, (iizo. Darker and smaller than J. i\ riif'osckistfirpvs, especially 

 the under surface of a deeper, nearly chestnut colour. Wing, c? 19.5 — 200 ; ¥ 

 211— 214 mm.

Messrs. Meyer & Wigleswortli have separated three races of this species 

 (B. of Celebes, i. p. 84). 



1. F(dco severus ir/f/irtis from India. Said to be jialer aliove, with a brownish 

 slaty tail, and with tail and wings barred below on the inner webs.
