pale yellow throaty and the upper parts are greenish. The 

 others have faded to grey above and white below, with a trace 

 of brown on the breast and flanks. 



It is impossible to say whether they represent a new species 

 or not. They do not difi'er in dimensions from the Japanese 

 species. 



Fringilla kittlitzi. 



The Bonin Island Greenfinch was common. Three examples 

 sent. 



FaLCO PEREGRINUS. 



Four or five pairs of Peregrine Falcons frequented the rocks 

 near the centre of the island, and appeared to live principally 

 upon Bulwer's Petrel, which was very abundant. Two ex- 

 amples sent. 



COLUMBA lANTHINA. 



The Pigeon of Sulphur Island seems to be the Japanese 

 species, and not the fine bird of the Parry Islands {Columba 

 versicolor). It breeds on the island, but is not common. 

 This bird and its allies have evidently nothing to do with the 

 genus Carpophaga. I have recently examined large series of 

 both groups from Polynesia, and find that whereas the species 

 belonging to the genus Carpophaga have 14 tail-feathers, 

 those belonging to the subgenus lanthcenas have only 12 as 

 in typical Colwnba. There seems to me to be no reason 

 whatever why they should be removed from the genus 

 Culumba. Probably Gray was the first person who made the 

 mistake (Gray, 'Genera of Birds,^ ii. p. 469), which Jerdon 

 followed, to Blyth's astonishment (Blyth, Ibis, 1867, p. 149). 

 There seem to be also various anatomical peculiarities in 

 which these Pigeons differ from Carpophaga and agree with 

 Culumba. There does not appear to be any generic difference 

 between Columba ianthina of Japan and Columba laurivora 

 of the Canaries. 



The crown in newly moulted examples of Columba ianthina 

 is slate grey, glossed with pinkish purple. The purple gloss 

 seems to increase in amount with the age of the feather, 

 until it entirely hides the slate-grey ; but as it increases it
