On Phapitreron. 



There is no doubt, in our opinion, that levcotis, occipitalis, hrevirostris , 

 samarensis, and nigronim must be treated as subspecies, and leucotis is the oldest 

 name. 



The specimen from Sulu appears to belong to a new form, having the wing 

 shorter, while agreeing in colour very much with hrevirostris, though the throat 

 is more as m leucotis. More specmiens from Sulu will no doubt prove it to be a 

 new subspecies. Macgregor, Manual Philipp. B. i. p. 35, suggests " that there 

 must be something wrong about the Sulu record of P. hrevirostris." There is, 

 however, nothing wrong about it, except that it can hardly be hrevirostris. The 

 specimen, sexed $, is labelled " Mainbun, Sulu Island, 24. iv. 1883. Length, 

 23 centim. Iris outer ring red, inner white. Bill brownish. Tarsus dull coral 

 red," by Dr. H. Guillemard, and the label is the original one. 



It may be remarked that the forehead, which is described as " white," is 

 never quite white, but only whitish, or bufiy whitish, in P. leucotis samarensis 

 and alhijrons. 



The forms of Treron calva. 



The various forms of the African Bald-fronted Fruit-Pigeons have hitherto, 

 chiefly for want of sufficient series from all localities, not been well understood. 

 After comparing our material of 91 specimens and an examination of the still 

 longer series in the British Museum by one of us (Hartert), we think that we 

 can throw some further light on these birds, without, however, in any way 

 reaching finality and solving all questions. 



In the Cat. B. Brit. Mus. xxi. pp. 20-25, 1893, " Vinago " calva and 

 nudirostris were united, while wakefiehli, schalowi, and clehdnndei were kept as 

 different species. From the distribution of icakejieldi it would indeed seem that 

 the forms with a greenish tail cannot be subspecies of calva, and we shall not, 

 therefore, discuss these latter forms at present ; with regard to calva Salvadori 



* Hellmayr, Avij. Timor, p. 8G, calls this form reginun, but as Swainson spelled the name 

 with a capital R it is not an adjective, l.>ut a substantive. It is important that the original spell- 

 ing is copied in quotations !
