swinish herds from their rambles about the streets to the troughs 

 to be fed, I name our bird 



Treron chceroboatis, sp. nov. 



The female has the belly white, the lateral rectrices black 

 tipped with green, the two middle pair somewhat sinuated on 

 the edge of the webs within "75 inch of their tips, and pro- 

 tracted beyond the rest, the longest about "5, the next about '2. 

 It is impossible to guess what the male will be like. The bill of 

 the female bird is a trifle smaller ; but otherwise, with the excep- 

 tion of the above-noted diflferences, she resembles the female of 

 Trei'on formosce. 



On the 27th of January, 1866, from the same mountains was 

 brought to me a Cushat or Wood-Pigeon, which answers in 

 every respect, both of colour and size, to Palumbus pulchricollis, 

 Hodgson, of Nepal, as described by Dr. Jerdon (Birds of India, 

 iii. p. 465). I have no specimens from India to compare 

 with mine, and therefore cannot state that it is positively iden- 

 tical, and has not varied at all from isolation. But it is an im- 

 portant fact that in India an allied form, P. elphinstonii (Sykes), 

 should occur, and yet that at this distance the species should 

 recur in apparently its entire originality. It adds one more 

 valued addition to the numerous other cases indicating the 

 strong affinity of our mountains with those of the distant Hima- 

 layas. The claws of our bird are yellowish, and not yelloiv as 

 stated by Dr. Jerdon. The Chinese of the interior call this Pigeon 

 the Swa Hivun cheaou, or Hill-Pigeon, and say it only appears 

 when rice is scarce. 



I received at the same time with the last quite an immature 

 specimen of a Dove of the Turtur rupicola type. If it be, as I 

 take it, identical with this species, we shall learn from it that 

 T. rupicola breeds in Formosa, and also that it participates in the 

 peculiar habit of many other Doves, of nesting sometimes in the 

 depth of winter. 



From Choloshan (Central Formosa) I have a small Flycatcher, 

 shot in October. It answers in every respect to that figured in 

 Middendorff's ' Sibirische Reise ' (plate 17) as Muscicapa lateola,
