Mr. R. Swinhoe on Formosan Ornithology . 313 
swinish herds from their rambles about the streets to the troughs 
to be fed, I name our bird 
TrERON CHQSROJBOATIS, sp. UOY. l/V 
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 differences, she resembles the female of 
Treron 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 yellow as 
stated by Dr. Jerdon. The Chinese of the interior call this Pigeon 
the Swa Hwun cheaoUy 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 9 (plate 17) as Muscicapa luteola ,
