Birds of Celebes: Muscicapidae. 
373 
It appears to be nearly related to S. philippinensis Sh., a considerably larger 
form: wing 79 as against 69 mm (Sharpe). >S. hanyumas of Celebes may be 
distinguished by its entire under surface of orange-rufous and by its black cbin 
and sides of throat. 
Among the Muscicapidae there is no species connecting the Australian Region 
with Celebes, since Australian forms which reach Celebes pass on into the other 
Great Sunda Islands, the Philippines, or further. This is of interest from the 
fact that the Australian Region rivals Africa in the question as to which area 
possesses the greater number of peculiar Muscicapidine genera. Celebes viewed 
as Australasian ground might be expected to have a share of the peculiar 
Australian Flycatchers. On the other hand several Oriental genera connect 
Celebes with the countries to the west, without passing into the Moluccas on 
the east. Siphia is one of these, its range being from the Himalayas and East 
China to Celebes, Java, and Timor. 
* 127. SIPHIA BONTHAINA Hart. 
Mountain Flycatcher. 
Siphia bonthaina (1) Hart., Nov. Zool. 1896, 157; (2) id., ib. 1897, 158. 
Male. “Above olive, quills margined with rufous-brown on the outer webs and with light 
brown on the inner webs. Tail deep chestnut, more brownish on the tip ; upper tail- 
coverts of the same colour. A large spot over the lores; from the base of the bill 
to the middle of the eye pale ochraceous. Chin, throat, and breast light ochraceous. 
Abdomen white, bases of feathers slate-colour. Under tail-coverts white with an 
ochraceous shade; under wing-coverts very pale brownish. L. t. about 11(1 mm; wing 
65; tail 47” (Hartert 1). 
“Iris deep chestnut; feet slaty grey, soles pale reddish; bill black” (Doherty 2). 
Female. “Has the wing only 61 mm, the tail 45 mm, and the chin, throat, and breast are 
very much paler than in the male” (Hartert I). 
Distribution. Mountains of Celebes: Bonthain, c. 6000 ft. (Everett, Doherty). 
At the time of writing, the only specimens of this species known are three 
— two males and a female in the Tring Museum. They bear much resemblance 
to the female of the lowland S. rufigula, and may probably be regarded as re- 
presenting a lowly organised species in respect of coloration. Mr. Hartert, 
who has carefully established the validity of this form, writes in lit.; “The 
upper side of <S. honthaina is olive (without any greyish tint in it), Avhile it is 
olive-grey in the female of rvjigula. The tail of S. honthaina is chestnut through- 
out, while it is deep brown with chestnut outer margins in 6^. rufigula Q”. 
He adds (2): “The wing of S. rufigula is decidedly shorter, measuring only 
57 mm^). The tarsus of 8. rujigida is much shorter 16 mm (19 to 20 in /S. 
honthaina ) . 
1) In the Sarasins’ example 60 mm.
