YELLOW-BILLED KINGFISHER. 
Further, he determined Syma megarhyncha Salvador! as a distinct species, 
but this seems too high a value : it appears merely to be a mountain form 
of the species, and if this be conceded then the south-west New Guinea birds 
would be distinguishable from the south-east New Guinea specimens. Upon 
comparison I find this to be so. 
I would therefore range the species in many subspecies, and as it seems 
a variable bird as regards geographical conditions, it is possible still more 
will be recognised. Above I observed that 8. megarhyncha did not concern 
us, but reconsideration suggests that it is merely a mountain form of this 
bird, so that it must be included in a review of the species, which is 
represented by nine recognisable subspecies. Six of these have been already 
named, while the two south-western New Guinea forms are nameless. The 
necessity of naming the lowland race is evident, inasmuch as van Oort 
considered it nearest 8. t. tentelare Hartert; Rothschild and Hartert thought 
it might be their 8. t. meelci, while Ogilvie-Grant declared it to be typical 
8. t. torotoro. I propose, therefore, to name it 
8y7na torotoro pseustes, subsp. n. 
The type is in the British Museum. 
The race is smaller than the typical subspecies and differs from 8. L 
meeki in coloration, the upper surface of the tail being more bluish and the 
general tone of the upper surface darker. 
The specimens recorded by Ogilvie-Grant as 8. megarhyncha from the 
Utakwa River must also be named. The male is obviously separable by 
the bluish back coloration and the paler head. That this bluish colour is 
subspecific is seen in the female and young male also collected. The difference 
in coloration is as distinctive (or more so) as that accepted by Ogilvie-Grant 
in the case of 8. t. fiavirostris and 8. t. torotoro. It is noteworthy that these 
two mountain forms should be similar so many miles apart. I propose for 
Syma megarhyncha Ogilvie-Grant {Ihis, Jubilee Suppl. No. 2, 1915, p. 211), not 
of Salvador!, the new name 
Syrrm torotoro wellsi subsp. n. 
The type is in the British Museum. 
The coloration of the bill in the genus is interesting. In the immature 
it is wholly black, while in the typical subspecies in the adult it is wholly 
unicolor, yellow of some shade. In the Cape York subspecies, 8. t. fiavirostris^ 
a black streak along the culmen is retained and this has been used as a 
differential feature of this race. Cockerell, however, collected some birds as 
at Cape York, and two of these show yellow bills, two have the black stripe. 
As far as can be gauged these were procured at Cape York, or else some locality 
other than the Aru Islands, as they do not agree with Aru Island birds but
