LEMON-BREASTED FLYCATCHER. 
practised eye can detect it. ‘ Keep your back to the sun ’ seems to be its 
motto, for we have not observed it in any other position. As the sun goes 
round, so also does the young Flycatcher.” 
McLennan ’s notes, published by H. L. White, read : “ Macarthur River, 
7/8/15, and Liverpool River, 21/9/15. Fairly plentiful all along the rivers. 
King River, numerous in mangroves, rarely seen in forest. Port Bradshaw, 
5/2/16. A few noted in the forest country.” 
Gould described this species from Port Essington, Northern Territory, 
and no subspecies were separated until I drew up my “ Reference List,” when 
I differentiated the Queensland race and later the Melville Island form was 
named by me. 
In the Bull. Brit. Orn. Club , Vol. XXXVII., p. 4, Oct. 24th, 1916, Lord 
Rothschild described Microeca flavigaster loetissima : “ Differs from Microeca 
flavigaster fiavigaster by its longer wing, much paler underside, and slightly 
less brownish crown of the head ; from M. fiavigaster Iceta by the much paler 
underside and somewhat duller coloration of the upper-side ; this would have 
to be said also of M. f. terrceregince Mathews, which is very closely allied to, 
if at all separable from, M. f. Iceta. Wing of six specimens of M. f. Icetissima , 
78-83 mm. Hab. Queensland (Bowen, Cardwell, Mulgrave). Type from 
Cardwell.” 
In this connection geography appears to have been forgotten, as Microeca 
Iceta was described by Salvadori (Ann. Mus. Civ. Genova , Vol. XII., p. 323, 
1878) from Vandamen in the Bay of Geelvink, Arfak Peninsula, north New 
Guinea. If the Cardwell bird could differ from the bird from Cairns it would 
not do to unite that with the northern New Guinea form. As a matter 
of fact Ogilvie-Grant (Ibis, Jubilee Suppl. No. 2, Dec. 1915, p. 173) found 
that a single female from the Mimika River, south-west New Guinea, was 
more like the typical bird than the Cairns form, which he considered easily 
distinguishable. 
My M. f. terrceregince was characterised thus : “ Differs from M. f. 
fiavigaster in its distinctly greener coloration above and brighter yellow 
underneath,” and M. f. melvillensis “ Differs from M. f. flavigaster in its 
lighter coloured yellow below and very much less green on the back.” 
Birds collected by Cockerell (at Cape York) seem to resemble those from 
Port Essington, while a bird from Port Moresby, S.E. New Guinea, is also 
like that form and easily separable from M. f. terrceregince by its duller 
coloration. 
Four subspecies can be accepted : 
Kempia flavigaster flavigaster (Gould). 
Northern Territory ; North-west Australia.
