DESCRIPTIONS OF TWO NEW SPECIES OF BIRDS FROM THE 
BOROR DISTRICT OF PORTUGUESE EAST AFRICA. 
By Alwin Haagner, Assistant, Transvaal Museum. 
In December, 1908, the Transvaal Museum acquired a fine collection 
of about 400 birds, collected by Messrs. F. Vaughan-Kirby, F.Z.S., and 
Austin Roberts in the Boror District of Portuguese East Africa. A full 
account of the collection will appear later, either in the “ Annals ” or in 
the journal of the S.A.O.U. The Boror district is that portion of 
Mozambique Territory lying just north of the Zambesi River. The collec- 
tion was made in a comparatively restricted area, the party never having 
been further north than the 17tli degree of south latitude, nor further 
west than the 36th degree. 
Amongst this collection there are several new to science. My thanks 
are due to Dr. Reichenow for kind assistance in verifying and comparing 
birds for me. 
Anthoscopus robertsi, sp. nov. 
Above pale grey-brown, with a distinct yellow-olivaceus tinge. Fore- 
head, eyebrow, and cheeks pale cream ; the latter washed with ashy. Throat 
and upper breast creamy-white passing into cream colour on the lower 
breast and sides of the body. Abdomen and flanks pale rufous-brown. 
Thighs pale yellowish. Upper tail coverts slightly washed with pale 
ochresous-brown. Wing-coverts grey-brown, edged with pale sandy-grey. 
Remiges ashy-brown edged with creamy-white on the outer web, and with 
very pale isabelline on the inner. Axillaries and under wing-coverts silky- 
white. 
Measurements of skins : (a) Female (type). L. 78. Wing 53.4. Tail 
29.5. Tarsus 13. Culmen 8.8. 
(Iris brown. Bill bluish-slate, dark-brown on the culmen and genys. 
Tarsus pale cobalt-blue. L. 77. W. 52. C. 9. K. & R.) Boror (Villa 
Pereira), 17th May, 1908. 
(b) Female (co-type). Length 78. Wing 50. Tail 26.5. Tarsus 
12.5. Culmen 8.6. (Iris pale slate. Bill slate, tomia whitish. Tarsus 
slate. L. 75. W. 48. C. 8. K. & R.) Villa Pereira, Boror, Port. 
S.E. Africa, 5th May, 1908. 
The second example has the wing-plumage in a somewhat worn condi- 
tion, hence the smaller measurement. 
This new species comes nearest to A. caroli Sharpe, but differs 
markedly from this species in the clear olivaceus grey upper surface, and 
white under wing-coverts. 
Heliolais Jcirbyi , sp. nov. 
Similar to H. erythroptera (Jard.), from which it is chiefly distinguished 
by its isabelline-brown upper surface, instead of grey-brown, and by its 
smaller size.
