DESCKIPTION OF A NEW SPECIES OF COLLYRIOCINCLA— NORTH. 49 



DESCRIPTION OF a NEW SPECIES of C0LL7RI0CINCLA 

 FROM QUEENSLAND. 



By Alfred J. North, C.M.Z.S., 

 Ornitholo£rist to the Australian Museum. 



COLLYRIOCINCLA CERVINIVENTRIS, Sp. UOV. 



Adult male. — General colour above greyish-brown very slightly 

 shaded with olive, clearer grey on the head ; wing-coverts like 

 the back, the quills brown washed with olive on their outer webs, 

 and externally edged with grey ; tail brown, the two centre 

 feathers, and the outer webs of the remainder, shaded with grey; 

 feathers in front of the eye dull white; ear-coverts pale brown with 

 narrow white shaft streaks ; cheeks and throat white, slightly 

 tinged with buff; remainder of the under surface and under 

 wing-coverts pale fawn colour, the feathers on the chest shaded 

 with grey ; bill and legs fleshy-brown. Total length 7*2 inches ; 

 wing 3'7, tail 3"2, bill 0"87, depth at nostril 0'25, tarsus 1"02. 



Hah. — Dawson River, Queensland. 



Type. — In the Australian Museum, Sydney. 



Ohs. — Another specimen, probably a female has the primary- 

 coverts and outer webs of the secondaries washed with rufous- 

 buff. This is the inland representative of C. rufigaster of the 

 coastal brushes, from which it may be distinguished by its 

 longer and thinner bill, and by its very much paler upper 

 and under surface. In all the specimens from this district — 

 three in number — the distinctive characters of this species are 

 constant. 



Eggs of this closely allied species were described by me in the 

 " Nests and Eggs of Australian Birds," * under the name of 

 C. rufigaster. 



The type of C rufigaster was obtained in the brushes of the 

 Clarence River, New South Wales. An adult male from this 

 locality measures: — total length 7*3 inches; wing 3-9, tail 3-3, 

 bill 0-8, depth at nostril 0*3, tarsus 1-08. A large series of 

 specimens from the coastal districts of Queensland, as far north 

 as Cairns, vary only in wing measurement from 3 '8 to 3*9 

 inches.
