Pcecilodryas sylvia, Ramsay, Trans. Linn. Soc. N. S. Wales, viii. p. 5 (1883). 
The genus Pcecilodryas consists of two groups, or sections, characterized by the colour of the abdomen ; in 
one section the abdomen is white, in the other yellow. The white-bellied group may be further subdivided 
into those which have the throat white and those which have a black throat. The present species belongs to 
the latter section, which now contains three species — P. bimaculata , P. cethiops, and P. albinotata , the latter 
being distinguished by its bluish-grey upper surface. 
P. bimaculata and P. cethiops have the upper surface black, with the rump and upper and under tail- 
coverts white ; but they may easily be distinguished from each other, P . bimaculata having the abdomen 
white, a long white patch on the sides of the fore neck and chest, and the inner wing-coverts black ; whereas 
in P. cethiops the abdomen is black, the inner wing-coverts are white, forming a shoulder-patch, and there 
is no white on the sides of the fore neck. 
The present species was discovered in north-western New Guinea by Signor D’ Albertis, and has been met 
with in the same locality by Dr. Beccari and M. Laglaize. It has been more recently obtained in the 
Astrolabe Mountains by Mr. Goldie, and a specimen from that range of mountains has been lent to me by 
Mr. Ramsay. 
The following description is copied from the ‘ British Museum Catalogue of Birds ’ : — 
“ Adult male. Above velvety black ; upper tail-coverts white, forming a band across ; wings and tail black ; 
sides of face, sides of neck, throat, and breast black, as well as the flanks and thighs ; abdomen, vent, and 
under tail-coverts white ; on each side of the chest a broad line of pure white feathers running from the 
sides of the lower throat to the sides of the upper breast ; under wing-coverts black ; quills ashy black below. 
Total length 5*1 inches, culmen 0‘6, wing 3*3, tail 2, tarsus 0*85.” 
The figures in the Plate, which represent an adult bird of the natural size, are drawn from the Astrolabe- 
Mountain specimen lent to us by Mr. Ramsay, the type of his P. sylvia. [R. B. S.]
