GENUS RHIPIDURA. 87 
described by Dr. A. B. Meyer in the above cited Sitzungs- 
berichte. 
b. Second stage: Female, collected by S. Müller, 
together with the typical specimen at the bay Lobo, 
S. W. New Guinea. General color above and below con- 
siderably much paler than in specimen a, probably owing 
to its having, as a stuffed specimen, been much more ex- 
posed to the light. The white on chin and throat extend- 
ing upon the cheeks, the chest grayish olive instead of 
olive-brown, each feather bearing, in its centre, a large 
cordiform dirty white spot of four millimetres in width. 
No black at all on the chest, the outermost of the under 
wing-coverts edged with white, lower mandible white with 
a blackish mark near the tip. Wing 7,5 cm, tail 9,4, 
tarsus 2,2, culmen 1,5. 
c. Third stage: Female, collected by Bernstein at 
Sorong, January 20th 1865. Differs from the preceding 
specimen in having the head and back less tinged with 
rufous, in being more ashy olive on chest and breast and 
in having the cordiform spots much purer white and on 
most of the feathers, especially near the throat, encircled 
with black. Under wing-coverts as in the previous speci- 
men. Hardly any black at the tip of lower mandible. 
Wing 8 em., tail 9,2, tarsus 2, culmen 1,7. 
d. Fourth stage: An unsexed specimen from New 
Guinea (Frank, 1873). Similar to the former specimen, 
but having the white spots on the chest very large with 
all the surrounding parts of each feather entirely black, 
while many of the grayish olive breast-feathers, especially 
on the centre of the breast, bear concealed white, cordi- 
form spots without black surrounding. Under wing-coverts 
very conspicuously tipped with white, and some of the 
outermost lesser wing-coverts also tipped with white. Lower 
mandible entirely white. Wing 8 cm., tail 9,8, tarsus 2,3, 
culmen 1,7. 
e. Fifth stage(?). Type of the species (<’), collected 
by S. Müller at the bay Lobo, S. W. coast of New Gui-
