1875.] MR, R. B. SHARPE ON BIRDS FROM LABUAN, 109 
for it even traverses obliquely the inner web to within ;4, inch of its 
apex. 
ie sene One bird, sent by Mr. Lowe.—Very slight shade of 
grey on the wings, but seen also on the secondaries. Tail imperfect, 
the white extending to within 0°45 inch of tip of outer rectrix. 
Slight remains of greyish spots at the end of some of the tail- 
coverts. 
Bouru. Three specimens, agreeing well together, were received by 
the Museum from Mr. Wallace’s collection. —The markings on the 
tail being more black and extended refer the species to the C. mela- 
nura of Gray. Wings black with very faint shade of grey. Tail- 
feathers 14, the white extending to within 0°65-0°9 inch of the tip 
of outer rectrix. Both specimens well marked with black on abdo- 
men and under tail-coverts. 
Gilolo. One specimen, collected by Mr. Wallace and referred by 
him to C. melanura of Gray.—Wings black, with very slight grey 
shade. No black spots on abdomen. ‘Tail-feathers 14, with the 
white on the outer one reaching to within 0°6 inch of the tip. 
Batchian. A single bird in Mr. Wallace’s collection is the type 
of C. melanura, and bears the label in Mr. Gray’s handwriting 
‘‘outward feathers not white.” The latter gentleman refers the 
foregoing Gilolo skin to this same species ; but the tail is differently 
marked in this one, and the abdomen thickly spotted with black. 
Wings black, with a slight grey shade. Tail-feathers 12; but it is 
quite probable that the outer feather on each side is missing ; and the 
disappearance of the oblique white marking of course would leave 
the black forming a tolerably broad band across the extremity of 
the tail, as it does in nearly every example of the group. 
Ceram. Mr. Wallace collected one specimen in this island, much 
marked with black on the abdomen. Wings black, very plainly 
shaded with grey on both primaries and secondaries. Tail-feathers 
14, the white descending on the outermost one to within 0°7 inch of 
the tip. 
Ee eend From this island we have also one specimen, a male, 
collected by Mr. Wallace in 1859. Both the abdomen and under 
tail-coverts are thickly marked with black. Wings black, slightly 
shaded with grey. Tail-feathers 14, with the white extending to 
within 0°85 inch of the tip of the outermost. 
New Guinea. Mr. Wallace has determined a specimen collected 
here by himself as C. dicolor ; and I do not see to what else it could 
be referred. The under surface is entirely white, with only a small 
blackish spot at the tip of the longest under tail-coverts. Wings 
black, very strongly shaded with grey. ‘Tail of 14 feathers, the 
white extending to within 0°55 inch of the tip; but on one side it is 
more extended and reaches nearly to the tip of the outer web, occu- 
pying a large subterminal portion of this feather. 
Aru Islands. Two birds collected here by Mr. Wallace are de- 
termined by Mr. Gray as “ C. spilorrhoa, var.” They are rather 
large, and have a good deal of grey shade on the wing, the vent and 
under tail-coverts distinctly spotted with black. Tail-feathers 14 in
