Genus— CAMP BELL ORNIS. 
Campbellornis Mathews, Austral Av. Rec., 
Vol. I., pt. 5, p. 113, Dec. 24th, 1912. 
Type (by original designation) ... ... Ocypterus personatus Gould. 
This very distinct group I thus characterized : “ Differs from Artamus in 
its longer, more curved and much narrower bill, and its comparatively longer 
tail, though shorter wing.” 
The bill is long and narrow-, and comparatively delicate, the culmen 
regularly arched, the tip quite pointed and the edges of the upper mandible 
slightly sinuate, expanding a little basally and overlapping the edges of the 
under mandible ; the under mandible has the gonys narrow and almost 
decurved, the interramal space less than the gonys, and the rami slightly 
divergent, showing a narrow fully-feathered space ; the nostrils are circular 
in a depression, not a well defined groove, and are open, not hidden by 
feathering as in the preceding. 
The tail is longer and the wing is shorter, so there the proportions differ, 
so that the tail is about two-thirds the length of the wing. In other structural 
features this is quite like the preceding.
