C. strepera Latham —

C. fuliginosa Gould. 
Strepera arquta Gould. 
Largest Cracticine birds with long bill, long wings, long tail and short stout 
legs and strong feet. 
The bill is conical, longer than the head, the culmen more or less arched, 
basally flattened, anteriorly semi-keeled and laterally compressed, the tip 
short, sharp and decurved with a posterior notch, the edges of the mandibles 
straight behind the notch ; the depth of the upper mandible at the base 
equal to basal breadth ; the culmen is rounded at its base into a semi-shield ; 
the nasal groove has disappeared as in the preceding Cracticine forms, the 
nostrils appearing as linear slits with scarcely a depression evident, placed 
so near the frontal feathers, which approach a little, that the appressed nasal 
bristles reach over the nostrils ; these are few however and scarcely noticeable ; 
the rictal bristles are six in number, two or three longer and more pronounced ; 
the under mandible is stout at the base, about half the depth of the upper ; 
owing to the compression only a narrow triangular interramal space is seen, 
less than hah the length of the under mandible which has an upcurved hooked 
tip ; the gonys is angulate and keeled and anteriorly strongly laterally 
compressed. 
The wing has the first primary short, about half the length of the third 
primary and shorter than the secondaries ; the second is a little longer than 
the eighth primary which exceeds the secondaries ; the third a little longer 
than the seventh, and a little less than the third, fourth and fifth primaries, 
which are subequal and longest. 
The tail is long and slightly rounded in shape.
