I agree with Meyer [Sitzungsb. Ak. Wien, Ixix. Abt. i. 

 p. 507 (1874)], that in fully adult birds the upper back is 

 white with an irregular black patch confined to the middle oi: 

 the mantle. There seems to be no difference in plumage 

 between the male and female, but in the former the bill is 

 rather longer, measuring about 53-55 mm., as compared 

 with 45-49 mm. in the female. 



Immature birds of both sexes have the black mottling of 

 the back extending to and joining the black of the neck and 

 head, which are duller in colour than in the adult. 



A quite young male, specimen p, killed on the 6th Feb- 

 ruary, is attaining its first plumage ; the blackish feathers of 

 the head and throat, as well as the wing-coverts, are edged 

 with sandy-brown. 



Another immature male (No. 214) has attained the first 

 plumage_, but still retains some of the smoky-black, sandy- 

 edged feathers on the crown, throat, and wing-coverts. 



The fully adult plumage appears to be assumed at the 

 second moult. 



"The Pied Piping-Crow is by far the commoner o£ the two 

 species of Cracticus in the Mimika district. It was generally 

 observed in small parties in the tops of tall trees, and was 

 apparently feeding on berries, etc. It has aloud call and is 

 very crow-like in many of its actions,"— C II. B. G.
