VISCOUNT WALDEN ON THE BIRDS OF CELEBES. 77 
more arched and stouter, but it does not differ in form from that of S. torquata so 
much as the bill of 8. torqguata does from that of S. caledonica. In C. albertine, how- 
ever, the naked spaces, which are confined to the ophthalmic region in the Celebean 
birds, extend to under the throat. In it also the frontal plumes are not developed and 
curved back as in the two species of Streptocittw. Indeed the normal condition of the 
frontal or nasal plumes is the only external character in which Charitornis differs from 
Streptocitta. It seems more in accordance with the facts to regard the three species 
as belonging to the same natural genus, with S. caledonica as the connecting link. In 
the colouring of the plumage C. albertine only differs from S. caledonica by having the 
head white. By the black-and-yellow colouring of the bill, the South-Celebean species 
occupies an intermediate position between the completely black bill of S. torquata and 
the completely yellow bill of C. albertine. 
Mr. Wallace has led us to infer (Malay Archip. i. p. 430) that Charitornis is confined 
to Celebes; but this is doubtless an error. Professor Schlegel’s types were obtained 
in the island of Soula Mangouli; and the species has not been recorded from any other 
locality. 
I cannot concur with the Leyden Professor in placing Streptocitta among the Gracu- 
lide ; though a most anomalous form, its nearest affinities seem to be with the Corvide.

Prince Bonaparte’s description is so vague that it is impossible to decide whether he 
described from the Celebean or the Ceramese bird.

This is a well-marked species, most nearly allied to A. javanicus, Cab. (=Pastor 
griseus, Horsf., nec Wagl.), but readily distinguishable by the upper and lower 
plumage being light grey, and not dark iron-grey. All its dimensions are less; and 
it has the base of the mandible with traces of black, but not as marked as in its other 
congener, A. fuscus (Wagler), ap. Jerd., of continental Asia.
