VISCOUNT WALDEN ON THE BIEDS 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 S. torquata does from that of S. caledonica. In C. albertincp, 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 Streptocittce. Indeed the normal condition of the 

 frontal or nasal plumes is the only external character in which Charifornis differs from 

 Streptocitta. It seems more in accordance with the facts to regard the three species 

 as belonging to the same natural genus, vrith S. caledonica as the connecting link. In 

 the colouring of the plumage C. alhertince 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. albertime. 



Mr. Wallace has led us to infer (Malay Archip. i. p. 430) that Charitomis 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- 

 lidffi ; though a most anomalous form, its nearest affinities seem to be with the Corvidee.

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 weU-marked species, most nearly allied to A.javanicus, Cab. {= Pastor 

 griseus, Horsf., nee 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.
