76. GrAUCALXJS CiERXJLEOGRISEUS (G. R. Gr.). 

 Graucalus ccsruleogriseus, Salvad. op. cit. vol. ii. p. 122. 



a. 2 ■ Mansinam. 



b. $ . Dorei. 



c. $ . Arfak. 



Iris brown ; bill and feet black. Length about 34-0 centims., 

 wing 16"0-16*6. The Mansinam example differs from the others 

 in having the apices of all the flight-feathers edged with white. All 

 the tail-feathers are also strongly tipped with white, the outer pair 

 for half an inch or more. In the Arfak bird there are no white tips 

 to the wing-feathers, and only a faint trace of that colour at the 

 apices of the two external rectrices, and the under wing-coverts are a 

 deeper isabelline. All three examples are darker on the under 

 surface than are those in the British Museum from the Aru Islands. 



77 . Graucalus boyeri (G. R. Gr.). 

 Graucalus boyeri, Salvad. op. cit. vol. ii. p. 124. 



a. 2 • My sol. 



Iris dark brown ; bill and feet black. Length 24*5 centims., 

 wing 12-8. 



Lores white, nasal plumes huffish ; no black on chin, the first two 

 or three feathers of which are pale buff. The external pair of rec- 

 trices are faintly tipped with grey. 



78. Graucalus magnirostris, Forsten. 



Graucalus magnirostris, Salvad. op. cit. vol. ii. p. 129. 



a. S • Waigiou. 



Iris dark brown ; bill and feet black. "Wing 1 7'2 centims., tail 

 16'0, bill 3-2, tarsus 27. This species has hitherto been considered 

 as pecuhar to the Halmaheira group, but a comparison of the present 

 example with individuals from that island and Batchian shows that 

 they are identical.
