Ad. ? . Basupu, Oct. 30, 1902. 



Iris blue ; bill bluish horn-coloured, soft parts crimson ; 

 legs and feet orange-yellow. 



A common Pigeon in the vicinity of cultivation. The 

 typical V. calva is found in Loango and Angola. Our two 

 specimens from Fernando Po agree well with the Angola 

 specimens in the British Museum and with those from 

 Cameroon and Gaboon. On the other hand, specimens 

 from Sierra Leone and the Gold Coast differ from the typical 

 V. calva in having the grey neck and collar brighter and 

 more distinct, and the under parts of a pale greenish olive 

 instead of yellowish greenish olive. This form is the Vinago 

 calva sharpii of Reiclienow (Orn. Mouatsb. 1902, p. 15).
