Columbidie of the ^th'wpian Region. 269 



Very similar to T. australis, but a smaller birdj with a 

 bare forehead ; has a broad leaden-grey collar at the base of 

 the hiud neck ; the vinous patch on the wings is slightly 

 larger^ extending over nearly the whole of the least series of 

 wing-coverts ; the yellowish-buff partial edges to some of the 

 wing- feathers narrower ; tail grey, occasionally very narrowly 

 washed with greenish yellow at the edges of the feathers ; 

 the entire underparts agree well with T. auslralis, with the 

 exception of the thighs, which are uniform bright yellow, not 

 mottled with black ; iris blue, surrounded by a red rim ; bill 

 bluish grey, with the basal portion red ; feet yellowish flesh- 

 colour. Total length 10*5 inches, culmen from the frontal 

 feathers 0*95, wing 6-1, tail 3' 7, tarsus 0*9. 



Hab. West Africa from Senegal to Ondonga in Damara 

 Land, and in East Africa from about 16° N. lat. to the 

 equator. 



I have failed to detect any character for the separation of 

 T. nudirostris and T. crassirostris from T. calva. The so- 

 called T. nudirostris collected by Von der Decken at Mombas 

 probably belongs to T. umkefieldi, but I have not examined 

 the specimens. 



My description is taken from a Gold-Coast specimen in 

 my own collection. I have also examined specimens of this 

 species from Abyssinia, Gaboon, R. Danger [Ansell), Ambriz 

 and Angola {Monteiro). Two of the specimens in the British 

 Museum have M. Verreaux^s labels with " Phalacrotreron 

 nudirostris" and " P. crassirostris" written on them.
