There is scarcely a more beautiful little bird among 
the smaller species of this family than the one now 
before us. It seems to have a unde dispersion on 
the African continent, being found at the Cape of 
Good Hope, Senegal, and as far as Nubia * ; but 
whether it is in any degree migratory like the two 
more typical species of Ectopiste), is very uncertain. 
Mr. Selby very judiciously considers this as a dis- 
tinct type from the sub-genus Edopistes of the Ame- 
rican continent, of which, however, it seems to be 
the representative. It does not appear that the sub- 
genera of the typical pigeons are characterised by 
that peculiarity of geographic distribution which so 
frequently separates the birds of the old from those 
of the new world ; at least we have not yet been 
able to detect any marked difference in structure
