outer*.

We should have set this down as the beautiful little 
ground pigeon to which Le Vaillant has given the 
name of “ Tourterelle emeraudine had he not said 
that it was “ particularly distinguished for its Derg 
short and rounded tail,” the intermediate feathers 
of which have two black bands on a grey ground. 
Now this is either erroneous or is applicable to a 
different species. The tail of our Senegal bird is 
very broad and rather long for its size, and the in- 
termediate feathers of the tail have no black bands 
* In crifthrophnjs this proportion is almost reversed, or at 
least the inner toe is not even equal to the outer.
