 outer*.

WE should have set this down as the beautiful little 

 ground pigeon to which Le Yaillant has given the 

 name of " Tourterelle emeraudine" had he not said 

 that it was u particularly distinguished for its very 

 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 erytJirophrys this proportion is almost reversed, or at 

 least the inner toe is not even equal to the outer.
