A collection sent to me by Dr. Kirk from the Usambara 
mountains contaimed three specimens of this new species, 
a male and two females. Compared with the well-known 
A.morio (Linn.) of South Africa, the present species is much 
smaller, being only about two thirds of the size; the bill is 
proportionately shorter and stouter, and the head, neck, 
and wings are greener. ‘The sexes differ in a similar 
manner. 
I have named this species after my friend Mr. Gerald
