there are several interesting variations in its struc-

Saxicola, uniting that genus to the group we have

Total length, 5 J inches ; hill, from the gape, T " 0 ; 
from the front, T 5 5 ; wings, 3 ; tail beyond, 1 ; from 
the base, 2 T ] 5 ; tarsus, T s 3 ; middle toe and claw, j'-q.

sexes arrived from Senegal. It was this species,
