This specimen is probably not fully adult. Its identification 

 rests on the description given by Reichenow (Vogel Afrikas, I., p. 552) . 

 Its bill and foot agree with Neumann's drawings of these parts of 

 tachiro in Journal fur Ornithologie, 1889, p. 41, and not with his draw- 

 ings of sparsimfasciatus.
