the under surface nearly pure white, near the Farmingtou 

 River, on July 2^ and August 9^^. 



The dark slaty brown upper surface will readily dis- 

 tinguish our five (with the two of my first journey) 

 specimens from those from southern and eastern Africa, 

 and even from those from the Gold Coast. A young female, 

 all over spotted underneath , except the throat , which has 

 a central longitudinal streak of brown, and the under 

 tail-coverts , which are pure white , I received as a nestling 

 and kept it alive for about six weeks. This specimen had 

 the iris bluish grey, and the thighs begin already to get 

 a rufous tinge. It died on the IQth of February. 



The above cited full-grown female from the Du Queah 

 has the under surface also strongly spotted and the 

 throut striped , but the under tail-coverts are spotted like 

 the rest of the lower surface, which latter has a slight 

 fulvous hue, and the thighs are strongly tinged with ru- 

 fous. Both male and female from the Farmingtou R. have 

 the whole lower surface pure white, with the exception of 

 the spotted sides of chest and the flanks , which are broadly 

 barred with dark brown. The thighs of the male are very, 

 those of the female less strongly tinged with rufous.
