Gaboon bird 4'7, and the Fantee and Senegal specimens 4 - 5-4 - 6. The South-African 

 specimens are rather paler under the wing, on the under wing-coverts and axillaries, but 

 even in this respect they only differ to a slight extent from H. gordoni. 



But little has been recorded of the habits and nidification of this species. It was 

 discovered by the late Prof. Wahlberg in Natal, and was afterwards obtained by Mr. T. 

 Ayres in the Transvaal, where, however, it is scarce. It appears near Potchefstroom in 

 the spring of the year, in September, and remains throughout the summer. It was found 

 by Mr. Ayres to be " much more plentiful in the warmer Rustenberg district than in the 

 open and colder country around Potchefstroom." A specimen in the British Museum 

 was obtained by Mr. F. A. Barratt between Pretoria and Lydenburg ; and the late 

 Mr. Prank Oates met with the species at Tati in the Matabili country in October, and 

 further north at Inchlangin in December. It was seen during Mr. Jameson's expedition 

 by Mr. Ayres in the Mashoona country in September, October, and December. 



Mr. T. Ayres found the nest of the present species in an old brick-kiln on the 

 outskirts of the village of Rustenberg, and he says that it much resembled that of 

 JS. cucullata. Mr. Prank Oates found many small beetles in the stomach of one which 

 lie shot at Inchlangin. 



The figure in the Plate has been drawn from a specimen in Capt. Shelley's collec- 

 tion, the description being copied from the British-Museum ' Catalogue.'
