and plains, and appears to depart between March and June. It has a powerful flight, 

 and whirls in a whistling stream round the highest peaks of the rocks, and sometimes, 

 like its allies, utters a piping, melancholy, and yet somewhat sweet-sounding note. It 

 is in motion all day, and we have never seen it settle on trees or rocks." 



Mr. W. T. Blanford procured a specimen at Undel Wells in April, but states that 

 it was only seen by him at low or moderate elevations, and he does not recollect to have 

 ever noticed it on the tableland. Brehm believes that he saw this Swallow at Mensa, 

 in the Bogos country, in April, but Von Heuglin suggests that Hirundo senegalensis 

 may have been the species actually observed. During his last expedition to Shoa, the 

 late Marquis Antinori procured the present species at Denz, Let-Marafia, and Mahal- 

 Uonz. It was very common near the latter village from April to September, nesting in 

 June and August on rocks. 



Dr. de Bochebrune states that it is rare in Senegambia and was found at the following 

 places — Kita, Bakel, Fonta-Koro, Gangaran, Bakoy, and Baling ; he also says that it 

 inhabits Upper Senegambia, whence examples have been sent by Dr. Colin. The smaller 

 race, S. domicella, replaces it apparently in certain parts of Senegambia, the 

 localities mentioned by Dr. de Rochebrune being different for the two forms. 



Von Heuglin states that there is a specimen of the present bird in the Stuttgardt 

 Museum from South Africa, but there can be little doubt that the locality is erroneously 

 given. 



The figure in the Plate has been drawn from Mr. Blanford's specimen in the British 

 Museum, from which also the description has been taken.
