276 MOTACILLA LONGICAUDA. 



was struck with their particularly graceful movements as they 

 glided over the stones in search of insects, their favourite food 

 being a soft small dragon-fly, and further remarks that they 

 warble very prettily though not loudly. According to Stark : 

 '' This peculiarly beautiful and graceful Wagtail is not un- 

 common on such of the rocky streams of Natal and Zululand 

 as are broken by numerous rapids and waterfalls, and I have 

 myself never met with it elsewhere. Unless the young have 

 lately left the nest, seldom more than a pair are seen together, 

 and these monopolise a certain range of stream, which they 

 appear never to leave. In their habits they closely resemble 

 the Grey Wagtail of Europe. A newly completed nest, found 

 near Pinetown in Natal on August 5, was built on the ledge 

 of a rock by the side of a waterfall ; it was rather bulky, con- 

 structed outwardly of dead leaves, moss and dry grass, the 

 cup-shaped hollow lined with fine rootlets and hair." 



To the north of the Zambesi these Wagtails are distributed 

 over the Shire highlands and along the streams which flow 

 from the mountains into Lake Nyasa, for Mr. Wkyte has 

 collected specimens on the Milanji plateau, along the Mtondwe 

 river, at Zomba and at Kombi on the Masuku mountains at 

 7,000 feet. 



All that I can find regarding its occurrence in German 

 East Africa is that Sir John Kirk sent me a specimen from 

 Ugogo, which is now in the British Museum, and that Sir 

 Harry Johnston collected two specimens on Kilimanjaro at an 

 elevation of 6,000 feet, so it is strange to note the absence of 

 this species in the large collections made by Bohm, Fischer, 

 Emin, Mr. Jackson and Dr. Ragazzi. 



Antinori sent five specimens from Shoa collected in May, 

 June and August, and in Abyssinia Riippell discovered the 

 type of the species in the Semien district. Von Heuglin met 

 with it in the provinces of Adet and Telent and along the
