Distribution. — This is a tropical African Plover, which has but 

 seldom occurred south of the Zambesi. It is stated to have been 

 obtained by Verreaux on the Buffalo Eiver in Namaqualand, but 

 possibly this is an error. It is found all over West and Bast Africa, 

 from Liberia and Kordofan southwards. 



The following are localities : Transvaal— Potchefstroom (Ayres) ; 

 Rhodesia — near Victoria Falls (Holub) ; Portuguese East Africa — 

 Senna, July, and Tete, August (Alexander), Urema Eiver in the 

 Beira district, October (S. A. Mus.) 



ifaSite.— Captain Alexander gives the following account : " This 

 bird is found in pairs here and there along the river, haunting the 

 margin of the water where the banks are gently sloping and of a 

 sandy nature. At one's approach they jump up in a spasmodic 

 manner to fly out across the water. When startled they are noisy 

 birds, uttering their plaintive but not unmusical ' whit whit,' repeated 

 rapidly in succession. They are often found at some distance from 

 water, haunting the sandy stretches of a dried-up river bed or moist 

 spots where the grass is short and succulent. In such places a 

 small party may regularly be observed towards evening fully occu- 

 pied in ' drawing ' worms. The flight of this species is strong and 

 buoyant, with a steady beat of wings. At dusk these Plovers often 

 become noisy, giving vent to plaintive ' whits.' " 



Mr. Ayres' only specimen was shot in a garden in Potchefstroom 

 and was subsequently unfortunately lost. 



Mr. Millar found this bird abundant along the Pungwe and 

 Dingi-dingi Eivers in the Beira district in October. He readily 

 recognised them when in flight by the patch on the wing. A pair 

 were evidently nesting or had young along the river in the shingle, 

 but he was unable to find the nest. Subsequently he shot and
