Distribution. — From the valley of the Orange Eiver and Natal 

 northwards throughout Bechuanaland, the Transvaal, Rhodesia, 

 and German south-west Africa, but everywhere a somewhat 

 scarce bird. North of the Zambesi it occurs in Angola, Nyasa- 

 land, and German oast Africa, but is replaced in west and north- 

 east Africa by another though closely allied species. 



The following are localities : Cape Colony — Upington on the 

 Orange River (Bradshaw), Colesberg (Ortlepp) ; Natal (British 

 Museum) ; Transvaal — Potchefstroom (Ayres) ; Bechuanaland — - 

 Bamangwato (Holub), Lake Ngami (Chapman) ; Rhodesia — Panda- 

 matenka, near Victoria Falls (Oates), Salisbury (Marshall), Ft. 

 Chiquaqua (Sowerby) ; German south-west Africa — Otjimbinque 

 (Andersson), Omaruru (Eriksson). 



Habits. — The Swallow-tailed Bee-Eater is a resident bird in 

 most of the localities where it occurs, though Andersson found 

 it more numerous in Damaraland in the rainy season. 



Everyone remarks it as a rare bird, generally seen singly or in 

 pairs. Unlike other Bee-Eaters it is often found far away from 

 water, generally perched on low trees or bushes in open spaces in 

 forest. As is the case with all this group of birds the food con- 

 sists of insects of various kinds, blue-bottles, grasshoppers, and 

 hymenoptera have been noted ; these are usually caught on the 

 wing, though sometimes taken from leaves and flowers. These Bee- 

 Eaters hawk over trees in search of their prey, but do not fly so high 

 as other species. 



The only observations on the nesting habits of this species are 

 by Andersson, he found a nest on the Omaruru river on October 31. 

 It was at the end of a horizontal passage, about three feet long, in
