318 Dr. J. Kirk on the Birds of the Zambesi Region. 



19. Campicola pileata. 



Among the rocks of the Murchison Rapids, common ; in other 

 situations not observed, 



20. Crateropuius plebeius. 



Common in long grass near rivers. Found in flocks of five or 

 six. A noisy bird in the reeds, but a fine songster when perched 

 on the Borassus-palms in the early mornings during the rainy 

 season. 



21. Motacilla VIDUA. Native name, " Droindwi." 

 Everywhere. Never injured by the natives, who have some 



superstitious belief connected with it. 



22. Macronyx croceus. 



Abundant on the sea-coast of the delta. Probably the same 

 as that found in the interior. Seems to feed on the berries of 

 the Cassytha, a creeping parasitic plant. 



Fam. PYCNONOTIDiE. 



23. PycNONOTUs nigricans. 



One of the commonest birds in the country. A good songster, 

 but not equal to Crateropus plebeius. 



Fam. ORIOLIDiE. 



24. Oriolus, sp.* 



Found near Tete, on the Shire, and in the Delta. Plumage 

 varies considerably, according to season. 



Fam. LANIID^. 



25. Enneoctonus collurio. 

 Shupanga. Shire. 



26. Laniarius, sp. nov. 



Common near Tete, where many specimens were obtained. 

 It is near to L. bulbul, but differs in being rather larger, and in 

 having at the end of the tail-feathers a central white spot. 



Specimens are in the British Museum.
