562 Mr. B. Alexander — An Ornithological 



where the country is well wooded and impenetrable. It was 

 an adult male in full breeding-plumage, and by the size of 

 the organs it must have been breeding. 



Adult S • Total length (measured in flesh) 3'9 inches, 

 culmen 0*05, wing 2, tail 1"6. Iris black. 



11. Parus NIGER Vieill. 



Locally distributed, and found either in pairs or in small 

 parties threading their way through the undergrowth. We 

 procured a good series. The plumage of the males shot in 

 August was very fresh, the feathers of the wings, under tail- 

 coverts, and tail being conspicuously edged with white, while 

 in those obtained near the Kafue river in January the white 

 edgings, especially on the primaries, under tail-coverts, and 

 tail, had almost disappeared. 



Adult ^ (Kafue river). Total length (measured in flesh) 

 6 inches, wing 3"25, tail 3"1. Iris black; legs and feet 

 lead-colour. 



Adult ? . Total length (measured in flesh) 5" 7 inches, 

 wing 3, tail 2-94. 



12. Parisoma plumbeum (Hartl.). 



One specimen obtained, and in the vicinity of the Kafue 

 river. 



Adult ? . Total length (measured in flesh) 5*5 inches, wing 

 2*62, tail 28. Iris hazel ; legs and feet slate ; upper man- 

 dible brownish black, lower horn- colour. 



13. MOTACILLA VIDUA SuudcV. 



Common along the river. The male possesses a pretty 

 song, which it gives out in a warbling fashion from the top of 

 rocks skirting the river. This handsome Wagtail is a fearless 

 bird. On one occasion we remember seeing an individual 

 running to and fro on the back of a huge crocodile that lay 

 basking on a sand-spit. On October 8 the young in their 

 brown plumage were abroad, while the adults had commenced 

 to moult. 



14. MoTACILLA FLAVA Linil. 



Considerable numbers of immature birds put in an ap- 

 pearance for the first time at Zurabo on December 10.
