76 Mr. B. Alexander — An Ornithological 



little long-drawn cry, weak and mouse-like, while, when 

 excited, it will give out a series of notes, which might be 

 rendered by the syllables ''tiz, tiz, tiz,'' rapidly repeated. 

 We obtained a good series along the Zambesi, the first 

 specimen at Senna and the last near the Kafue river. 



In an immature specimen (Vate, Livhty stone) , which seems 

 to be referable to S. pallida, the superciliary stripes, sides of 

 face, and underparts are distinctly washed with pale rufous- 

 bufi', and the bill is light brown. 



83. Chlorodyta neglecta, sp. nov. 



Chlorodyta neglecta Alexander, Bull. B. O. C, x. p. xvii. 



It appears that this species has hitherto been overlooked. 

 It is the south-eastern representative of Chlorodyta flavida 

 (Strickl.), from which it differs in the following points : — 

 Feathers of the rump are uniform yellowish green, like the 

 back; throat, cheeks, and under tail-coverts silky white; 

 under wing-coverts white ; while the feathers of the thighs 

 are greyish white. The British Museum possesses adult 

 specimens from Kingwilliamstown, Elands Post, the Maka- 

 laka country, and from the Cheringoma district in Mozam- 

 bique. These correspond with our birds from the Zambesi. 



Of C. flavida there is also a good series, obtained from 

 T^orthern Damaralaud and the Ovaquenyama country lying 

 directly to the east of it. 



In both species some individuals have the head and nape 

 of an entirely slaty grey, others have only the forehead and 

 sinciput of that colour, while in several the sides of the crown 

 and of the nape show signs of becoming grey. In our adult 

 specimens of C. neglecta, freshly moulted and killed between 

 July and December, only the forehead and sinciput are grey. 

 On the other hand, a male shot in January has the whole 

 crown and nape of that colour, and from its worn plumage 

 it is evidently an old bird and had done breeding. The 

 grey on the head and nape, therefore, is a sign of age, and 

 is probably assumed after the second moult. 



The area of this species is South-eastern Africa, ranging 

 into Mozambique, while that of C. fl,avida is Northern 

 Damaralaud and the Ovaquenyama country.
