MiRAPRA SABOTA Smith. 



Mirafra sabota Stark, i. p. 208 ; Shelley, iii. p. 36 ; Reich, 

 iii. p. 332. 



a,b. S- Lehutitu, 3000 ft., 15th & 19th May. (Nos. 

 39, 7?. B. IF., & 508, G. L.) 



Iris hazel or brown ; bill horn-coloured ; feet brown. 



The Sabota Lark w^as fairly common in the Kalahari and 

 Ngamiland. It perches a great deal upon bushes and in trees. 



Mirafra rufopilea (VieilL). 



Mirafra rufopilea Stark, i. p. 218 ; Shelley, iii. p. 46; 

 Reich, iii. p. 342. 



a. ^. Lehutitu, 3000 ft., 29th May. (No. 513, G. L.) 



Iris hazel ; bill black ; feet brown. 



This is a quite freshly-moulted example of M. rufopilea with 

 tlie general colour of the upper parts greyish ; the chestnut 

 and black-barred middles of the feathers are almost entirely 

 masked by the long greyish lateral fringes, which give a 

 lioary appearance to the plumage. The pale cinnamon 

 feathers of the breast and belly also have much paler 

 margins, giving the under parts a paler appearance. At first 

 sight this specimen appears so different from the specimens 

 of M. rvfopilea in the British Museum that it might easily 

 be mistaken for a desert form ; but I am satisfied that this 

 is not the case. 



This group of Larks is but sparsely represented in the 

 Kalahari or Ngamiland, as there is too much forest country 

 to suit their habits. 



Certhilauda kalahari/e, sp. n. 



? Certhilauda rvfula, Fleck (nee VieilL), J. f. O. 1894, 

 p. 411. 



Adult male. Most nearly allied to C. arenaria Reich, from 

 Great Namaqualand, but differs in having the general colour 

 of the upper parts (with the exception of the upper tail- 

 coverts, which are rufous) brown instead of rufous. Each 

 feather of the mantle and back is dark brown down the 

 shaft, paler brown towards the edge, and fringed on the sides 

 with pale isabelline, likewise tipped with white. Iris hazel ;
