This genus is very easily distinguished by its ear-tufts. 

 The only species of Lark from South Africa which I have not seen, 

 and consequently have been unable to include, is the following, 



Mirafra nigricans.

 p. 99. 



Mirafra nigricans, Gray Hand-1. ii. p. 121 (1870). 



The following is a translation of Professor Sundevall's original 

 description. 



Dusky blackish ; underneath white, the breast spotted with black ; 

 the orbits and elongated eyebrows white ; the stripes on the throat, 

 cheeks, and lores black. 8 inches long, wing 4-8, tarsus 125, 

 middle toe 0'75, with nail 0-9. Bill tolerably large for a Lark; 

 nostrils bare, with an arched membrane. Feet raised, as in most 

 African Larks ; all the claws short ; that of the hind toe less than 

 an inch, curved. Tail moderate, entirely black (in our specimens 

 injured). Quills black, the primaries invariably broadly fulvous. 

 Our male specimens, killed during moult, are varied above with 

 some feathers waved with pale rufous, the wing-coverts edged with 

 white. 



Hab. The district of the Limpopo in Upper Caffraria.
