These birds are undoubtedly identical with a series of 

 Larks collected by Alexander in northern Nigeria and near 

 Lake Chad. 



The subspecies is very close to the Indian M. c. cantillans, 

 but is rather paler. Following Zedlitz (J. f. 0. 1916, p. 59), 

 we believe that both these, as well as several of the African 

 races^ must be placed as subspecies of the South African 

 M. cheniana, the oldest name in the group.

In the J. f. O. 1916, p. 59, Count Zedlitz gives a list of 

 the races oi M. cheniana and includes M. albicauda among 

 them. This, however, we cannot accept, as we liave speci- 

 mens of M. albicauda in the Museum from throughout the 

 range of M. c. chadensis. Butler mentions that he found 

 them often in company with M. c. chadensis, and that they 

 were in breeding condition. Is it possible that M. albicauda
