A careful comparison of these Desert-Larks with those 

 in the British Museum convinces us that they are identical 

 with the form described by Shelley as A. samharensis from 

 Amba in the highlands of what is now Eritrea, the type of 

 which is in the Museum. 



Hartert considers this race identical with A. assabensis 

 Salv. from Asseb on the southern Abyssinian coast near the 

 straits of Beb el Mandeb, but we believe them to be quite 

 distinct, as we have examples in the Museum from Hensa 

 and Somadu in northern Somaliland, which were compared 

 with specimens of A. assabensis sent by Salvadori, and were 

 pronounced identical. These are very much darker than 

 the northern Abyssinian and Port Sudan birds. From 

 southern Somaliland comes A. d. akeleyi Elliot, quite a 

 distinct paler race.
