•V;i Dr. R. B. Sharpe on Birds 



For some reason or another. Seebohm restricted the range of 

 this species to Damara-land and Benguela, but the Chat from 

 that country must bear the name of 8. aquatorialis, so far as 

 I can see. It is also S. albipileata of Bocage. It is the bird 

 figured by Blanford and Dresser under the name S. leuco- 

 mehena (P. Z. S. 187-1, pi. xxxvii. figs. 1 & 2 ), but S.griseiceps 

 of the same authors is identical with the true S. monticola, 

 of which it is the adult stage. 



Saxicola diluta of Blanford and Dresser holds the same 

 position with regard to S. aquatorialis as S. castor holds to 

 S. monticola. 



On the subject of these Chats the reader should consult 

 Finsch, Notes Leyden Museum, xxii. pp. 153-156 (1900). 

 Until we get an adult male moulting from the black-hacked 

 stage (S. monticola or S. leucomelcena) into the grey stage 

 (S. castor or 8. diluta) I feel inclined to admit that there are 

 four species of these Chats in South Africa. 



[Found throughout the year and very common, both on 

 the kopjes and the veldt. It was always seen singly or in 

 pairs, never in flocks. Specimens were often taken in traps 

 baited with meat. The nest was built in the rocks on the 

 kopjes, also in holes in " sluit "-walls, and even in old block- 

 houses; three eggs Mere the usual number, but occasionally 

 four were met with. It did not live well in captivity.]
