• cJiflii'SiCtGrs 



which varies in length from 3-0 to 3-2 inch. The tarsus of the South-African Stone- 

 Curlew {(E. capensis) varies in adult birds from 3'7 to 4*2 inch. An example of young 

 in first plumage of the latter species in the British Museum, collected by Dr. Smith at 

 the Cape, measures 3' 3 5 inch in length of tarsus. 



Riippell's Stone-Curlew is a local race of the South-African Stone-Curlew, and is a 

 resident in the Bogos Country, Kordofan, the south-western shores of the Red Sea 

 (Heuglin, Ibis, 1859, p. 344), Abyssinia, and Somali-Iiand (Speke, Ibis, 1860, p. 248). 

 It is described as frequenting the coast and the sandy plains, not ascending the mountains 

 quite as far as 3000 feet.
