550 Mr. M. J. NicoU on the Subspecies of 



rostris, but with a sufficient series of each form the differences 

 are quite appreciable. 



I have not yet seen a true specimen of G. c. mceritica 

 from outside of the Fayum, and I believe this race to be 

 restricted to that oasis. 



Wing-measurement of males ranges from 101-108 mm. 



Galerida cristata caroli Hartert. 



Galerida cristata caroli Hartert, Vog. pal. Fauua, i. 1904, 

 p. 231. 



This, the palest of all the Egyptian Crested Larks, was 

 described from specimens collected by the Hon. N. Charles 

 Rothschild in the Wadi Natron in Lower Egypt. 



Outside the Wadi Natron the distribution of this form is 

 somewhat erratic. The extreme western limit of its range 

 is uujinown, but I have specimens from Dabaa, 160 miles 

 west of Alexandria on the Mediterranean coast, collected 

 by T. W. Russell Bey and Mr. T. E. S. Armstrong. 



On the islands in Lake Mareotis it breeds and, as we 

 have pointed out, it interbreeds there with G. c. ahirostris. 

 On the promontory of Abu Kir, near Alexandria, it occurs 

 as a breeding species, and there it appears to form a small 

 isolated colony on the sandy ground close to the sea. In 

 June 1913 it was the only form of Galerida I found there, 

 though at Montaza, a few minutes train journey south of 

 Abu Kir, I found G. c. altirostris abundant, and the latter 

 was extremely common immediately to the east and along 

 the north shore of Lake Edku, where it was feeding young. 



On the east G. c. caroli breeds on the shore of Lake 

 Menzaleh, near the Suez Canal, and Capt. H. Lynes found 

 it near Mahsameh between Ismailia and Cairo (Ibis, 1912, 

 p. 134), and I obtained a straggler at Inchas, within the 

 range of G. c. nigricans, on 13 Feb. 1911, after a gale from 

 the north. 



A series of four examples from Dabaa collected in January, 

 February, and March, are paler on the upper side than most 

 of those from the Wadi Natron collected in March, but I 

 have specimeus from the latter typical locality which exactly 

 match them.
