a 
272 LANIUS LEUCOPYGOS 
This species was founded by Swainson on a Shrike 
presented to the British Museum, by the Hudson Bay Co., 
presumed to have been obtained in their territory in North 
America. It is, however, no doubt identical with a form of 
LL. excubitor common in North Africa from Tunis to Egypt, 
where Mr. Michael Nicoll has found it breeding in several 
localities, and has traced it as far south as Luxor. 
Mr. Nicoll further informs me that he has examined the 
Shrikes found breeding by Butler near Port Sudan on the Red 
Sea coast, and that they are undoubtedly examples of this 
species, which must therefore be included in the fauna of 
the Ethiopian region as defined for the purpose of this work. 
Butler writes that he found this species common at Suakim 
in March, 1906. 'T'wo years later he noticed the same Shrikes 
daily throughout the month of May at Khor Arbat, a spot 
about 25 miles inland from Port Sudan, and on the 16th 
found a nest containing four young, placed about 4 ft. from 
the ground in a “ Marakh” bush (Leptadenia spartium).
