312 Mr. D. A. Bannemnan on the [Ibis, 



wrote this to Tschusi, and hence Tschusi^s error in Orn. 

 Jahrb. 1903, p. 176, in referring these birds to (E. stapazina, 

 when, as pointed out by Polatzek (Orn. Jahrb. 1909, p. 125), 

 tliev really belong to a race of (Enanthe ckserti. 



In his paper, here referred to, Polatzek explains that 

 von Thanner wrote to him that the Wheatears described 

 [by Tschusi] in Orn. Jahrb. 1903, p. 176, were not 

 CE. stapazina but G^. deserti. 



Range. Tristram's Desert-Wheatear extends from Tunisia 

 to Cape Blanco. I have handled a skin in the Tring 

 Museum from the latter locality, obtained on the 10th of 

 May. 



Family Muscicapid.e.

 Type locality : France. 



The Spotted Flycatcher is probably a fairly regular Bird 

 of Passage in varying numbers during the spring and autumn 

 migration. 



It must be remembered that in the whole group of islands 

 there are probably not more than two ornithologists who 

 know the bird by sight, and that for years together a 

 bird so sombrely coloured as the Spotted Flycatcher might 

 entirely escape detection. 



Opinions vary as to the migrations of this Fh'^catcher to 

 the Canary Islands, as the following quotations show : — 



"An occasional straggler ; I saw one Spotted Flycatcher 

 that had been shot in the winter near Laguua^' (Meade- 

 Waldo, Ibis, 1889, p. 2; 1893, p. 192). 



"A regular bird of passage in the Eastern islands'' 

 (Polatzek, Orn. Jahrb. 1909, p. 123). 



"An accidental migrant arriving in these islands in May, 

 when I have shot various specimens at Laguna " (Cabrera, 

 Catdlogo, p. 48). 



* If Vroeg's Catalogue (1764) is recognized, the Spotted Flycatcher 

 must be Ijnown as M. striata striata. I follow tlie Committee of the 

 B. 0. U. List (1915, p. S71j in rejecting Vroeg's names.
