the Garden Warbler, while in Latham's description the l)ird 

 is said not to occur in England. What is beyond doubt, 

 however, is that Si/lvlu passerimi, as reported from the 

 Canary Islands, refers to the Diale of Si/lvia coiis/jici/iata 

 bella, the Canarian race of the Spectacled Warbler. 



Godman in his list of Migratory Birds of the Canaries and 

 Madeira (Ibis, 1872, p. 175) transfers »S'. passerhia Temm., 

 as used by Webb & Berthelot and Bollc, to the Subalpine 

 Warbler (^Sijlvia subalpina Temm.) without any apparent 

 justification. 



Hypolais polyglotta. Melodious Warbler. 



Mompo is the first author to note this bird (Catalogo de 

 liis Aves de Tenerife, 1876, \^. 247), and says " it builds its 

 nests in the vines .... is a resident and very common.'' 

 lie must surely have confused it with the Chiffchaft'. 



Cabrera includes Hypolais polyglotta Vieili. (Catalogo, 

 1893, [). 42) on the authority of Mompo. 



The Melodious Warbler occurs in Alorocco, ranging to 

 the llio de Oro and extending as far south as Senegambia. 

 Its presence in the Canaries as a rare visitor might therefore 

 be expected. 



Tardus viscivorus. .Missel Thrush. 



Busto is responsible for the inclusion of this species. It 

 figures in his list (Topografia mediea, 1864, p. 103) under 

 the name of Meriila viscivurus. 



Cabrera mentions it in his list ((Jatalogo, 1893, p. 4G) . 



If any Thrush visited the Canaries it would probably 

 belong to the north-west African race T. v. deichleri. The 

 typical form does not winter south of the Mediterranean 

 countries. 



Hylocichla ustulata swainsoni. Swaiuson's Thrush. 



Polatzek (Orn. Jahrb. 1909, |). 125) mentions Tardus 

 sivainsoni Cab. on the authority of Busto, Avithout any 

 apparent justitication. 



Although Busto is apparently responsible for the inclusion 

 of tiiis species, I cannot find the bird mentioned in Busto's
