North African forms Sylvia undata toni and Tardus merula 

 algirus, Dippers not distinguishable from Cinclus c. cinclus and 

 Azure-winged Magpies. The latter Mr. Witherby had found 

 to be quite distinct from the series in the Tring and British 

 Museums from the neighbourhood of Madrid, Seville, 

 Granada, and Malaga, but like one which had been sent to 

 him some time ago by Mr. W. C. Tait from near Lisbon. 

 These he proposed to distinguish as a new race, as follows : — 



" Cyanopica cyanus gili, subsp. no v. 



"■ Similar to C. c. cooki, but crown glossed with blue rather 

 than purple and rest of upper-parts much greyer and less 

 brown ; under-parts also with greyer and less brown tinge ; 

 in coloration thus resembling C. c. sivinhoei, but without the 

 long white tips to the central tail-feathers. Measurements : — 

 3(5", wing 134-136 mm.; tail 180-195; bill from nostril 

 16-5-17. 3 ? , wing 133-135 ; tail 175 ; bill 15-16. 



"Tyj^e cJ; near Candeleda, south-western corner of the 

 Province of Avila, at the southern foot of the Sierra de 

 Gredos, Oct. 29, 1922 ; in my collection. 



"Named in honour of Senor Don A. Gil Lletget, the Spanish 

 ornithologist, on whose estate the birds were collected. The 

 type of C. c. cooki is in the British Museum and is labelled 

 " Spain," and Bonaparte does not state more precisely the 

 locality in which Captain Cook collected the bird, but the 

 specimen figured by Gould in his ' Birds of Europe ' (vol. iii. 

 plate 217) is evidently the same as the type, as both the 

 figure and the type have pale tips to the central tail-feathers, 

 which are rarely jn'esent in this bird. In his text to plate 

 217, Gould states that the specimen figured was lent to him 

 by Captain Cook, who procured it near Madrid. Madrid 

 ■ must therefore be regarded as the restricted typical locality 

 for C. c. cooki, and I have examined a number of specimens 

 both in summer and winter plumage from that locality. 

 These are all markedly different from the bird now described.''
