At the time of my visit to Lanzarote I was not aware 

 that Dr. Hartert had separated and named the Lanzarote 

 ChifiFchaff. On comparing the examples obtained with my 

 specimens from Gran Canaria of P. c. canariensis, T was at 

 once struck witli the difference which existed in colour 

 between these two island forms. The wing formula, 

 however, appears to be similar to that of P. c. canariensis. 



Dr. Hartert has kindly sent me a small series of this 

 Chiffchaif from the Tring Museum. It is distinguished 

 from P. c. canariensis by its somewhat smaller size, some- 

 what lighter, less olive-brown upperside, and less red, more 

 fawn-yellow underside. The under wing-coverts are a paler 

 shade of yellow. 



The Lanzarote Chiffchaff was not met with until we 

 reached the valley of Haria, where, however, only three or 

 four birds were heard. They are resident in this district 

 throughout the year according to Polatzek, who took two 

 nests. This ornithologist, who spent a considerable time in 

 Lanzarote, found them much more plentiful in the Haria 

 district than I did myself; he also discovered them at Mai 

 Pais. 



This Chiffchaff has not yet been found in Fuerteventura 

 or in any of the smaller islets. 



Examples were obtained from Lanzarote. 



Bill dark horn-colour ; iris dark hazel ; legs and feet 

 very dark brown in one specimen, greenish brown in the 

 other, soles yellow.
