the breast and flanks are generally broader and with more 

 tawny marks. As compared with A. a. arvensis and A. a. 

 cantarella, they have longer bills and much darker upper 

 parts^ and are dull white on the underparts without the 

 huffish tinge o£ A. a. arvensis. The measurements are as

Type. ^. May 29, 1920, Bom Jesus, Braga. In my 

 collection. 



Named in honour of Mr. William C. Tait, of Oporto. 



Dr. Hartert, who has very kindly examined the whole 

 series of these Skylarks, confirms my conclusions. 



I also have to exhibit four male Pied Flycatchers, which 

 we found breeding on May 7, 1920, at Manteigas, in a little 

 valley at the southern foot of the Serra da Estrella. Tiiis 

 bird was not previously known to breed in Portugal and 

 must be very local. I was surprised to find that these birds 

 belonged to the north- African form Aluscicapa hjpoleuca 

 speculigera. The Pied Flycatcher is not known to breed to 

 the south of the TagU'<, in the Peninsula, but it appears 

 to be so local that it might very easily be overlooked. One 

 specimen by its brownish wings is evidently a first summer 

 bird, and it is interesting to note that in this the white is 

 absent from the 3rd to 5th primaries and the outer tail- 

 feathers are edged with white, so that the wings and tidl, 

 which are part of the unmoulted juvenile plum;ige, are like 

 those of the typical form, while the white forehead-spot is 

 large, as in speculigera. 



We also found the Common Redstart breeding, a pair 

 here and there between Oporto and the Tagus. This bird 

 was also previously not known to breed in Portugal. Two 

 males which I obtained, one at Manteigas and one at
