left; but even if we add tliosc noticed by Irby, the region is 

 not rich in species, and I think tliis may be accounted for 

 by a sameness in tlie character of the country. Among the 

 summer birds mentioned by Irby the Willow -Warlder and 

 Red-backed Shrike, recorded as conmion, should be noted, as 

 it seems doubtful if either o£ these breeds farther south in 

 the Peninsula. 



The chief interest in our collection lies in the geographical 

 forms of the resident species. The distribution of geogra- 

 2)hical forms in the Iberian Peninsula presents a problem 

 which appears at present very complex, but this may be due 

 to the scanty knowledge we still possess of the subspecies 

 occurring in various parts of Spain. A delightful collecting 

 tour in northern Portugal in 1920, in company with Mr. 

 W. C. Tait, the veteran ornithologist of Oporto, supple- 

 mented by many skins sent to me from time to time during 

 the last eight years by Mr. Tait, has given me material to 

 determine the subspecies resident in Portugal from the 

 Tagus northwards. Recently Surgeon-Admiral Stenhouse 

 has published an excellent paper (Ibis, 1921, pp. 573-59-4) on 

 a collection made b}' him in the neighbourhood of Algeciras, 

 and by his kindness I was privileged to compare these birds 

 and others collected by Captain Lyues with those from 



Pij)'e)ices.
