and Parus a.vieirce), the Blue Tit, (^rested Tit, and Nntliatch 

 were unlike the Fortuguese forms and like tlio.se found in 

 the Pyrenees and northwards (viz. Parus c. ca>ruleus, P.,c. 

 rtikratiis, and SiLta e. ccesia). 



The Long-tailed Tit, of which he had collected a good 

 series, he had compared with series from Portugal as well as 

 the Pyrenees, and considered them to be all the same. 

 These birds must, therefore, be called yEgithalos c. taiti, and 

 yE. c. pyrenaicus must be considered as a synonym. In this 

 Dr. Hartert has concurred. 



The distribution of subspecies in the Peninsula was very 

 interesting and, so far as our present knowledge went, very 

 j)uzzling. One of the most interesting problems was pre- 

 sented by the Dipper. Mr. Witherby had obtained a large 

 series, and these differed in no way from the Scandinavian 

 Cinclus c. cinclus. Yet, in the Pyrenees there was a similar 

 but distinctly paler form (C c. pyrenaicus), while in France, 

 Germany, and Belgium there was a distinct form with much 

 more chestnut on the belly (C. c. aquaticus). 



This re-occurrence of Cinclus c. cinclus in north Spain 

 (probably also with Portugal) was made more extraordinary 

 by the fact that in south Spain, judging by the few speci- 

 mens available, a form occurred which was indistinguishable 

 from C. c. aquaticus. 



Mr. Witherby had found the Marsh-Tit fairly common 

 and collected a good series. With the exception of one 

 young bird collected by himself in 1919 in the Spanish 

 Pyrenees, no Marsh-Tit from Spain had been available 

 hitherto for examination. 



Comparison of this series shows that they were indistin- 

 guishable from Parus palusiris communis, and Mr. Witherby 

 was of opinion that Parus p. longirostris was not separable 

 from that form when a good series was compared. 



The Middle-spotted Woodpecker, not known from any 

 other part of Spain, nor indeed nearer than the Alps, was 

 found to be fairly common, and a series of eight was collected. 

 As these differed from other forms of the bird, Mr. Witherby 

 proposed to distinguish them as follows : —
