the year as the first (cf. Bull. B. O. C. vol. xiii. p. 51, 1903), 

 and also after prolonged south-westerly gales. The present 

 specimen was the third known to have occurred in Britain. 

 During the recent gales large numbers of sea-birds had 

 succumbed, and most of those found dead on the beach were 

 in very poor condition. 



Mr. Butterfield also referred to Count Salvadori's letter in 

 the current number of ' The Ibis' (1904, p. 166) in regard to 

 the species of (Estrelata occurring at Madeira and the Cape 

 Verde Islands and commonly assigned to CE. mollis. Count 

 Salvadori had clearly shown that this Petrel could be sepa- 

 rated from CE. mollis, and he had proposed for it the name 

 CEstrelata fea [Ann. Mus. Civ. Gen. (2) xx. p. 305 (1899)]. 

 Skins of the two forms were shown, and it was pointed out 

 that CE. fece differed conspicuously from CE. mollis in being 

 smaller and in the absence of the dark pectoral band, which 

 is always present to a greater or less extent in the latter 

 form. 



Mr. Ernst Hartert exhibited an example of a new 

 subspecies of Certhia brachydactyla, which he described as 

 follows : — 



Certhia brachydactyla Dorothea, n. subsp. 



This new form of Certhia possesses all the main features 

 of C. brachydactyla, — i. e. the dark patch on the under wing- 

 coverts just in front of the first primaries, the long bill, and 

 greyish upper surface. It differs from C. brachydactyla 

 brachydactyla in the much darker blackish-brown ground- 

 colour of the upper surface, the greyish-brown ; instead of 

 rusty-rufous, upper tail-coverts, the darker and more 

 brownish tail, and the constant absence of a pale fulvous 

 spot on the fourth primary, which is sometimes indicated 

 but generally absent in German examples of C. brachy- 

 dactyla. In lacking this fulvous spot it agrees with C. bra- 

 chydactyla harterti, from the Alum Dagh in Asia Minor, 

 which is, however, much more rufous brown, less blackish 

 on the upper surface, rufous on the lower rump and ujmer 

 tail-coverts, and reddish brown on the tail. 



C. brachydactyla dorothea inhabits the pine-forests of
