and tail-feathers, tliougli it has been stated that the spring 

 moult of the Pipits extends to the small feathers only. 

 This is the case with many other birds, espeeially amx)ng 

 the Waders, many of which were found to be moulting in 

 November or earlier, soon after their arrival in southern 

 latitudes. Dr. Claude Ticehurst also writes on the same 

 subject in reference to a previous paper by Miss Baxter and 

 Miss Rintoul, confirming and adding to their observations 

 on the migration of birds from Great Britain in moult. 



Another contribution by the same two ladies gives us a 

 list of the continental racial forms of various British birds 

 which migrate through, or winter in^ our islands ; they 

 mention some of the more distinctive characters of these 

 races and give instances of their occurrence. We notice that 

 they continue to insist on the possibility of distinguishing 

 the Continental and British races of the Gold-crest and 

 Iledge-Sparrow, in contradistinction to the views put 

 forward in the new B. O*. U. List of British Birds. 



The July-August number of the magazine is entirely 

 devoted to the " Report on Scottish Ornithology in 1915," 

 by the same two ladies^ a most valuable summary of work 

 done in Scotland. Though the writers were hampered by 

 military restrictions and the absence of many observers, 

 their report contains many items of interest such as 

 the wintering of the continental race of the Great Tit in 

 Scotland, but most of the new recoi'ds have already been 

 published elsewhere. Summaries are given of ringing 

 results, plumage variation, habits and food, migration, 

 including a summary of weather conditions and notes on 

 movements arianged under species. 



The Editor, Mr. Eagle Clarke, records the occurrence of 

 the British Tree-Creeper in the island of Lewis, a place 

 entirely unsuitable to its habits owing to the absence of 

 trees. The bird was evidently blown over from the main- 

 land by a severe storm. Another interesting record is that 

 of the Continental Barn-Owl taken on Unst, Shetland. 

 No Barn-Owl has previously been recorded from Shetland, 

 and the continental form Flammea flammea guttata was not
