the greater safety of the eggs, and that in many other cases 

 where an open nest is used the female, before leaving the 

 nest, covers the eggs. 



Another article of considerable interest is that of Miss 

 Annie Jackson on the moults of the British Ducks. She 

 again insists on the impossibility of " repigraentation " of 

 feathers and that all changes of colour are due to either 

 moult or wear. She also finds that the female surface- 

 feeding Ducks have a complete body-moult in spring and 

 that the underlying down is also shed and a new special 

 down acquired. In the male birds the spring moult is most 

 unusual. These facts, if not altogether new, are but little 

 known, and Miss Jackson's account of the moult is a valuable 

 contribution to our knoAvledge of the subject. 



As many as six new forms are added to the British list 

 in the present volume. These are Lusciniola melanupogon, 

 Hypolais pallida, (Enayithe leucura syenitica, Puffinus assi- 

 milis boydi, Puffinus kuhlii borealis^ and Tringa incana. All 

 have been taken at or near Hastings in Sussex, whence 

 come an unfailing supply of novelties, due to the energetic 

 researches of Messrs. Ford-Lindsay, Parkin, and Nichols. 



Mr. Witherby's papers on the moult of British Passeres 

 and on the * British Birds ' marking-scheme have already 

 been noticed in our pages, but an interesting note of his in 

 the April number informs us of a third example of a Swallow 

 marked in England being taken in South Africa. In this case 

 the bird was ringed at Lytham in Lancashire on July 3, 1915, 

 and was picked up dead near Grahamstown in the Cape 

 Province on February 6, 1916, by Mr. S. G-. Amm.

The last completed volume of ' The Emu ' contains a great 

 deal of interesting matter, and in the present short notice 

 we can only mention a few of the more important articles.
