quieter conditions in the North Sea, where the food-supply 

 and other matters are quite different ; finally they are driven, 

 on to the coast and inland, enfeebled for want of food, as 

 those picked up have almost invariably empty stomachs. 

 Such is Dr. Lowe's interpretation of the " wreck of the Little 

 Auk." 



Some contributions from other authors have been included 

 in this volume. Mr. Bentley Beetham writes a chapter on 

 the flight of birds, Messrs. W. P. Pycraft and W. R. Ogilvie- 

 Grant each treat of the Cormorant. Mr. A. J. R. Roberts 

 sends an account of the breeding-place of the Skua on the 

 island of Foula, and Mr. C. J. King describes a night spent 

 by him on Annet Island in the Scillies, where the Manx 

 Shearwaters nest. 



Altogether it is an unusual work both as regards its letter- 

 press and illustrations, most of which have appeared in 

 ' Country Life,^ and therefore need no further commendation.

[Descriptions of ten new African Birds of the Genera Pogonocichla, 

 Cossypha, Bradypterus, Sylvietta, MelantparuSj and Zosterops, by Edgar 



A. Mearns. Smiths. Miscell. Coll. vol. 61, no, 20, 1913, pp. l-s!] 



The title of this paper sufficiently indicates its contents. 

 All the new forms are described as subspecies, and all are 

 from British East Africa and Abyssinia, and have been 

 obtained by the many recent expeditions to Africa from the 

 United States, including that of Dr. W. L. Abbott, which 

 took place so long ago as 1888. 



Nicoll on the Egg of the Sudan Crowned Crane. 



[Some Notes on the Eggs of the Sudan Crowned Crane, Balearica 

 pavoiima cecilics. By Michael J. Nicoll. Cairo Scientitic Journ. vii. 1913.J 



In a short note Mr. Nicoll describes the eggs of the 

 Sudanese form of the Crowned Crane which were laid in 

 the Giza Zoological Gardens in the autumn of 1910. They 

 appear to resemble those of the South African form 



B. regulorum in being white with a greenish tinge, and 

 differing from those of the Grey Crane, which are blotched 

 with reddish-brown.
