or uungured, by Messrs. J. A. Bucknill and G. H. Gronvold. 

 Tliese eggs are of 2\trdus cabanisi, from Natal ; Poliohierax 

 seniitorquatiis, from the Transvaal ; Amijdrus morio, Colius 

 indicus, Apalis florisuga, from Cape Colony ; Cinvyris ofer, 

 Tarsiger stellatus, from Natal ; Eutolmaetus spilogaster, from 

 Matabele Land ; Kaupifalco mnnogrammicus, from the Sudan : 

 Bhinopomastus cyanomelas, from the Transvaal ; and Stephan- 

 ihijx melanopterus , from the Transvaal. A second paper treats 

 of the plumages of Saxicola monticola Bechst., and the 

 writer, Mr. C. G. Davies, supports Seebohm's views to some 

 extent, while holding that there is only one species involved, 

 instead of two, but that it is dimorphous. Lastly, Mr. P. 

 A. Sheppard writes on some little-known birds from Beira. 

 Many of them are of great interest (and more especially their 

 nests and eggs), as, for instance, Batis sheppardi, Anthrejjtes 

 reichenowi, and Kaupif(dco monogrammicus, while attention 

 should be directed to the fact that the egg of the last named 

 bird does not correspond with the description given of it 

 in the first paper of this number. 



60. Thienemann on tlie Migration of the Stork. 



[Der Zug des Weissen Storclies, auf Gruud der Resultate, die von der 

 Vogelwarte Rossitten mit den Markierungs Versuclien bislier erzielt 

 worden sind. Yon Dr. .J. Thienemann. Zool. Jabrb., Siippl. xii.] 



This is a complete and well-prepared account of the dis- 

 coveries made by placing aluminium rings on the legs of 

 Storks, and thus obtaining exact information as to the route 

 which they follow in travelling from Northern Germany to 

 South Africa. It has been written by Dr. Thienemann^ the 

 Director of the Bird-Observatory at Rossitten, N.E. Prussia, 

 who is one of the best authorities on the subject, and is 

 illustrated by three plates, which shew the road followed by 

 the Storks from the Baltic to the Cape — so far as it has 

 been yet ascertained. The young Storks are " ringed " 

 when half-fledged, and there appears to be little difficulty 

 about the operation. Some 3000 aluminium rings have 

 been distributed in N.E. Prussia for this purpose. 



No one interested in the great " migration-question '^ 

 should fail to make himself acquainted with Dr. Thienemann's 

 paper on this subject.
