or unfigured, by Messrs. J. A, Bucknill and G. H. Gronvold. 
These eggs are of Tardus cabanisi , from Natal; Foliohieraoc 
semitorquatus , from the Transvaal; Amydrus morio, Colius 
indicus , Apalis florisuga, from Cape Colony ; Cinnyris afer, 
Tarsiger stellatus, from .Natal ; Eutolmaetus spilog aster rom 
Matabele Land; Kaupifalco monogrammicus , from the Sudan ; 
Rhinopomastus cyanomelas, from the Transvaal; and Stephan - 
ibyx melanopterus, from the Transvaal. A second paper treats 
of the plumages of Saxicola monticola Bechst., and the 
writer, Mr. C. G. Davies, supports SeebohnTs 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 , Anthreptes 
reichenowi , and Kaupifalco 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 the Migration of the Stork. 
[Der Zug' des Weissen Storches, auf Grand der Resultate, die von der 
Vogelwarte Rossitten mit den Mavkierungs Versuchen bisher erzielt 
worden sind. Yon Dr. J. Thienemann. Zool. Jahrb., Suppl. 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 Bossitten, 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^ 
paper on this subject.
