383 Recent Ornithological Publications. 



Mr. Hewitsou, indeed, has twice over figured (Br. Ool. pi. xlv.^ 

 and Eggs B. B. 1st ed. p. ii. fig. 3) one specimen tinged with 

 rust-colour, but he has subsequently suggested (Eggs B. B. 2nd 

 ed. p. 17) that the markings thereon were only dirt-stains. 

 This is probably the case, supposing the egg to be really that 

 of the Sea Eagle — a fact by no means certain, if, as we have 

 been informed, all that is known about it is that it came from 

 the island of Hoy, where the Golden Eagle used to breed a 

 ^Qw years ago. 



4. Scandinavian and Russian Publications. 

 We are informed that a third series of the ' Naturhistorisk 

 Tidsskrift ' — formerly well known under the editorship of Prof. 

 Kroyer, but which ceased to appear about twelve years ago — 

 has been commenced. This continuation is conducted by Prof. 

 Schiodte, and its second number contains " Some Observations 

 on the Birds of Denmark, especially as regards Vendsyssel" 

 (a district in the northern part of Jutland), by Herr Fischer of 

 Copenhagen. The portion of the paper published treats only of 

 the birds of prey ; but its author adds two species to the fauna 

 of that country, though one of them, Strix scops, having been 

 taken only on board a steamer in the North Sea, can hardly be 

 considered a legitimate addition. The other. Circus pallidus, 

 was obtained on terra firma, and so far may be justifiably en- 

 rolled as an occasional visitor to Denmai'k, if it has not been, as 

 Herr Fischer considers, formerly overlooked in Jutland. 



The 23rd volume of the ' Contributions to the Knowledge of 

 the Russian Empire'*, published by the Imperial Academy of 

 Sciences of St. Petersburg in 1861, contains Prof. Radde's 

 account of his travels in Eastern Asia from 1855 to 1859. In 

 the narrative of the four expeditions made by this active explorer 

 during this period will be found very many observations on 

 natural history of all sorts, and in particular frequent notices 

 of the occurrence of birds, many of which are of very great 

 interest. The times of the appearance of migrants going north
