Three more numbers of the new ' Ornithologisches Jahr- 

 buch/ of which we have already mentioned the institution 

 (above, p. 382), have reached us. They contain various 

 articles on Central European birds, of which that which 

 interests us most is an account of the irruption of Pastor 

 roseus into South-eastern Europe in June 1889. In that 

 month large flocks of this remarkable migrant arrived at 

 Knjajevo, near Sophia. Small flocks and wandering indi- 

 viduals appear to have separated from the main swarm, and 

 were met with at different points in Bohemia, Galizia, 

 Moravia, Carinthia, Lower Austria, Croatia, Bosnia, and 

 Hungary. The last great irruption of Pastor roseus took 

 place in 1875 (cf. Verh. k.-k. zool.-bot. Ges. Wien, xxvii. 

 Abh. p. 196).

In this memoir we have a very complete account of the 

 various occurrences of Syrrhaptes within the limits of the 

 Austro-Hungarian Empire. After a list of the publications 

 on the subject, which occupies eight closely printed pages, 

 the fifteen principal divisions of the dual monarchy are taken 

 in alphabetical order, and the various authorities are given 

 for the occurrences of this bird in each of these divisions.
