years' close attention to the subject has enabled him to make 

 large additions. The list now comprises the names of 216 

 species. One of the most interesting of these is the 

 Great Sedge- Warbler {Acrocephalus ^Mr</o^</e5), which breeds 

 regularly in the ponds of Riddagshausen. There some years 

 ago the Editor of this Journal had the pleasure of taking with 

 his own hands, under the friendly guidance of the ornitho- 

 logists of Brunswick, the specimens of the nest and eggs of 

 this fine bird which are now in our National Collection. 



10. R. Blasius on Mergus anatarius. 



\_Mergus anatarius, Eimbeck, ein Bastard zwischen Mergus alhelluSf 

 Linne, und Olaucion clangula, Linne. Von Dr. Rudolf Blasius, Monat- 

 schr. d. deutsch. Ver. z. Schutze d. Vogelw. Jalirg. xii. p. 377.] 



Dr. R. Blasius gives us a full account of this singular 

 hybrid between the Smew and the Golden-eye, of which four 

 examples are now known. The first specimen, now in the 

 Brunswick Museum, was obtained in 1885, and called by 

 Eimbeck Mergus anatarius. A second was procured in Den- 

 mark in 1843, a third in Sweden in 1881, and a fourth has 

 recently been described by Herr O. Wolschke, which was 

 shot in Mecklenburg in 1865. Coloured figures are given of 

 two of the specimens.

 Sommer 1887 ausgefiibrten ornithologiscben Forscbungen iibersicbtlicb

This is the full text of the article referred to by Dr. W. 

 Blasius in his letter in last year's 'Ibis' (1888, p. 372). 

 Dr. Blasius gives an account of the collection made in 

 Palawan by Dr. and Mrs. Platen in 1887, and sent to 

 Herr Nehrkorn. It contains representatives of 130 species, 

 and nearly doubles the number of Palawan birds known to 

 the author. It is unfortunate that there should have been a 

 " concurrence " between Dr. Blasius and Mr. Sharpe on this 

 subject, but such things will occasionally happen. Both
