 by Professor Lonnberg is that the bones are those of Anser

 brachyrhynchus.

97. Nehrkorn's Catalogue of Eggs. 



[Katalog der Eiersammlung, nehst Beschreihungen der aussereuro- 

 paischen Eier. Yon Adolph Nehrkorn. Zweite Aufl. Mit4 Eiertnfeln 

 infarbigem Steindruck. Berlin: Friedlfinder, 1900. 1 vol., 8vo, 449 pp.] 



This is a second edition of the Catalogue of the great 

 collection of birds' eggs formed by Herr Adolph Nehrkorn 

 of Biddagshausen, near Brunswick, and now in the Museum 

 of Berlin (or on its way there), the owner having liberally 

 presented it to that Institution. It is without doubt one of 

 the largest and most complete collections of these beautiful 

 objects ever made, no trouble or expense having been spared 

 in amassing it. The Catalogue follows Sharpe's ' Hand-list ' 

 of Birds in arrangement and nomenclature. It enumerates 

 the names of 5440 species, the eggs of which are represented 

 in the Collection. Short characters are given of the eggs of 

 non-European species, and the patria is stated, but un- 

 fortunately no authorities for the identification are added. 



Many rarities are represented in the series, such as examples 

 of the eggs of eleven species of Galapagoan Finches, of six 

 species of Paradise-birds, of Calyptomena viridis, Nasiterna 

 pusio, and Chunga burmeisteri. There is an excellent alpha- 

 betical index, and four good coloured plates of thirty-seven 

 special rarities.
