for Parus Ivzonensis aud P. semilarvatus , and ^githospiza 

 for Parus fringillinus Fisch. & Rcbw. The name Neositta 

 is suggested in place of Sitella, because it is alleged that 

 Rafinesque in 1815 used Sitella as equivalent to Sitta. This 

 change appears to us to be quite unnecessary, as Rafinesque 

 did not define his name, which may be safely left in oblivion. 

 Herr Hellmayr considers Salpornis emini of Hartlaub as 

 probably distinct from S. salvadorii, although Shelley and 

 Sharpe agree in uniting these two supposed species. He has 

 examined Hartlaub's type. 



131. Helms on the Food of Danish Owls. 



[Om nogle danske Uglers Gylp. Af 0. Helms. Vidensk. Medd. fra 

 deu natiirh. Foren. i Kjobenhavu, 1901, pp. 55-65.] 



The author has carefully examined a large number of the 

 '^ castings " thrown up by individuals of the four ordinary 

 species of Owls that inhabit Denmark — Syrnium aluco, 

 Athene noctua, Otus vulgaris, and Strix flammea, and gives 

 the contents of the castings in a series of tables. These 

 shew that by far the greater portion of the Owls' food con- 

 sists of small mammals (Insectivora and Rodentia), though 

 remains of small birds (Passer domesticus &c.) are occasionally 

 ejected. 



132. Jacobi on Biogeographical Distribution. 



[Lag-e und Form biogeographisclier Gebiete. Von Dr. Arnold Jacobi. 

 Zeitschr. d. Gesellsch. f. Erdkunde zu Berlin, xxxv. Heft 3, 1900.] 



Dr. Arnold Jacobi's essay on Biogeographical Regions 

 should be read by all students interested in the subject, 

 although some of the conclusions at which he has arrived 

 are not to be commended. On the whole he adopts the 

 primary division of the globe into Arctogsea, ^Neogsea, and 

 Notogcca, but makes three '' Regions '' out of the first, five 

 out of the second, and two out of the third — thus raising the 

 Regions to ten in number, and rating the Hawaiian Archi- 

 pelago and New Zealand as of equal value to Africa and 

 South America. Again, to get over the difficult question of
