in that country in 1912, on wliicTi there are articles con- 

 tributed by Dr. K. Lambrecht, K. Hegyfoky, Dr. Weigold, 

 L. Schenk, and the Editor. The general conclusion seems 

 to be that the migration during March was earlier, and that 

 from March 31 to May 7 was distinctly later than the 

 normal, due to the bad weather which occurred at the end of 

 March and beginning of April. The amount of material — 

 observations recorded — is very large, and it is all plotted out 

 for each species according to a geographical plan. 



There are also several articles dealing with the ringing 

 of birds in Hungary. The three species chiefly chosen for 

 this purpose are the White Stork, the Swallow, and the 

 Black-headed Gull, of which 628, 1 166, and 684 respectively 

 were ringed. The Storks travelled south to South Africa 

 (4 examples recaptured) and south-east to Muscat, in 

 southern Arabia, a new line of migration. The Black- 

 headed Gulls seem to travel chiefly south-west to Italy 

 and Tunis. The ringing o£ Swallows seems to have clearly 

 brought out the fact that individual birds nearly always 

 return to the same spot, and even to the same nest, year after 

 year. One bird in particular, ringed in 1908 by Peter 

 Miiller, is known to have returned to the same nest for six 

 successive years. 



An important anatomical paper by Dr. Greschik deals 

 with the submaxillary glands of various species of birds, 

 and gives some account of their secretions and their use 

 in digestion. This is illustrated by two plates. Finally, 

 there are two papers on fossil birds ; one, by Dr. Shufeldt, 

 on the affinities of an extinct Ostrich-like form, Diatryma 

 gigantea Cope, and D. ajox Shufeldt, from eocene beds 

 in Wyoming, U.S.A., and another, by Dr. Lambrecht, 

 giving a list of bird-remains chiefly of quaternary age 

 found in various caves in Hungary and now in the collection 

 of the Central Bureau. 



There are also a number of shorter papers which we 

 cannot even give a list of. As previously, ' Aquila ' is 

 printed bi-lingually in Magyar, and either German or 

 English, in parallel columns.
