99. Ottosson on rare Biids' Eggs. 



[Some rare Birds' Eggs. Described by Dr. 0. Ottosson. With one 

 plate. Communicated by Einar LiJnnberg. Arkiv fiir Zoologi, Band 4, 

 No. 9 (1908).] 



This is a paper of considerable importance^ as it describes 

 and figures the eggs of Garrulus lidthi, Emberiza gessoensis, 

 and Plotus rufus. The Jay has plain blue eggs and lays 

 them in hollow tree-trunks ; the nests were found in Amami- 

 Oshima, an island of the Loo Choo group. The parent birds 

 were obtained at the same time as the eggs. The Bunting 

 was discovered breeding in the Tokio district, an extension 

 of its range from Yesso. The Darter's eggs are from the 

 isolated colony at the lake of Antioch described by the late 

 Canon Tristram: they resemble those of Cormorants in their 

 general appearance, but are spotted with brown and violet.

 to the Board of Trustees for the Year 1907. Chicago, U.S.A., 1908.] 



The Report of the Director (Mr. F. J. V. Skiff) to the 

 Trustees on the Field-Museum of Natural History for 1907 

 gives a favourable account of the progress of that great 

 Institution. The plans for the new building have been 

 carefully prepared, but there are some difficulties about the 

 site. The collecting-expedition sent out to British East 

 Africa in 1905 under the leadership of Mr. C. E. Akeley 

 had returned " with a consigment of 84 packages, weighing 

 upwards of 17 tons,^' all in perfect condition. The attention 

 of the expedition had been specially devoted to the larger 

 mammals, of which a good series was obtained, but we see 

 693 bird-skins in the List, on which we shall, no doubt, 

 have a special report in due course. 



The next great expedition contemplated is one to Tibet, 

 under the conduct of Dr. Berthold Lauter, who will devote 

 three years to the exploration of the country. 



In the list of the scientific staff we observe the names of 

 Mr. Charles B. Cory as Curator in the Department of
