Garriilus lidthi. 



From the time this beautiful jay was rediscovered I 

 strongly desired to obtain eggs and full information about 

 its breeding habits. My endeavours ha ve been crowned with 

 success so far, as a Japanese collector during an expedition to 

 the island Amami-Oshima of the Loo Choo group south of 

 Japan was liappy enough to find two nests of this bird the 

 contents of which viz. 3 & 4 eggs I had the pleasure of receiving 

 some weeks ago. The bird is not found elsewhere which ex- 

 plains the remarkable fact that so long time elapsed between 

 the description of the first specimen and the rediscovery of 

 the species. 



The nests were situated in hollow tree trunks. The two 

 sets were collected resp. the 29th and 30th of March. The 

 eggs appear to have been quite fresh and new laid, 3 in one 

 ^nd 4 in the other clutch. With regard to the colour they 

 resemble completely the eggs of the common Starling {Stur- 

 nus vulgaris) and give the impression of gigantic Starling 

 eggs. The blue colour is exactly the same in both. 



Size: 33,4 X 24,i— 33,i X 24,6—32,6 X 24,4, and in the 

 other set 34,4 X 24,2—33,7 X 24,6—32,7 X 24— 32,3 X 24,8 mm. 



Weight: 67— 66,. ö — 66, and in the other set 60—60—55 

 — 63 ctgm.
