112 NILS GYLDENSTOLPE, ZOOLOGICAL RESULTS OF THE SWEDISH ZOOLOGICAL EXPEDITIONS TO SIAM. 
inhabits Northern Mongolia and Eastern Siberia. My specimen agrees well with the 
type-specimen of U. e. saturata in the collections of the Royal Nat. Hist. Museum of Stock- 
holm. The long crest-feathers are perhaps a trifle brighter. The upper parts of the body 
are very dark being almost dark greyish brown, gradually shading into the rufescent 
brown of the upper neck. 
My specimen has considerably shorter wings, as seen by the measures given above, 
than any specimens of U. e. satwrata in our collections which have their wings measuring 
151 & 141 mm. respectively.

The Great Hornbill generally occurred in small flocks throughout almost all of the 
well-wooded parts of Siam. It lives entirely on fruits and keeps to the highest trees, 
where it is not easy to obtain, as it is very shy too.
