XIV.— Letters , Extracts , and Notes. 
We have received the following letters addressed to the 
Editors :— 
Sirs, —A few notes on my route during the last nine 
months and on my plans for next year may be of interest to 
the readers of * The Ibis/ In May last, along with my com¬ 
panions, Messrs. Miller and Price, I travelled through Siberia 
to the Yenisei River, and spent several months in exploring its 
head-waters in the Syansk and Tannu-ola mountain-ranges. 
We found this district, although within the Chinese 
Empire and on the threshold of Mongolia, to be quite 
Siberian in character and to possess a Siberian fauna. 
Forests of larch, spruce, birch, and Scotch fir, interspersed 
with meadow-lands, and watered by fine rivers, stretch as far 
south as the Tannu-ola Mountains, and this range (lat. 51°) 
forms the true “ divide 33 between the Siberian and Mongolian 
faunas. I made a small collection of birds, which includes 
examples of the following, among other species Ptarmigan, 
Brown Partridge, Hazel-Grouse, Great Black Woodpecker, 
Capercaillie, Black-throated Thrush, Golden Oriole, Cross¬ 
bill, and various other species. The spring migration was 
on the whole rather later than it is in England. 
The existence of Sable, Beaver, Reindeer, and Moose also 
shews the affinities that this district possesses to Siberia. 
On leaving Arctic waters and entering Mongolia proper I 
immediately perceived a change in the fauna.
