most frequent occurrence were Alauda arvensis, Sturnus 
vulgaris, Turdus iliacus, T. musicus, Erithacus rubecula, and 
Fringilla moritifring ilia. The commonest migrant of all 
appears to be the Song-Thrush, of which it is calculated 
that at least 4492 specimens were noticed. Yet this bird 
(in spite of what Newton told us long ago, see f The Ibis/ 
1860, p. 83) is not usually considered to be a migratory 
species !

of the Ruwenzori Expedition in this Journal and an account

publish the results*, but this volume is the first regular 
narrative of the Expedition that has been made public. 
Dr. Wollaston was not able to start along with the other 
members of the Expedition, and when he caught them up 
found them already well established in camp at Bihunga, on 
the eastern slope of Ruwenzori, in the Upper Mubuku 
Valley. Here the party remained for very nearly four 
months, and found no lack of occupation in any branch 
of natural history. For the first month the weather was 
uniformly fine. “Day succeeded day of bright sunshine 
and cloudless skies : it was neither too hot by day, nor too
