Yet we learn that in the autumn of 1907 migratory flocks 
of this bird were noted at many of the light-houses on the 
east coast, and at St. Catherine’s, I. of W. It may be 
presumed, however, that these were all strangers from the 
far north, and not deserters from our English gardens, where 
they seem to be as numerous in winter as in summer. 
The list of Light-houses and Light-vessels on which 
observations were made should have been accompanied by a 
map, as is always the case in the Danish Report. The exact 
situation of many of them is unknown (except, perhaps, 
to special students of migration), and to the names of the 
meritorious Observers their addresses, surely, should be added, 
unless the Observers object. 
With these slight exceptions we fully approve of the third 
report of our Migration Committee and thank them for their 
good work. 
38. Nicholson on the Distribution of Macronyx. 
[The Geographical Distribution of Birds. I. Genus Macronyx Swainson. 
By Francis Nicholson, F.Z.S., M.B.O.U. Manch. Mem. Lit. Phil. Soc. 
53. 1909, No. 24.] 
This is the first of a proposed series of papers on the 
distribution of Pipits and Wagtails, which the author has 
studied for several years. Of the purely Ethiopian genus 
Macronyx 9 species are allowed, while their exact distribution, 
so far as it is yet known, is set forth and further elucidated 
by two coloured plates. The most widely spread species is 
M. croceus , which is found in West, East and South Africa, 
but others are confined to quite limited localities.
