Altogether now a total of 329 species—a splendid list. Several o - 
these during the same period have also occurred on the Lincolnshire e 
side of the Humber, also four which so far have not been recorded 
for Yorkshire. These are the American Red-breasted Snipe (Mace : 
rhamphus griseus), Indian Roller (Coracias indicus), Water Pipt 
(Anthus spipoletta), and this year, in September, the Greenish Tre | 
Warbler (Phylloscopus viridanus) shot on the Lincolnshire coast, near 
North Cotes, by Mr. G. H. Caton Haigh. This is an Asiatic speci® ; 
which bears a strong resemblance to the Arctic Willow Wren, the bi, — 
however, being much smaller. This is the third occurrence 
Europe, having previously twice occurred on Heligoland. 
In the autumn of 1877, I commenced taking observations on the : 
migration of birds, by sending schedules and letters of instruction - 
the lighthouses on the north-east coast, from Spurn to the ip 
mouth. The result of the first enquiry was interesting from ® 
number of Blackbirds recorded at Spurn and Flamborwngt # | 
November, more particularly in the last week of that month. 
1879, in conjunction with Mr. Harvie-Brown, we worked the Ware 
cast coast of Great Britain, from the Shetlands to the English 
Channel. From 1880 to 1887 inclusive, the work was undertake? 
by a Committee of the British Association, for all the coasts = : 
Britain and Ireland and outlying islands, and annual reports : 
published, — 
In 1888, one of our Committee—Mr. Wm. Eagle Clar 
former Secretary of this Union-—was instructed to make a par . 
the whole of the information furnished to the Committee, °! 
examination de novo of the whole of the vast mass of ame 
schedules. This work, after immense labour, was only ee read 
the present year, and (in Mr. Clarke’s absence) presented sation i 
by me, as Secretary, at the Liverpool meeting of the meee z 
September. ‘The Times,’ in commenting upon the work on the 
this meeting, says: ‘The long report by Mr. Eagle Clarke, ' 4 work 
migration of birds, was one of the most valuable pieces of - 
Presented to the section,’ : con
