Anthus Richardi, Emberiza pusilla (two shot), E. aureola (seen) ; 
28th, H. pusilla (two seen), H. rustica (one shot); 29th, Sylvia 
superciliosus (one); 80th, Hmberiza pusilla (one); Oct. 1st, HE. pusilla 
(one); Nov. 2nd, 3rd and 4th, westerly winds and nothing, but 
daily some Parus ater; on the Sth, again, Anthus cervinus (seen 
and heard); northerly winds, sometimes N.E. on the 8th, a Leaf 
Warbler seen at close quarters, but not procured by Aeuckens, 
the Heligoland birdstuffer, which Mr. Giitke feels tolerably certain 
Was a very rare visitant; the same day there were two or three 
HE. rustica, and one each of A. pusilla and A. cervinus. ‘The rare 
Leaf Warbler was again seen on the 9th, but could not be obtained ; 
an Emberiza rustica was also seen. On the 10th, E. pusilla shot 
and H. rustica seen. On the 12th, Muscicapa parva and Motacilla 
lugubris, which latter comes there rarely inautumn. On the 14th, 
Sylvia superciliosus was shot by Mr. Giitke’s eldest son, and two 
more were seen by Aeuckens in a garden where shooting was not 
permitted. On the 18th, one very fine HL. pusilla shot. On the 20th 
Lestris afinis was seen close by, but not shot, as it would have 
fallen in the sea and drifted away. ‘This is the third, if not the 
fourth, known occurrence of the Siberian Herring Gull at Heligo- 
land. On the 24th a large Redpoll was shot, which Mr. Giitke 
thinks can only be the Greenland bird, Linota Hornemanni. 
A summary of the various returns show that four species, 
Larks, Starlings, Rooks and Hooded Crows, in the order given 
respectively, far outnumber any other, and of these four the Lark 
far exceeds the rest in migratory numbers, As a rule, the lines of 
migration followed have been from E. to W., or 8.E. to N.W. 
direct on to the English coast. ‘To the middle of October we find 
birds rarely coming from points north of east; after this date they 
appear to come occasionally from directions north of east, between 
east and due north. ‘The line of migration of the Anatide has 
been from north to south, crossing the line of the Insessores at 
right angles. 
There is one remarkable exception to the general rule of an 
east to west route in the case of the lightvessel on the Galloper 
Bank, forty miles 8.8.E. of Orfordness. All entries in this return 
show birds passing to the E. or 8.8.E. or 8.E. during October. 
We can only account for this anomalous line by supposing the 
birds which cross the Galloper have previously struck the English 
coast at some higher latitude, and after skirting the coast line
