Anthus Richardi, Emheriza imsilla (two shot), E. aureola (seen); 

 28th, E. jmsilla (two seen), E. rustica (one shot) ; 2yth, Sylvia 

 superciliosus [one); ^Oth, Emheriza piisilla (one); Oct. liit,E.pusilla 

 (one) ; Nov. 2nd, 8rd and 4tli, westerly winds and nothing, hut 

 daily some Parus ater ; on the 5th, again, Anthus cervinus (seen 

 and heard); northerly winds, sometimes N.E. on the 8th, a Leaf 

 Warhler seen at close quarters, hut not procured hy Aeuckens" 

 the Heligoland hirdstutier, which Mr. Giitke feels tolerahly certain 

 was a very rare visitant ; the same day there were two or three 

 E. rustica, and one each of A. jnisilla and A. cervinus. The rare 

 Leaf Warhler was again seen on the 9th, hut could not he ohtained; 

 an Emheriza rustica was also seen. On tlie 10th, E. pusilla shot 

 and E. rustica seen. On the 12th, Muscicapa parva and Motacilla 

 luguhris, which latter comes there rarely in autumn. On the 14th, 

 Sylvia superciliosus was shot hy Mr. Giitke's eldest son, and two 

 more were seen hy Aeuckens in a garden where shooting was not 

 permitted. On the 18th, one very fine E. pusilla shot. On the 20th 

 Lestris affinis was seen close hy, hut not shot, as it would have 

 fallen in the sea and drifted awa}'. This is the third, if not the 

 fourth, known occurrence of the Siherian Herring Gull at Heligo- 

 land. On tlie 24th a large liedpoU was shot, which Mr. Giitke 

 tliinks can only be the Greenland bird, Lhtota Hornemanni. 



A suunnary of the various returns show that four species, 

 Larks, Starlings, liooks 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 S.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 the}' 

 appear to come occasionally from directions north of east, between 

 east and due north. The line of migration of the Anatidce 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 S.S.E. of Orfordness. All entries in this return 

 show birds jiassing to the E. or S.S.E. or S.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, auct after skirting the coast line
