180 Mr. J. Cordeaux on the Heligoland 



after my visit, Oct. 9th, 1874. This was killed by a boy with 

 a pea-shooter. 



Phylloscopus superciliosus (J. F. Gmelin). 



This most interesting little wanderer turns up regularly 

 every autumn, invariably arriving with N.E. winds. Indi- 

 viduals have occurred from 1859 to 1874 on various days be- 

 tween Sept. 19th and Oct. 16th inclusive. Several are some- 

 times seen which are not obtained. 



Regulus cristatus, K. L. Koch. ^ 



Occurs in the autumn in October in large flocks. 



Dendrceca virens (Gmelin). 



Oct. 19th, 1858, a very good example. Appears to be in 

 transition-plumage, from summer to winter. 



Troglodytes pakvulus, K. L. Koch. 



This little favourite of our gardens and shrubberies is 

 found in considerable numbers in the autumn in the small 

 enclosures attached to the houses in the town, as well as 

 on every part of the bleak exposed headland, and even on the 

 cliffs themselves. Mr. Gatke had no doubt whatever of its 

 migratory habits. I have long held the same opinion ; for 

 whence come the number we invariably find in October in our 

 treeless and exposed Lincolnshire and Holdemess marsh dis- 

 tricts, as well as amongst the marram-covered sand hills along 

 the coast ? 



Parus major, Linnaeus. 



AcREDULA CAUDATA (Liunseus) . 



In the collection. This is the Scandinavian bird with the 

 pure white head. 



Ampelis garrulus, Linnaeus. 

 Accidentally, late in the autumn. 



MoTACiLLA LUGUBRis, Tcmmiuck. 



MoTACiLLA ALBA, Liunseus. 



MoTACiLLA VIDUA, Suudcvall. 

 May 18th, 1866.
