Eiders diving off the coast of Sylt, and they stayed under 

 water for many seconds. These birds, as well as Sheldrakes, 

 always cover their eggs with down before leaving the nest. 



Of the birds included by Rafn in the paper before men- 

 tioned, the following were not seen by us : — 



Muscicapa grisola. Pyrgita montana. 



Erithacus phoenicurus. Strepsilas coUaris. 



Erithacus titys. Tringa minuta. 



Calamoherpe arundinacea. Larus glaucus. 



Alauda cristata. Anser cinereus. 

 Fringilla coelebs. 



The last two, as the editor of ^Naumannia^ noticed at 

 the time, are manifestly introduced in error; the rest are 

 stated by Rafn to have been but scarce. He also includes 

 Anthus campestris in his list ; his words are, " einzelne Paar 

 briiten.^'' I believe we observed this species ; but as I could 

 not satisfactorily identify it, I have thought it better to omit 

 it from my list of species and mention it here. The facts are 

 as follows : — On Sudfall, and again on the north end of Sylt, 

 we noticed Pipits which, from their appearance, could, I think, 

 only be referable to Anthus campestris; they were pretty 

 common on the first-named island, rare on Sylt. Near List, 

 on Sylt, we took a nest with three eggs amongst the coarse 

 grass on the dunes, about two hundred yards above high-water 

 mark, on the east coast of the island ; it was formed of dry 

 grass, the finer fibres towards the interior, and lined with a 

 few coarse hairs ; the owners, however, were not satisfactorily 

 identified. I am sorry I cannot speak decidedly about this 

 species ; but being unable to shoot on land, we could not secure 

 any examples, and, not being very well acquainted with the 

 species of this difficult genus, I am unable to say more. Rafn 

 does not mention Anthus pratensis. It is quite possible that 

 his Calamoherpe arundinacea may have been Emberiza schce- 

 niclus : he says, '' nistet im Rohr bei Keitum ; ich bekam sein 

 Nest mit zwei Eiern und einem Kukuksei.^'' We observed 

 Emberiza schceniclus about six miles north of Keitum amongst 

 reeds and bushes surrounding a '^ Yogelkoje.^' Some of the
