ADDENDA. 153 
I have thought it better to add this 
note, as its habit of drinking whilst on 
the wing, may possibly be new to many 
naturalists.

GUILLEMOT, U7via troile. 
The local name for this bird at the 
various places where it occurs on the 
South Wales Coast, is “Elligug” or 
“ Felligog.” Mr. Thos. Henry Thomas 
of the Cardiff Naturalists’ Society says 
that this name is Welsh; ‘‘ Heli” mean- 
ing salt, or saltwater, and “Gog” cuckoo. 
I have to thank him for this note, which 
occurs in his interesting paper entitled 
“A visit to the Gannet Settlement upon 
the Island of Grassholm,” which he 
kindly sent me.
