The Glenelg specimens are interesting as showing the extreme west 
limit of S. aranews on the mainland. Glenelg is opposite Skye, where 
the Channel is narrowest. The dentition of the Skye specimen also 
agreed with that of S. araneus.—P. A. Buxton (32, Great Cumberland 
Place, London, W.). 
White Water Vole-——On April 27th a man lopping trees near the 
water-mill at Little Glemham, Suffolk, killed an albino Water Vole 
(Arvicola amphibius). The fur was of the purest white all over, 
long, soft, abundant, and shining; the eyes red. It was a young 
animal, about three parts grown, and must, I think, have been born 
last autumn.—G. T. Rope (Blaxhall, Suffolk). 
AVES. 
Mimicking Song of Chiffchaff.—lI have been watching a Chiffchaff 
here for some days which almost invariably concludes its normal song 
of ‘chiffchaff’’ with an exact reproduction of the song of the Willow- 
Wren. There is no interval between the two songs, the “chiffchaft” 
part always coming first. One would hardly expect to meet with 
mimicry in a Chiffchaff, if such it should be—or is there any other 
possible explanation of its having the song of the two species? This 
bird arrived and commenced its song as above described before I 
could find any Willow-Wrens about.—H. Mryrick (Hampstead). 
The Great Black Woodpecker.— On several occasions I asked 
readers of ‘The Zoologist’ to let me know if they could trace a loud 
melodious cry which I frequently heard when at Schinznach, near 
Basel, and also at Strassburg, &. I wish now to say that I feel 
assured it proceeds from the Great Black Woodpecker (Pzcus martius), 
as I heard it last July at Helenen, above St. Nicolaus, in the Zermatt 
Valley, and was assured that the ‘“‘specht”’ there was the ‘“‘schwarzer.” 
I heard it first years ago at the Signal Hill at Belveden, near Bex 
(Vaud), and immediately afterwards saw the bird, “like a chicken,” 
flapping with rapid beats of the wing from tree to tree. The note
