48 Yorkshire Naturalists’ Union: Annual Report, 1910. 
Yorkshire Mammals, Reptiles and Fishes Investigation 
Committee.— Numerous observations of interest and importance 
have been reported, and mention should be made of the appear- 
ance of the first part of Major Barrett-Hamilton’s long-expected 
and much-needed work on the British Quadrupeds, which is of 
high scientific standard as regards the text, though very disap- 
pointing as regards the plates. It is satisfactory to find that the 
work of our Yorkshire observers obtains prominent mention. 
Land Mammals.—Mr. Arthur Whitaker reports the capture 
of two Hairy-armed Bats ( Nyctalus leislert) at Worsborough Dale 
on 21st July, and Mr. H. B. Booth that although he has never been 
able to find any trace of Daubenton’s Bat (Vespertilio daubentonit) 
in Upper Airedale, it is not uncommon along the river Wharfe, 
between Bolton Abbey and Burley, and that he has frequently 
observed it flying just over the water in the late evenings. and 
has examined one taken just above Ilkley, nearly at Nessfield. 
The Lesser Shrew (Sorex pygmaeus) has occurred to Mr. 
Greaves at Hebden Bridge this summer, and Mr. H. B. Booth 
took or examined during May and July no fewer than four of this 
species, along a seven-mile stretch of the river Wharfe, between 
Denton and Bolton Abbey. Previously, we have only known 
of two records in twenty years or more. All these four were 
taken on the north side of the river Wharfe. 
The reported occurrence of the Marten (Martes sylvestris) in 
Littondale is open to doubt, and needs investigation. 
A case of albinism in the Stoat is reported by Mr. Riley 
Fortune, a white one having been obtained at Bedale at the 
beginning of September. 
Although in small numbers, the Dormouse holds its ground, 
and the colony in the wood near Goathland of which Mr. Oxley 
Grabham took photographs last year, is steadily increasing in 
numbers. 
Marine Mammals.—Mr. W. J. Clarke reports that a Common 
Rorqual (Balenoptera musculus), fifty-one feet in length, was 
washed ashore, dead, at Cloughton Wyke, on the 27th March; 
and another one was washed ashore within half a mile of the first 
specimen at a later date. The second example, which had been 
dead some time, measured sixty-nine feet in length, and fourteen 
feet across the caudal fin. 
Reptiies.— Mr. Oxley Grabham notes that a twenty-two inch 
Viper was killed on the Goathland Moors in the act of swallowing 
a young Curlew, three or four days old ; and in the “ Zoologist,’” 
the Rev. W. Warde Fowler notes the occurrence of an unusual 
variety of the same species at Danby Dale, in which the usual 
zig-zag markings were replaced by a broad black band down 
the back. 
Amphibians.—Mr. H. B. Booth notes that although the 
Palmated Newt had been looked upon as the scarcest of the 
Naturalist,
