In 1880 a specimen of this species was repeatedly seen in the 
Kyle of Tongue in August, as reported to us by Mr. 
J. Crawford of Tongue House, and there are other records 
of its occurrence on the north coast of Caithness (vide Bell, 
Brit. Quad. p. 441). A specimen was obtained at the Little 
Ferry on the 9th of June 1879, having been entangled in the 
gearing of the salmon stake-nets (P. Z. S., 1879, pp. 667-9). 
It is now stuffed and in the Dunrobin Museum. 
Professor Struthers has kindly sent us a note of a Beluga 
or white whale taken alive in the salmon-nets at Dunbeath, 
on April 26th, 1884. It was obtained for the Professor by 
Mr. Adam Mackay, and forwarded to Aberdeen on April
