AMATHILLA SABINI.

in the herring nets at Bray on the coast of Ireland ; 
they have been sent to ns by Mr. Webster from 
Tenby and Falmouth : we have taken them on the 
coast of South Wales; and Mr. Loughrin has sent them 
us from Polperro. We have, however, failed to detect 
them among a large number of individuals found at 
Plymouth. Rathke, Liljeborg, and Bruzelius have ob- 
tained them on the eastern shores of Scandinavia. 
A. Sabini was originally brought from the Arctic seas 
by General Sabine, the President of the Royal Society, 
after whom it was named. The specimens from that 
locality are more than an inch long, nor are many of 
those that have been sent to us from the Moray Frith, 
Berwick Bay, and the coast of Northumberland much 
smaller. 
In colour the smaller animals resemble some of the 
freshest which we have seen of A . Sabini . 
It is remarkable that the size of the individual animal 
decreases in regular proportion as it progresses south- 
wards. In the Shetland and in the Moray Frith it is 
almost as large as in the arctic regions ; at the Menai 
straits it is scarcely half as large, and on the southern 
shore of England it reaches its minimum, and as far as 
we have ascertained, it extends no further southwards. 
The specimen referred to by Mr. A. White, in the 
British Museum, from the “ Isle of Wight?” is, however, 
nearly as large as some of the northern specimens.
