NOTES AND OBSERVATIONS ON BRITISH 
STALK-EYED CRUSTACEA. 
By Epwarp Loverr. 
(Continued from p. 106.) 
Nephrops norvegicus, Leach. 
Tue Norway Lobster, as this species is called, is one of the 
most beautiful, as it is one of the most remarkable, forms 
frequenting our shores. Its graceful form and brilliant colour 
would be calculated to give the idea that its habitat was the 
luxuriant coral groves and pools of tropical islands; whereas it is 
really a species which, if not actually confined to northern areas, 
is certainly more abundant as a boreal type, and, as far as the 
British Islands are concerned, it is undoubtedly rare—if indeed 
it occurs at all—on our southern coasts, whereas it is exceedingly 
-abundant on the shores of the cold unfriendly north. 
This fact is a curious and interesting one when viewed from 
the standpoint of colouration as adapted to surrounding conditions. 
Nephrops norvegicus is a lobster of a decidedly pink colour, and 
occasionally the tint is quite coral-like in its brightness; it is 
therefore an animal easily seen, and consequently easily captured 
by its enemies, contrasting as it does with the dull muddy shores 
of the Northumberland coast, or even the coast of Norway, where 
it is particularly abundant; whereas if its habitat had been a 
southern one, where brilliantly tinted Algee crowded the bright 
granitic rock-pools of an almost semi-tropical shore, its peculiarly 
striking tints would appear to be of some service in protecting 
it from the attacks of predatory fishes.
