BRITISH STALK-EYED CRUSTACEA. 255 
which conditions organs of vision tend to decrease in power and 
structure, as in the remarkable instance of the sightless deep-water 
species Calocaris macandree, referred to in a former article. The 
animal we are now considering possesses perhaps the finest eyes— 
certainly in proportion to its size, &c.— of all our stalk-eyed species. 
The colour of Nephrops norvegicus, as I have already stated, 
is pink, or salmon-colour, varying slightly in shade. Its length 
is eight or nine inches, exclusive of the anterior pair of legs, 
which are about the same length. 
This species is really a boreal one, although Bell records it 
from the Mediterranean, and alludes to its occurrence in the 
Adriatic, as chronicled by Prof. Milne-Edwards; he also notes it 
as being not at all uncommon on the Berwickshire coast, and 
amongst other localities he enumerates the Firth of Forth, Loch 
Fyne, Belfast Lough, Strangford Lough, and off the coast of 
Down. It is also said to be largely used as food in Dublin— 
human food, of course, although it is commonly found in the 
stomachs of the Dublin Bay codfish, showing that it is also 
valued as food by crustacean-eating fish. In Newcastle it is sold 
very cheaply indeed, and is there called a prawn. In the Reports 
of the British Association, and in the ‘ Natural History Review,’ 
this species is also recorded from Dublin Bay, Galway, and 
Moray Firth. 
In the Transactions of the Tyneside Naturalists’ Field Club 
(p. 154), my friend Mr. Henry Tuke Mennell says :—‘ Owing to 
the recent introduction of trawling in this district large numbers 
of the pretty little lobster Nephrops norvegicus have been caught, 
and have been sold at fish-shops in the town. It has been a 
favourite article of food in Scotland; but in this district it has 
been unknown in this capacity. Its flesh is more delicate in 
flavour and less tough than that of the common lobster, but 
unfortunately there is less of it.” 
As regards the embryology of this species I am unable to say 
anything, as I have never seen its ova or zoca. 
Nephropsis cornubiensis, Bate. 
In the British Association Report for 1880, p. 160, a figure is 
given of the above, and it is said to have been dredged off the 
Dudman, but I do not know more regarding it; and if it bea 
new species it is not apparently much known.
