BRITISH STALK-EYED CRUSTACEA. ‘99 
Continental writers on the subject include Linneus, in the 
twelve editions of his ‘Systema Nature,’ from 1735 to 1766; 
Fabricius, in his several works on Insecta (1775 to 1787) refers to 
this group; Herbst, from 1790 to 1804, published his fine work, 
‘Versuch einer naturgeschichte der Krabben und Krebse,’ pro- 
fusely illustrated with sixty-two coloured plates ; Lamarck (1801); 
Latreille (1805); Risso (1815); Roux, ‘ Crustacea de la Medi- 
terranée’ (1828); and others of more or less importance. 
For a work on the anatomy of these animals, all students 
should carefully read Professor Huxley’s recently published 
manual on “ The Crayfish.”* This treatise once mastered, little 
trouble will be experienced with the anatomy of other members 
of the Podophthalma. 
The next subject to be referred to is the distribution of the 
British Crustacea, and this is so general that the difficulty would 
be to find a part of our coasts where some species or other does 
not occur, though some localities are more favoured than others, 
and the connection between some species and the geological 
character of the coast line is of sufficient interest and importance 
to be particularly noticed when we come to treat of the species 
referred to. Rock pools, sandy, and even muddy shores, as well 
as deep water, all yield their various species, and a few words as 
to methods of capture may be acceptable. It is here that some 
difficulties present themselves, for it is not always convenient or 
possible to go on dredging or fishing expeditions oneself, and, as 
the numerous dredgers and trawlers of our coasts are undoubtedly 
the best sources from whence to obtain specimens, it is very 
desirable to be able to explain the species or genera that are 
required. This is extremely difficult, owing to the local names 
which almost everywhere exist, and by which alone the specimens 
are there known. It is only by becoming conversant with such 
local nomenclature, and by overcoming the propensity which 
fishermen have of throwing away all “rubbish,” that most 
valuable species may at times be obtained, and often in large 
quantities. Other sources which may be personally worked 
are lobster and crab pots, which are used in large numbers 
on the more rocky parts of the coast, and about which we hope 
to say more when we come to treat of the species which are most
