require. In English, the best book is the late Professor Bell's 
‘History of the British Stalk-eyed Crustacea,’ published so long 
ago as 1853. At the date of its publication it was no doubt all 
that could be desired, but since 1853 several species have been 
added to the British fauna, and many which he considered rare 
are no longer so. This work will be found indispensable, for 
with the plain descriptions are beautifully-executed woodcuts of 
every species then recognised as British. Following in his wake the 
late Adam White compiled a useful little book entitled ‘A Popular 
History of British Crustacea.’ This brought the subject down to 
1857, with several additions to our fauna. White gives short 
descriptions and a few additional localities other than those 
mentioned by Bell. Mr. P. H. Gosse, in 1855, published his 
‘Manual of Marine Zoology,’ in which, of course, he alludes 
to the Crustacea, but gives only generic descriptions. For the 
species added to our fauna since 1857 we have to search through 
scattered papers in various scientific journals, published not only 
in London, but also in the provinces. It is hoped that there may 
be issued shortly a synonymic list (which will be useful also for 
cabinet labels), bringing the subject up to the present time. 
For the classical work on the Crustacea we have to go to our 
neighbours, the French; the ‘ Histoire Naturelle des Crustacés’ 
of M. Milne Edwards, published in Paris in 1834, being the work 
of all others on the group. It treats of all species known to the 
author at the date of publication, and refers not only to the Stalk- 
eyed, but also to the Sessile-eyed, Crustacea. The scientific 
descriptions are in French, but are easily read. The arrangement 
used by M. Milne Edwards is the one generally followed at the 
present time. 
Amongst the earlier English writers on the subject, perhaps 
the most important was Dr. William Elford Leach, who, in 
1815—17, published his ‘ Malacostraca Podophthalma Britannie, 
or Descriptions of the British Species of Crabs and Lobsters.’ 
This fine work contains quarto plates, with coloured figures of 
many species. We need hardly remind our readers that Dr. Leach 
was Curator of the British Museum up to 1821, but died in Italy 
when scarcely past middle age, quite broken in health and 
intellect. Pennant, in his ‘ British Zoology ’ in 1777, gives some 
plates of British Crustacea. Montagu, in 1804, described those 
species known to him as occurring on the Devonshire coast.
