HISTORY OF BRITISH CRUSTACEA. 
Order II. L2EMODIPODA. 
This Order is restricted to a small number of species, all 
of curious form, in which the abdominal portion of the 
body is in a very rudimentary state, being represented by a 
scarcely visible tubercle. Body cylindrical or depressed ; 
head very small; the six thoracic rings very distinct; legs 
exposed at base ; sometimes there are seven pairs, some- 
times five, third and fourth pairs sometimes represented by 
tubercles from which spring lamellar or vesicular appendages. 
The female has the egg-pouch on the second and third 
rings. Mr. Spence Bate merges this Order in Amp/iipocla. 
Mr. Gosse has given much information on the habits of 
the British species, in one of his works.* He is describing 
the genus Caprella . These Crustacea are found on the 
pinnated branches of the zoophyte, 'Plumularia cristata . 
“ They are as much at home in the tree-like zoophyte as a 
family of monkeys in their arboreal bowers; and indeed 
their agility, as they run from branch to branch, catching 
hold of a twig just within reach, and pulling themselves in 
an instant up to it, then stretching out their long arms in
