210 HISTORY OF BRITISH CRUSTACEA. 



Order II. L.EMODIPODA. 



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 Airtphipoda. 



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
