SOME MINOR CRUSTACEANS. 



crawling up the perpendicular faces of rocks about half-tide 

 mark ; and the finder will not need to have explained to him the 

 fact that it is related to the terrestrial Woodlouse or Slater of 

 our hedgebanks. The whole tribe have the respiratory appa- 

 ratus adapted for breathing air, but they appear to require a 

 damp atmosphere. 



Among the fringing weeds 

 of the rocks there will be 

 found great numbers of 

 a lively creature of some- 

 what similar build to the 

 Ligia, but very narrow 

 (oblong-ovate is the tech- 

 nical description), and with- 

 out the terminal appendages 

 (uropods] of that creature. 

 It varies in colour from 

 pale -brown to a dark-brown, 

 perhaps mottled with black. 

 There are several British 

 species, but the common 

 shore-haunting kind is Idotea 

 manna. Its great variation 

 has caused it to be called 

 by at least a dozen names. 



In turning over any or- 

 ganic remains above the 

 reach of the waves, we shall 

 uncover swarms of the 

 Shore-hopper (Orchestia 

 Uito^ed), distinguished from the similar Sand-hopper (Talitrus 

 locusta} by its more compressed body, and by having both the 

 first and second pairs of feet clawed, whereas in Talitrus the 

 second pair are not clawed. 



Among the dried up, black-looking foliage of Lichina 

 pygmcsa, which grows on the rocks that are covered only for 



SEA SLATER.
