the Channel Islands, and is parasitic on one of the wrasses 

 (Acantholabrus exoleta) always fastening at the same spot, 

 near the eye. Male and female are usually found together. 



One species, about an inch long, and of cylindrical form, 

 very narrow for its length, is Conilera cylindracea. This 

 one attacks the whiting and bass. 



Two very common species of large size that is, from 

 one to one and a half inches long are Idotea tricuspidata 

 and Idotea linearis, the latter of peculiar centipedelike 

 form. 



These are abundant on sandy shores, and are constantly

taken in the shrimp net. They swim freely at night, and 

 are invariably part of the spoils of the tow net. 



Some are of resplendent colours. The little Dyamene 

 rubra and others are very beautiful. Some are bright 

 scarlet, some blue, others variegated red and white, while 

 their shells are delicately sculptured. 



Eurydice pulchra, as its name implies, is a beautiful 

 form, cream-coloured, with black dots. This little fellow 

 often sticks to the skin of bathers and bites them severely. 

 Tt is about a quarter of an inch long.
