 Cornish (' Zoologist,' 1882, p. 118) records six <$ and one ? 

 specimens taken out of soil and seaweed growing on a derelict 

 cask of paraffin picked up at sea, about six miles off Penzance; 

 and again, curiously enough ('Zoologist,' 1884, p. 116), he 

 writes : " I have received from a derelict water-logged 

 barrel of paraffin, which drifted ashore near Newlyn West, 

 four specimens of the Floating Crab, which were all alive 

 when received." Cocks records a specimen from Bar Castle 

 Point, Falmouth, after a storm Oct. 1845, and a mutilated
