It is a common species on all the western coast of 

 England, having been taken in Cornwall, and along the 

 coast of Devonshire, Dorsetshire, Hampshire, and Sussex. 

 Dr. Leach mentions it being taken under stones at low 

 tide, but those which I have obtained have been from deep 

 water. I have dredged them in Swanage Bay, Dorset- 

 shire ; but the finest specimens I ever saw, I procured from 

 prawn and lobster pots at Bognor, in September, 1842. 

 It is worthy of remark, that amongst twenty or thirty 

 specimens, I found only one female, a dead and mutilated 

 one. It would appear from Mr. Thompson's Catalogue 

 to be widely distributed on the coasts of Ireland, although 

 occurring in small numbers. 



The different species of this genus are very widely dis- 

 tributed. They inhabit the Mediterranean, the Red Sea, 

 the East Indies, and other parts of the coast of Asia, 

 Australia, and both the eastern and western coasts of South 

 America.
