tiring tide, where it swims about with the utmost celerity. 

 It is not difficult to keep it alive in confinement, Slabber 

 having kept one for nine days in the month of August. 

 It occurs on the coast of Devonshire, where it was taken 

 at Bantham by Dr. Leach, and in South Wales by our- 

 selves, on Loughor Marsh, and on a cuttlefish shell on 

 the beach in Caswell Bay, and Mr. W. Thompson 

 obtained it from Larne. Van Beneden states that he 

 only found it in summer ; it was, however, taken at 

 Carrickfergus, by Mr. Hyndman, on the 17th of March, 

 1840. 



M. Hesse has found it burrowing in sand on the coast 

 of Britanny. The Rev. A. M. Norman has sent it to us 

 from the coast of Northumberland and Durham, and 

 Mr. Walker of Brookfield, near Cheshire, writes us that 

 " Corophium longicorne and Eurydice pulchra are the com- 

 monest Crustacea in the Dee, at least at Bagillt, where 

 his observations have been made. " The latter," he says, 

 " is a most savage little beast. If you are a moment 

 still in the water while bathing, dozens will fasten upon 

 you and nip most unpleasantly. I have had to jump into 

 the water again after coming out from bathing and splash 

 violently to get rid of the hosts that had stuck to me 

 while clinging to the side of the boat preparatory to 

 getting in. They continue to bite after you are out of 

 the water. I once put a wretched Hyperia which I 

 had taken from a Rhyzostoma, into a small bottle with 

 two Eury dices ; the bloodthirsty little brutes attacked 

 him at once like tigers, and soon sucked his shell clean."
