Eurydice pulchra. — Leach, Lin, Trans., xi, p* 370. — Bate and 

 Westwood, p. 310. 



Taken in pools on the coast. 



Mr. Walker, of Brookfield, near Chester, says that " It 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 unpleas- 

 antly. 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 Hyper ia, which I had taken from 

 a Ehyzostoma, into a small bottle with two Eury dices, the blood- 

 thirsty little brutes attacked him like tigers, and soon sucked his 

 shell clean."
