the neighbouring shore, where they occur under 

 stones well sunk in the earth. The species is 

 common throughout England and Ireland. 



In experimenting how long it could live in fresh- 

 water, I found that one died after eight hours*

Habitat. — This species has been sent to me from 

 Kilwinning by Mr. John Smith, who states that it 

 is moderately common in that neighbourhood, where 

 it occurs under stones which are sunk an inch or 

 two in the sandy soil. He has found it in situations 

 varying from a few feet above sea-level up to an 

 elevation of about 30 feet, and has also met with 

 it two miles inland. It has also been taken near 

 London by Mr. Francis Walker.
