This is one of the commonest known species of Amphipod, being 

 found on the sea shore of nearly all climates. It has been recorded 

 from the Rio de la Plata, the Atlantic coast of North America from 

 the Bay of Fundy to New Jersey, the Mediterranean, and the Sea of 

 Tiberias. The species occurs in abundance under decaying sea- 

 weeds at high water mark on all the shores of Bermuda. Prof. 

 Verrill obtained large numbers by attracting them to a pan of al- 

 cohol placed on the beach in the night by means of a lantern.
