Patria: Egypt (Savigny). This species seems to be widely 

 distributed on the. sea-shores of all the countries around the 

 Mediterranean Sea; it burrows in the sand on the beaches to a 

 depth of few centim. and seems to come up in the evening; in 

 such manner I have collected many specimens at Pisa Marina in 

 Italy by turning the sand over. I can also refer to my remarks 

 1. c. of Tylos capensis Krauss that Prof. VanhOppen has found 

 at the Cape under similar circumstances.
