This animal, which T have thought it necessary to assign to a new 

 genus, appears to have for its nearest neighbours the genera .Auricula 

 and Pedipes. It was found on the wooden piles which support the mole 

 in the Bay of San Carlos, in Chiloe, below the wash of the high water. 

 The mole stands out into the sea, and there is no fresh water near it, 

 save a very little rill which discharges its tiny stream more than fifty 

 yards off.
