The animal fastens pieces of broken shells, small stones, ete., to its 
column, and when retracted looks like a small heap of gravel. The com- 
pound tentacles are not sensitive. Its nearest ally is Metridium muscosum 
Drayton, from New South Wales, which Milne-Edwards and Haime have 
placed in their genus Oulactis. Occasionally some of the lobes of the 
compound tentacles are pink or orange.
