 " an immature Pleurobranchus, very likely P. plumula, Montagu ; but 

 the dorsal skin has been torn off. The species cannot be identified."

Sir Charles Eliot remarks, " The body of an ^olid which has lost 

 all but its papillae and is otherwise in poor preservation. It is not 

 possible to determine even the genus."
