Palmar and palmate membranes

Dear Sabellida workers, 

In front of me I have the Nelson-Smith OECD booklet on fouling serpulids 
open at figure one. Please tell me that the strange asymmetric palmar 
membrane illustrated is a misinterpretation of McIntosh's lithograph (on 
opposite page) and that 'palmar membrane' is merely an (incorrect?) term 
for fusion or webbing of the radiole edges. 

Palmate membrane in sabellids seems to be a more established term. Would I
be right in thinking this would only be used (if it still is) when there is
actually webbing present, rather than fusion of radiole edges?

Finally I would like suggestions as to the owner & nature of the
structure illustrated in fig 67 of 'the pink book.' What is it do you
