Phyllodesmium identification query

Very sorry to bother you with this, as I'm certain that you're more than just a little bit busy.

I thought I had my Okinawan Phyllodesmium spp. figured out but I fear that I'm making a dreadful error in separating P. cryticum and P. hyalinum.  I'd really like to see your descriptions of these in:

Rudman, W.B. (1981b) The anatomy and biology of alcyonarian feeding aeolid opisthobranch molluscs and their development of symbiosis with zooxanthellae. Zoological Journal of the Linnean Society 72: 219-262.

I was certain that I had the above paper in my possession but apparently not.  If you still have copies or partial copies w/ descriptions/comments of the two Phyllodesmium spp., I'd be forever in your debt.

Best regards,

dear Bob,
My reply's a bit late but I thought this was a good way to distinguish the two species . I'll send you a photocopy of the paper you request when I get a chance. Otherwise hopefully this will solve your problems. ... Bill Rudman.
