ACKNOWLEDGEMENTS
I would particularly like to thank Loisette Marsh
(WAM), who first suggested this project and who
graciously made the WAM specimens available to
me for study. Mark J. Grygier was also an
encouragement to begin and continue the work.
S.D. Cairns
I would like to thank the following people who
have generously loaned me specimens used in this
study: Phil Alderslade (NTM), Karin Sindemark
(SMNH), Timothy Stranks (NMV), Wolfgang
Zeidler (SAM), and Penny Berents (AMS).
The scanning electron photomicrographs were
taken in the SEM Laboratory of the National
Museum of Natural History.
