Abstract

Diagnostic methods in the case of the interesting group
of Pycnogonida have so far altered in the last thirty
vears, that it needs no apology on my part for attempting
a revision of the descriptions of Australian Pycnogonida
published by Professor Haswell in the early eighties.
This revision has been made possible by the courtesy of the
trustees and curator of the Australian Museum, who placed
the holotypes at my disposal, and to whom I tender my
best thanks. I have also to thank Professor S. J. Johnston
of Sydney for the loan of other specimens collected for the
use of his department.
In the following description the specimens from the
Australian Museum are indicated by the collection
number.
It is necessary to state that the holotypes have been
preserved as microscope slides, and while this is a convenient
method of preservation it has its disadvantages
in the case of subsequent examinations. It is sometimes
impossible, for example, to make out with any degree
of certainty the arrangement and structure of the
spines of the ovigers or even of its joints when, as is
often the case, it is tucked under the body of the Pycnogonid
on a microscope slide. Further, while every care
has been taken with the measurements it must be remembered
that the flattening of the specimen necessary in
preparing a microscopic slide, alters very definitely the
relation of breadth to length.
