Paul, I think you may be right. Wilson himself on page 28 under damicornis
says that figs 3a and b may not be the same species.
I have only one immature off-white damicornis from NSW. It has an open
siphonal canal and appears to be the more uncommon species.
Although Wilson does not list axicornis, I think it is found throughout the
Indo-Pacifc. Cernohorsky Vol 1 Fig 154 says South Africa to Japan and
Queensland. "Eastern Arabia" fig 453 is a good picture. They mention that
the siphonal canal is nearly closed. I have five with such a near-closed
canal; two from Queensland, and three from the Philippines. However, two of
the five, both from the Philippines, appear quite different from the other
three: the width of the spines is greater than the height, and one of those
has bifurcated spines
I hope someone with more definite information joins the discussion
