Two new Australian Pycnogonida

There is no doubt that the interest shown in the Antarctic forms of Pycnogonida, and the problems raised by the study of this remarkable group of animals in the Southern Polar Regions, have made it advisable, or even necessary, that detailed attention and study should be given to the Australian forms. However, no work has been published on the Pycnogonida of the Australian Coast since Professor Haswell's paper in 1884, except a short paper written by myself on Halosoma haswelli.
I have, therefore, no hesitation in presenting a description of two new Australian forms, more especially as they represent genera not previously described from this part of the world, and they distinctly help in settling certain problems of distribution, especially in relation to the genusi Ammothea. These new species belong to the genera Pycnogonum, Brunn., and Ammothea, Leach.
