It is very common, large, and beautiful in St. Francis 
Island, where //. tramosericus, Martyn, is very rare and small. 
I did not take it anywhere in Western Australia. Mr. Hedley 
in “The Marine Fauna of Queensland,” in the Australasian 
Association for the Advancement of Science, 1909, p. 355, 
does not include either of these species, nor in his Addendum, 
p. 809. It would seem, therefore, to be restricted to Tas- 
mania and the southern shore of Australia.

I think Tate and May were right in regarding P. chap- 
mani, Tenison-Woods, as conspecific with P. stelleformis, 
Reeve; but the two types are so unlike that the former may 
well be regarded as a good variety of the latter. 
Taken at Rosetta Head, Encounter Bay (Tate), Tyringa 
Beach, Venus Bay, numerous and foliaceous but small, and 
Fowler Bay on the west coast; and on St. Francis Island up. 
to 27 mm. by 20 mm. byg#’5 mm.
