The specimens from Oyster Bay, Tasmania, are typical 
examples of the species, about 50mm. in diameter, dark 
purplish in colour, becoming dull green with a purplish cast 
when dry. The specimen from Flinders Island, Bass Strait, 
is 68 mm. in diameter, with the test very pale brownish and 
the spines light olive green, as in H. tuberculata. The short- 
ness of the primaries and the absence of any arcs of pores. 
with more than 7 pairs show it must be referred to H. erythro- 
gramma. I do not feel satisfied, however, that there are 
really four species of AHeliocidarts on the southern and 
western coasts of Australia, as Doderlein affirms in his recent 
revision of the genus,! but I think it quite possible that these 
four forms will prove to be either a single species or perhaps. 
two. I may here protest against Doderlein’s action in 
putting the Peruvian Echinoid, Cenocentrotus gibbosus, into 
Heliocidaris. The differences in ambulacra, abactinal system, 
coronal plates and spines far outweigh the single resemblance 
in globiferous pedicellariz. If the latter is such a weighty 
character, the species ought to be put in the family Temno- 
pleuride, for the globiferous pedicellarie are surprisingly 
similar to those of Salmacis and Temnopleurus/ On the 
other hand, I think Déderlein is right in refusing to include 
the Japanese species crassispina in Heliocidaris. It is better 
left in Strongylocentrotus, if one is unwilling to recognise the 
genus Anthocidaris for its reception. Four specimens.
