NOTES ON SOME OF THE FOREGOING SPECIES 
OF 
ae eae ALIN, CE LIN £. 
PHYLLACANTHUS ANULIFERA. 
This species, in itS numerous varieties, is found to be very 
plentiful a little north of Brisbane, especially at Port Denison, 
where one of our Assistants, Mr. Antex. Morton, dredged it in 
quantity, in Glocester Passage and other parts adjacent to 
Bowen, in from 5 to 15 fathoms. It is a gregarious species, and 
exhibits much variation in the form and coloration of its spines. 
Many specimens in various stages of growth are exhibited. 
PHYLLACANTHUS DUBIA. 
It is very doubtful if this species is found on the South-East 
Coast, the specimens reported by Mr. Trentson- Woops from 
Tasmania and Bass’ Straits, probably belong to the next species, 
P. parvispina. The specimens exhibited agree very well with 
the figures of P. dubia in A. AGasstz, Revision of the Echini, 
but not with those from Port Jackson (P. parvispina, T.-W..,) 
I believe P. dubia is only found on the northern parts of 
Australia, where, like the Port Jackson species, it frequents the 
rocky parts of the coasts and may be taken at low tides; it 
appears to be rare, z.e., if the variety found in Port Jackson 
is to be considered to be a good species. 
PHYLLACANTHUS PARVISPINA, 7-W. 
P. tenuispina, Tentson- Woops, MSS. 
This is the representative of P. dubia of the North Coast. 
Mr. TEentson- W oops has (Proce. Linn. Soe. of N.S. W., iv., p. 286) 
already pointed out the differences in those from Port Jackson, 
on which he has founded this new species. In P. parvispina the 
test is frequently wider than high, the distance between the poles 
being /ess than the diameter, this may be seen both in young and 
adult specimens, the spines are also proportionately shorter. 
It is strictly a litoral species, but can scarcely be called 
gregarious, frequenting during the summer months the rocks 
and reefs just below low-tide mark, retiring into deeper water
