These specimens were all taken from the large spines of a 
Sea-urchin (Prionocidaris australis) and as a rule, they were 
more or less hidden in Barnacles (Acorn-shells) growing thereon. 
The species was hitherto known only from the holotype taken 
at the Murray Islands, Torres Strait, ina large sponge. None 
of the present series is quite so large as the original but they 
show little structural divergence. The smallest specimens 
have 6 arms and are clearly reproducing by fission, but the 
adults are symmetrically 5-rayed. All the specimens are dry 
and their colours are dull but the adults have the arms 
pinkish and more or less distinctly banded. The radial 
shields are not of a different colour from the rest of the disk. 
An excellent specific character is a dark band or spot at the 
middle of the larger arm-spines; all these specimens show it. 
Loc.—Eleven miles south-east of Ballina, New South Wales, 
27-29 fathoms. Eleven specimens. 
OPHIACTIS RESILIENS, Lyman. 
Ophiactis resiliens, Lyman, Bull. Mus. Comp. Zool. Harvard,

One of the individuals from off Kingston, South Australia, 
(disk-diameter, 6 mm.) has all the upper arm-plates broken 
into 2 or 3 pieces. The other specimens, with disk-diameters 
of 3.5 and 5.5 mm. respectively, are not peculiar. It may be 
noted, however, that the species has not previously been 
known from west of Bass Strait. Three specimens. 
Locs.—F¥orty miles west of Kingston, South Australia, 30. 
fathoms. 
Off Cape Martin, South Australia, 21 fathoms.
