SEA LILIES, STARFISHES, ETC.—CLARK. 19 
large size (arms nearly 100 mm. long), but show considerable 
diversity of colour. One has 38 arms, the greater part of 
which are light brown, but basally all are heavily shaded with 
purple, the joints in particular being very dark ; there are 35 
cirri with about 54 segments ; they are, at base, dorsally pale 
brown, orally deep purple, but distally the purple becomes 
very gradually dominant until it includes all of both surfaces. 
The second has at least 36 arms (several are missing) which 
are light brown with more or less of a purplish cast ;_ basally 
three of the rays are very deep purple, the other two being 
decidedly lighter; there are more than 30 cirri with 47-53 
segments, light brown at base, but becoming purple distally. 
The third specimen, from off Noosa Head, Queensland, has 
only 29 fawn-coloured arms (dry), with a faint purplish cast, 
the joints distinctly darker than the segments ; there are, in 
marked contrast, 27 dull purple cirri, pale brownish at base 
dorsally (as in the centrodorsal), with 45-47 segments. In 
this dry specimen the IIIBr series is 2 except in one instance 
of 4 (3+4) but in the other specimens it is common to have 
the III Br series 4 (3+4), although 2 seems the usual number. 
The IfBr series, and the IVBr series, when present, are 
invariably 4 (3+4). The only VBr series noted is 2.

This is a small, dry specimen of uniformly pale brown 
colour, with only 22 arms. There are 8 IJBr series, one of 
which is 2, the rest 4 (3-+4); there are 4 IIIBr series, all of 
which are 4 (3+4). The centrodorsal is low, conical, with 
25-30 cirri, the longest having more than 40 segments. P, 
has 27 segments and is relatively large, but is less than 20 mm. 
long. The occurrence of this species near the Capricorn 
Islands is quite to be expected, but nevertheless extends the 
known range of the species far to the south. The present 
specimen is naturally referred to Carpenter’s Antedon multi- 
radiata, but I think A. H. Clark is quite right in regarding 
that species as a synonym of Z. microdiscus. 
Loc.—Thirteen miles north-east of North Reef, Capricorn 
Group, off Port Curtis, Queensland, 70-74 fathoms.
