SEA LILIES, STARFISHES, ETC.—CLARK. 21 
Colour, of the single dry specimen, purple and white ; 
centrodorsal, dorsal surface of brachials and of pinnules, and 
scattered spots elsewhere, white or whitish ; IBr series dirty 
whitish with a purple tinge ; IIBr series, a few of the lowest 
brachials, a conspicuous line along each side of each arm, and 
oral surface of pinnules, at least on basal portion, more or less 
deep purple. 
This very handsome species was at first referred to Zygo- 
metra on account of the syzygy in the radial axillary. Mr. 
A. H. Clark kindly suggested comparing it with Calometra and 
the examination of the pinnules indicated relationship to that 
genus. I think there can be no doubt, however, that this 
specimen is a representative of the recently described genus 
Oreometra and it is quite near the type-species, O. marie, 
A. H. Clark. The differences in the [Br series and in the 
pinnules, however, forbid referring it to that species. The 
occurrence of a syzygy between brachials 2 and 3 is note- 
worthy ; Mr. Clark says nothing about syzygies in either one 
of his two published descriptions of O. marie. He does say, 
however, that the connection between IBr 1 and 2 is ‘“‘an 
exceedingly close synarthry,” while I have been convinced 
after a careful examination of the distal face of IBr 1 that 
the joint is certainly not a synarthry in the present species and 
I do not see why it is not a syzygy. If it is a syzygy ora 
pseudosyzygy, it seems to me the genus is a connecting form 
with the Zygometride, if not actually a member of that 
family. The pinnules obviously count against any such view. 
The cirri I have not seen.

This is a fine adult individual with 28 arms; it had about 
25 cirri, the longest with 45 segments. The colour (dry) is 
uniformly brownish-white. The species was not previously 
known from south of Port Curtis, Queensland. 
Loc.—Thirteen miles north by west of Double Island Point, 
Queensland, 25-26 fathoms.
