SEA LILIES, STARFISHES, ETC. — CLAEK. 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 hne 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, 0. marice, 

 A. H. Clark. The differences in the IBr series and in the 

 pinnides, 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 0. marice. 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 synarthiy in the present species and 

 I do not see why it is not a syzygy. If it is a syzygy or a 

 pseudosyzygy, it seems to me the genus is a connecting form 

 with the Zygometridse, 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.
