SEA LILIES, STARFISHES, ETC.—CLARK. 49 
the granulation is finer than in other Stellasters and the 
marginal spines are gone ; the abactinal spines too are much 
reduced in number and even the actinal, adambulacral spine 
is somewhat smaller than in other species. If Ogmaster is not 
a close relative of Stellaster, it is hard to see what its correct 
position is. 
Loc.—Between Geraldton and Cape Naturaliste, Western 
Australia. Two specimens.

This is an excellent series, with R ranging from 40 to 120 
mm., and the vertical diameter of the disk from 12 to 50 mm. 
The growth changes are well shown, as well as considerable 
individual diversity. Twenty-four specimens.

Off the Queensland coast. 
Twenty miles north-north-east of Double Island Point, 
Queensland, 30 fathoms. 
Thirteen miles north by west of Double Island Point,

OREASTER AUSTRALIS, Liitken. 
Oreaster australis, Liitken, Vid. Med., 1871, pp. 252, 263. 
These are all dry adults, illustrating not only the great 
individual diversity in abactinal spines, but also the diversity 
caused by differences in collapse and contraction when drying.
