SEA LILIES, STARFISHES, ETC.—CLARK. 35 
r=35 mm. and br=40 mm. Comparison of these two 
specimens brings out the interesting fact that there is almost 
no increase, during growth, in the number of the big paxilli- 
form ossicles; in the small specimen there are 7 in the 
midradial line of each arm, and about 8 in each interradial 
area ; the whole dorsal surface is almost completely covered 
by them. In the big specimen, there are only 7 or 8 well 
formed ones on each radial line, while in the interradial areas 
the number is not more than 8 or 10; along the sides of the 
basal part of each ray new ones have formed, but they are 
smaller than the others and merge into the ordinary abactinal 
plates. But in the large specimen, the ossicles are widely 
separated from each other, the abactinal skeleton and papular 
areas being fully exposed. In the small specimen, there are 
only 12 marginal plates in each series on each ray; they 
are closely joined with no trace of intermarginal papule. 
Even in the large specimen, however, I fail to find any 
intermarginal papule.

NECTRIA OCELLIFERA (Lamarck).

These five specimens are probably from the same lot as those 
in the Western Australian Museum at Perth, by means of 
which it was possible to clear up the difference between 
N. ocellata and N. ocellifera.1 There can be no doubt, I 
think, that the two species are perfectly distinct, and the 
“* Endeavour ” collections seem to confirm the view that their 
areas of distribution do not overlap. The specimens of JN. 
ocellifera at hand are all small, having R only about 40 mm.

Australia.
