interradial plates carry a pedicellaria, which is attached in the 
bottom of a sunk furrow in the plate, When open, the jaws of the 
pedicellariæ lie concealed in the sunk furrow; when closed, the 
jaws raise out of the furrow. The jaws have a few coarse teeth in 
the outer part (Figs. 7.b—e). In the middle of each furrow is seen, 
on removal of the pedicellariæ, a pair of narrow, raised ridges on 
which the jaws of the pedicellaria are mowing up and down (Fig. 7.e). 
Quite exceptionally a single or a few pedicellariæ may be found 
also on the aboral side of the disk. 
The young specimen from Halfmoon Bay, Stewart Isl., differs 
from the larger ones mainly in the shorter marginal plates; the 
two endplates are not yet very prominent, though already nearly 
the double size of the other marginal plates. On the oral interradial 
plates only a single pedicellaria has appeared. 
The type specimen of this species is stated by Cray to have 
come from “China”. Since the species has not later on been found 
in Chinese seas, we may well feel justified in assuming that the 
label of the type specimen was incorrect. Farquhar (1898) fur- 
ther States the species to occur at Australia, from where it is 
recorded by Tenison-Woods 1879^)- Since the species has not 
later on been recorded from .Australia, it must be -regarded as 
doubtful whether it really occurs in Australian Seas. The statement 
(Farquhar, 1898) of its occurrence in the Hast Indies evidently 
rests on the faet that ‘^Åstrogonium' crassimanum Mobius is included 
as a synonym of P. pulchellus. But that this is an error appears 
alone from the faet that P. crassimanus carries pedicellariæ on the 
plates of the aboral side of the disk. It agrees herein with the 
Pentagonaster stibarus, recently described by H. L. Clark from 
West Australia; (indeed, I do not see how the latter is to be 
distinguished from P. crassimanus), 
The result then is that Pentagonaster pulchellus is not known 
with certainty to occur outside the New Zealand Seas. Here it 
appears to be fairly common off the South Island and Stewart Is¬ 
land, whereas it is not known to occur farther to the North than 
Napier. According to Farquhar it occurs also at the Chatham 
Islands.
