that Fis her was right in referring this species to the genus Nec- 
tria. I would rather join H. L. Clark in holding that it might be 
made the type of a new genus between Mediaster and Nectria 
(H. L. Clark. ‘‘Endeavour” Echinoderms, p. 43).

One specimen, (R 65— 67 mm), dredged off Cuvier Isl. in a 
depth of 20 fms., was presented to me by Captain Bo 11 on s. It 
agrees completely with the description of spe- 
cimens from the Kermadec Islands given by 
Prof. Ben ham, and with specimens from the 
Kermadecs which I have received from Mr. W. 
R.B. Oliver. I have nothing to add to Ben- 
ham’s description, except the observation that 
the pedicellariæ are sometimes, through rarely, 
three valved (Fig. 10). 
Considering how few the Echinoderms com- 
mon to New Zealand and the Kermadec Islands 
are, the finding of this sea-star in New Zea¬ 
land seas is of no small zoogeographical interesr.
