Goniocidaris umbraculum (Hutton). In the “New Zealand Journ. 
of Sci. & Technology” Vol. VII. 3 . p. 189 (Sept. 1924) Maxwell 
Young has published a note on the “Occurrence of the Echino- 
derm Goniocidaris umbraculum Hutton” in which he 
records numerous specimens from E. N. E. off Otago 
Heads, 60 fathoms. His statement that “the species 
has previously been recorded from Foveaux Strait 
and Stewart Island” seems to show that he has not 
seen my report on the New Zealand Echinoidea, 
in which the species is recorded also from the Cook 
Strait (p. 146). Had he seen that report, he would 
probably also have avoided turning his specimens 
upside down, as he has evidently done, since he States 
that the spines “on top are of the usual shape, but 
the ones on the underside are dilated at the tip so 
as to form a concave terminal disc”. 
Echinocyamus polyporus Mrtsn. In my description 
of this species I was unable to give any information 
about the characters of the spines and pedicellariæ, 
all my specimens being naked tests. Professor Ben¬ 
ham having since then sent me a pair of alcoholic 
specimens, I can here supply some of the information

pediceiiana of spines are not very characteristic. The pri- 
Echinocyamus 
polyporus. mary spines are clubshaped, very nearly smooth, ca. 
0.5 mm long. Those near the peristome and the 
periproct are elongated, c. I.5 mm long, siender, slightly curved- 
The miliary spines hive a smooth crown, or there may be a faint 
indication of serrations. — Of the pedicellariæ I have only suc- 
ceeded in finding the tridentate form (Fig. 67); the valves are narrow, 
the blade closed in the lower half; the edge of the outer, open 
part faintly dentate.
