with the shape of arms as in angustus. These two specimens, in 
faet, show the characters of both dilatatiis and angustus thus inter- 
rningled that we are forced to recognize both forms as one and 
the same species. This result is also thus far satisfactory, as it 
would seem beforehand somewhat remarkable that two species of 
this comparatively rare form should oceur together at the New 
Zealand coasts. The variation in regard to the shape of its arms 
offers an interesting parallel to what obtains in Pentagonaster pul- 
chellus. 
De Loriol points out the existence of glassy warts surrounded 
by the usual grains on the outer marginal plates. I find these glassy 
warts likewise in my specimens, not alone on the marginals but 
also on the outer plates of the middorsal series. — Koehler 
describes and figures some larger round holes in the madreporite 
in one of his specimens. I do not see anything of the sort in my 
specimens and might venture to suggest that these holes are not 
a normal feature of the madreporite. 
This species is not known outside New Zealand, and on the 
New Zealand coast it is hitherto known with certainty only from 
the locality given here and the two localities mentioned by Koehler, 
viz. Te Onepoto (Taylor’s mistake, near Lyttelton), and “Wangawai”, 
which would appear, according to the kind information of Professor 
Benham, to be a misprint for Wanganui, on the West coast of 
the South Islands.
