As I have pointed out in my work on the „Ingolf" Echinoidea 
it seems hardly possible to distinguish the Pacific form from the 
European Echinocardium cordatum, and H. L. Clark has taken the 
decisive step, declaring that „he would be a hardy zoologist who 
would maintain australe as a species distinet from cordatum “. When 
I have retained the name australe here I do not mean to State 
therewith as my definite opinion that the Australian-New Zealand 
form is a distinet species; it is, indeed, only the discontinuous 
distribution which makes me still hesitate in definitely accepting it 
as identical with the European form. That the New Zealand form 
is identical with the Australian seems unquestionable. 
In some of the specimens from Tiri Tiri I have found globiferous 
pedicellariæ such had not hitherto been observed in the Au- 
stralian-New Zealand form. They prove to be quite similar to those 
of the European form. They were mostly found on the labrum, 
sometimes, however, on the aboral side in the posterior interradius, 
always few in number.

Although it is rather undesirable to augment the number of 
species within this perplexing genus, I do not see how to avoid 
establishing a new species for these specimens. Referring them simply 
to the species with which they appear to be the nearest related, 
Br. Oldhami Alcock, would give a zoogeographical result, not war- 
ranted by facts. If it should ultimately turn out that the New Zea¬ 
land form cannot really be kept separate from that species, little 
harm is done by its having provisionally been named separately, 
attention thereby being called to it and further study of it invited. 
It is briefly thus characterized: 
Petals only slightly sunken, the posterior ones rather diverging, 
somewhat shorter than the anterior ones. Frontal ambulaerum slightly 
sunken; posterior end of the test rather sloping. Oral side rounded, 
the plastron being somewhat raised. Labrum prominent, its posterior 
prolongation ending o ff the middle.of the first ambulacral plate. Five
