Second Appendix. 
When, in the middle of September 1925, the last proofs of the 
above paper were in hånd, notice was received from the Director 
of the Dominion Museum, Wellington, Dr. J. Allan Thomson, 
that recently a number of Echinoderms had been brought to the 
Museum by a local steam-trawler, the “Futurist”, and that four 
species were being sent to me for examination. It was then thought 
preferable to have a note on this new material included in this 
paper, and the printing accordingly was stopped provisionally, until 
the said material could be at hånd. On its arrival, in the middle 
of October, it turned out to represent an addition to the New 
Zealand Echinoderm Fauna of two new, very interesting species. 
It was thus well worth the little delay in the publication of the 
paper. The four species are: 
Spatangus raultispinus n. sp. 
Persephonaster neozelanicus n. sp. 
Psilaster acuminatus Sladen. 
Åstrotoma Waitei Benham. 
The number of species of Echinoderms known from New Zea¬ 
land is thus raised to 121, and the number of endemic forms to 
100. The zoogeographical results arri ved at above are not altered 
by the finding of the two new forms. The Spatangus has, so far 
as known hitherto, no relations nearer than the Hawaiian Islands 
or South Africa, while the new Asteroid has its nearest relations 
among forms known from the Philippine Sea. 
No nearer information was included about locality and depth, 
where these specimens were found. 
Spatangus multispinus n. sp. 
Test 80 mm long, 76 mm wide, 40 mm high. General shape 
of the test broadly oval, scarcely asymmetrical; it is rather flattened, 
rising very gently to about midway between the apical system and 
the hind end. Frontal ambulacrum rather deep. — Petals narrow,
