but less conspicuous because of their duil colour, or because they 
live wholly concealed among the leaves of the alga, are Cucumaria 
brevidentis (the typical form), Cuc. leoninoides, Åmphiura magellanica, 
præfecta, Ophiomyxa brevirima, Henricia lukinsii, Trochodota dune- 
dinensis, various worms, e. g. Steggoa brevicornis, Nereis australis, 
N. Mortenseni, Podarke angustifrons, Lumbriconereis magelhaensis, 
Polycirrus kerguelensis, several Syllids.Also various small Crusta- 
ceans and some Actinians (Edwardsia tricolor, Condylanthus auck- 
landicus)}) Evidently, this luxurious growth of Melobesia thus offers 
a favourite place — perhaps no less a hiding place than a feeding 
ground — for a great variety of smaller animals. However, hardly 
any of these forms is exclusively bound to the Melobesia-locality, 
not being so specially adopted to life among the Melobesia-leaves 
as to be unable to thrive in other localities. 
The Echinoderm fauna of Macquarie Island is still very in^ 
sufficiently known; only as regards the Asteroids we have got 
some better information through the researches carried out there in 
1913 by Mr. A. Ham il ton as member of a research party left 
on the island by Sir Douglas Mawson, the leader of the Au- 
stralasian Antarctic Expedition. In his Report on the Asteroidea of 
the said expedition R. Koehler records the following 6 species of 
sea-stars from Macquarie Island: 
Sporasterias antarctica (Liitken) 
Parastichaster directus Koehler 
— Mawsoni Koehler. 
Parastichaster sphærulatus Koehler 
Asterina Hamiltoni Koehler 
Cycethra macquariensis Koehler. 
Ben ham (‘‘Subantarctic Islands of New Zealand”, p. 302) has 
recorded also Calvasterias (Stichaster) Suteri from Macquarie Island, 
likewise collected by Mr. Ham il ton during a previous visit to 
the island. According to Koehler (Op. cit.) this is probably a 
mistaken idenlification of the species described by him as Parastich¬ 
aster mawsoni. — While it appears that no Ophiurids were col¬ 
lected at the Macquarie Island by Mr. Ham il ton at least none
