that his method of work, and the grounds for the rearrangement of the 
genera, are considered by such authorities as Agassiz and Loriol as. 
injudicious and unscientific. The task of the systematist in a land 
without modern books or scientific periodicals is a difficult one, but 
the work has to be done; we have to do our best, and offer our 
apologies if inaccuracies creep in. 
I have to thank Mr. Farquharson for much help and advice con- 
tained in letters in reply to my queries, and for the loan of foreign 
memoirs. 
Although the collection is not very extensive, it adds a few genera 
to our list, and some species new to science. 
A total of twenty-six genera and thirty-one species is recorded. 
Of thirteen species of asterids, belonging to ten genera, there are 
three genera which have not hitherto been recorded from our area— 
viz., Odontaster, Mediaster, and Luadia. 
Of ophiurids there are six genera, each represented by one species ; 
of which one genus (Astrotoma) has not previously been obtained from 
so southern a latitude. 
The echinids are represented by seven species, belonging to five 
genera, of which one genus (Porocidaris) is new to the New Zealand 
fauna. 
Of the five species of holothurians, representing as many genera, 
one species of Molpadia appears to be new to science. 
Amongst the most interesting finds is Odontaster grayi, hitherto 
recorded only from the neighbourhood of Tierra del Fuego—another 
instance of the subantarctic nature of much of our marine fauna. 
The occurrence of a species of Medvaster, closely allied to but not 
identical with M. arcuatus, from the Japanese seas, adds another 
link with the fauna of that region of the Pacific, which is illustrated 
by the gephyrean Hchiurus nove-zealandie, by the hemichordate 
Dolichoglossus otagoensis, and by certain annelids. But species of 
the genus Mediaster also occur in the eastern Pacific off the west coast 
of the American continent, from Vera Cruz, Cocos Island, and Aca- 
pulco. The occurrence, then, of a species in the western Pacific marks 
an important extension of the range of the genus. 
Astrotoma waitei is another interesting connection between the 
species found in the Banda Sea and Sulu Archipelago on the one hand, 
and that found in the Strait of Magellan on the other; while the pre- 
sence of Porocidaris elegans, hitherto recorded from the neighbourhood 
of Sydney and the Philippines, represents still another element in 
our fauna—the tropical one. 
Of the holothurians, two deep-water forms occur, of which Mol- 
padia marenzellert had hitherto only been obtained by the “ Challenger ” 
from our seas. 
Some confusion in the records resulted from accidents happening 
on board the trawler, during heavy weather, as explained by 
Mr. Waite in the ‘“ Introduction.”
