I t will be seen, then, th at of the Echinids 19 were found south of
the tropical line, and 11, or 57‘5 per cent., were not found either
by the ‘A le rt’ or ‘ Australian Museum’ collectors within the tropics.
Of the Ophiurids 9 were found south of the line, and only one also
within it, so th at of this class 88-8 per cent, were found only to the
south of the tropics.
AVhen we turn to the lists of the ‘ Alert ’ collections in the ‘ Australian
’ seas and in the western p art of the Indian Ocean, we find a
very different story.
Echinids.—Of the 28 species collected within the tropical seas of
Australia, four only, or 1-1-2 per cent., were found also at Port
Jackson, while no less than 23, or 72 per cent., were found also in
the tropical parts of the western Indian Ocean.

is added a statement of such as are found also north of the
equator, hut within the tropics).

The Asterids tell a not dissimilar story : of the 26 species found
in the intertropical Australian seas, 3 only, or 11-5 per cent., were
found also at Port Jackson, while 8, or 30 per cent., were found also
in the western seas.
Ophiuroidea.—Twenty-nine species were found in the intertropical
Australian se a s; and of these 3, or 10 per cent., were found also at
Port Jackson, while 16, or more than 50 per cent., were found in
the western parts of the Indian Ocean.
I t is useless, in the present condition of our knowledge, to appeal
to the Holothuroidea or the Crinoidea.
