and th at the last-named naturalists were followed by Dujardin and
Hnpe. I am led to make these remarks from the fact that throughout
the ‘ Eevision of the Echini ’ the mode of spelling which is both
etymologically and historically incorrect is not only adopted, hut is
ascribed to A^alencieimes, to Liitken, and to Verrill, and is, curiously
enough, carried on into tho lately published Eeport on the Echinoidea
collected by the ‘ Challenger ’ Expedition.

The investigations which I have been able to make into the value
of the generic and specific characters of the Laganidæ (Ann. & Mag.
Nat. Hist. (5) xi. p. 130) have led me to the conclusion th at no
valid grounds exist for the generic or suhgeneric separation of
“ Peronella ” from Laganum.
Prince of Wales Channel ; Thursday Island.
This appears to be one of those species around which misappre-
hensions have collected; the earlier and not ungraceful method of
registration which induced De Blainville * to associate with this
species the name^ of the naturalist to whom he owed his specimen
has, no doubt in haste, been regarded by Professor Alexander
Agassizt as indicating Lesson to be the. author of the species.

Strangely enough, De Blainville himself is not free from error in
the matter, for after Lesson’s name he places the words “ Voyage
de rUranie,” a voyage with which Lesson had not the close relation
th a t he had with th at of the ‘ Coquille,’ and in the account of which
no Echinoderms are described or figured.

ASTEEOIDEA.

Port Jackson. The two specimens are very different in appearance
: one has eleven arms, of which none are remarkably smaller
than the re s t; the other, which has five arms left, and appears to
have had six, has one arm much longer than the others, and has
three small subequal arms.
» For the maiority of the Asteroidea I shall give only one reference and
that to Perrier’s ‘ Revision des Stollerides ’ (Paris, 1875), foUowing its pagination
as a separate work.
