[123] _Physalia pelagica_, of which a representation is given in the
centre of Plate XXVIII. Some naturalists make two or three other
species, but I do not think that their distinctive characters can as

[125] I ought to say that, as usual in these stranded examples, the
tentacles and suckers were so mutilated by washing on the shore, that I

[126] See his _Gatherings in Australasia_, for much interesting
information on both these animals.

[128] _Sarsia tubulosa_; a group is represented of the size of life, in
the lower right-hand corner of Plate XXVIII.
[129] _Æquorea Forbesiana_; this fine species forms the subject of
Plate XXIX.
[130] _Aurelia aurita_, represented (about one-fourth of the natural
size) in Plate XXX. On the extreme right and left are seen the young,
in the stages of _Hydra_, _Strobila_, and _Ephydra_.
[131] _Cydippe pileus_, seen, of the size of life, near the upper
left-hand corner of Plate XXX.
