collection; deposited; on the 5th of April; about fifty capsules or
bags of eggs upon the stems of weeds (fig。 2 B); each capsule
contained about a hundred eggs。 The capsules opened on the 16th of
May; permitting the escape of rotiferous fry (fig。 2; C; D; E); not
in the slightest degree resembling the parent; but presenting
minute nautilus…shaped transparent shells。 These shells rather
hang on than cover the bodies; which have a pair of lobes; around
which vibrate minute cilia in such a manner as to give them an
appearance of rotatory motion。 Under a lens they may be seen
moving about very actively in various positions; but always with
the look of being moved by rapidly turning wheels。 We should have
been glad to witness the next step towards assuming their ultimate
form; but were disappointed; as the embryos died。 Fig。 2 F is the
tongue of a Nassa; from a photograph by Dr。 Kingsley。
Footnotes:
(1) SERTULARIA OPERCULATA and GEMELLARIA LOCICULATA; or any of the
small SERTULARIAE; compared with CRISIAE and CELLULARIAE; are very
good examples。 For a fuller description of these; see Appendix
explaining Plate I。
(2) If any inland reader wishes to see the action of this foot; in
the bivalve Molluscs; let him look at the Common Pond…Mussel
(Anodon Cygneus); which he will find in most stagnant waters; and
see how he burrows with it in the mud; and how; when the water is
drawn off; he walks solemnly into deeper water; leaving a furrow
behind him。
(3) These shells are so common that I have not cared to figure
them。
(4) Plate IX。 Fig。 3; represents both parasites on the dead
Turritella。
(5) A few words on him; and on sea…anemones in general; may be
found in Appendix II。 But full details; accompanied with beautiful
plates; may be found in Mr。 Gosse's work on British sea…anemones
and madrepores; which ought to be in every seaside library。
(6) Handbook to the Marine Aquarium of the Crystal Palace。
(7) An admirable paper on this extraordinary family may be found in
the Zoological Society's Proceedings for July 1858; by Messrs。 S。
P。 Woodward and the late lamented Lucas Barrett。 See also
Quatrefages; I。 82; or Synapta Duvernaei。
(8) Thalassema Neptuni (Forbes' British Star…Fishes; p。 259);
(9) The Londoner may see specimens of them at the Zoological
Gardens and at the Crystal Palace; as also of the rare and
beautiful Sabella; figured in the same plate; and of the
Balanophyllia; or a closely…allied species; from the Mediterranean;
mentioned in p。 109。

(11) Balanophyllia regia; Plate V。 fig。 1。
(12) Amphidotus cordatus。
(13) Echinus miliaris; Plate VII。
(14) See Professor Sedgwick's last edition of the 〃Discourses on
the Studies of Cambridge。〃
(15) Fissurella graeca; Plate X。 fig。 5。
(16) Doris tuberculata and bilineata。
(17) Eolis papi losa。 A Doris and an Eolis; though not of these
species; are figured in Plate X。
(18) Plate III。
(19) Certain Parisian zoologists have done me the honour to hint
that this description was a play of fancy。 I can only answer; that
I saw it with my own eyes in my own aquarium。 I am not; I hope; in
the habit of drawing on my fancy in the presence of infinitely more
marvellous Nature。 Truth is quite strange enough to be interesting
without lies。
(20) Saxicava rugosa; Plate XI。 fig。 2。
(21) Plate VIII。 represents the common Nassa; with the still more
common Littorina littorea; their teeth…studded palates; and the
free swimming young of the Nassa。 (VIDE Appendix。)

(34) But if any young lady; her aquarium having failed; shall (as
dozens do) cast out the same Anacharis into the nearest ditch; she
shall be followed to her grave by the maledictions of all millers
and trout…fishers。 Seriously; this is a wanton act of injury to
the neighbouring streams; which must be carefully guarded against。
As well turn loose queen…wasps to build in your neighbour's banks。
(35) Very highly also; in interest; ranks M。 Quatrefages' 〃Rambles
of a Naturalist〃 (about the Mediterranean and the French Coast);
translated by M。 Otte。
