Londoners; it may be worth while to give a few hints as to what
might be done; by anyone whose curiosity has been excited by the
salt…water tanks of the Zoological Gardens and the Crystal Palace。
An hour or two's dredging round the rocks to the eastward; would
probably yield many delicate and brilliant little fishes; Gobies;
brilliant Labri; blue; yellow; and orange; with tiny rabbit mouths;
and powerful protruding teeth; pipe fishes (Syngnathi) (25) with
strange snipe…bills (which they cannot open) and snake…like bodies;
small cuttlefish (Sepiolae) of a white jelly mottled with brilliant
metallic hues; with a ring of suckered arms round their tiny
parrots' beaks; who; put into a jar; will hover and dart in the
water; as the skylark does in air; by rapid winnowings of their
glassy side…fins; while they watch you with bright lizard…eyes; the
whole animal being a combination of the vertebrate and the mollusc;
so utterly fantastic and abnormal; that (had not the family been
amongst the commonest; from the earliest geological epochs) it
would have seemed; to man's deductive intellect; a form almost as
impossible as the mermaid; far more impossible than the sea…
serpent。 These; and perhaps a few handsome sea…slugs and bivalve
shells; you will be pretty sure to find: perhaps a great deal
more。
Meanwhile; without dredging; you may find a good deal on the shore。
In the spring Doris bilineata comes to the rocks in thousands; to
lay its strange white furbelows of spawn upon their overhanging
edges。 Eolides of extraordinary beauty haunt the same spots。 The
great Eolis papillosa; of a delicate French grey; Eolis pellucida
(?) (Plate X。 fig。 4); in which each papilla on the back is
beautifully coloured with a streak of pink; and tipped with iron
blue; and a most fantastical yellow little creature; so covered
with plumes and tentacles that the body is invisible; which I
believe to be the Idalia aspersa of Alder and Hancock。
At the bottom of the rock pools; behind St。 Leonard's baths; may be
found hundreds of the snipe's feather Anemone (Sagartia
troglodytes); of every line; from the common brown and grey snipe's
feather kind; to the white…horned Hesperus; the orange…horned
Aurora; and a rich lilac and crimson variety; which does not seem
to agree with either the Lilacinia or Rubicunda of Gosse。 A more
beautiful living bouquet could hardly be seen; than might be made
of the varieties of this single species; from this one place。
On the outside sands between the end of the Marina and the Martello
tower; you may find; at very low tides; great numbers of a sand…
tube; about three inches long; standing up out of the sand。 I do
not mean the tubes of the Terebella; so common in all sands; which
are somewhat flexible; and have their upper end fringed with a
ragged ring of sandy arms: those I speak of are straight and
stiff; and ending in a point upward。 Draw them out of the sand …
they will offer some resistance … and put them into a vase of
water; you will see the worm inside expand two delicate golden
combs; just like old…fashioned back…hair combs; of a metallic
lustre; which will astonish you。 With these combs the worm seems
to burrow head downward into the sand; but whether he always
remains in that attitude I cannot say。 His name is Pectinaria
Belgica。 He is an Annelid; or true worm; connected with the
Serpulea and Sabellae of which I have spoken already; and holds
himself in his case like them; by hooks and bristles set on each
ring of his body。 In confinement he will probably come out of his
case and die; when you may dissect him at your leisure; and learn a
great deal more about him thereby than (I am sorry to say) I know。
But if you have courage to run out fifteen or twenty miles to the
Diamond; you may find really rare and valuable animals。 There is a
risk; of course; of being blown over to the coast of France; by a
change of wind; there is a risk also of not being able to land at
night on the inhospitable Hastings beach; and of sleeping; as best
you can; on board: but in the long days and settled fine weather
of summer; the trip; in a stout boat; ought to be a safe and a
pleasant one。
On the Diamond you will find many; or most of those gay creatures
which attract your eye in the central row of tanks at the
Zoological Gardens: great twisted masses of Serpulae; (26) those
white tubes of stone; from the mouth of which protrude pairs of
rose…coloured or orange fans; flashing in; quick as light; the
moment that your finger approaches them or your shadow crosses the
water。
You will dredge; too; the twelve…rayed sun…star (Solaster papposa);
with his rich scarlet armour; and more strange; and quite as
beautiful; the bird's foot star (Palmipes membranaceus); which you
may see crawling by its thousand sucking…feet in the Crystal Palace
tanks; a pentagonal webbed bird's foot; of scarlet and orange
shagreen。 With him; most probably; will be a specimen of the great
purple heart…urchin (Spatangus purpureus); clothed in pale lilac
horny spines; and other Echinoderms; for which you must consult
Forbes's 〃British Star…fishes:〃 but perhaps the species among them
which will interest you most; will be the common brittle…star
(Ophiocoma rosula); of which a hundred or so; I can promise; shall
come up at a single haul of the dredge; entwining their long spine…
clad arms in a seemingly inextricable confusion of 〃kaleidoscope〃
patterns (thanks to Mr。 Gosse for the one right epithet); purple
and azure; fawn; brown; green; grey; white and crimson; as if a
whole bed of China…asters should have first come to life; and then
gone mad; and fallen to fighting。 But pick out; one by one;
specimens from the tangled mass; and you will agree that no China…
aster is so fair as this living stone…flower of the deep; with its
daisy…like disc; and fine long prickly arms; which never cease
their graceful serpentine motion; and its colours hardly alike in
any two specimens。 Handle them not; meanwhile; too roughly; lest;
whether modesty or in anger; they begin a desperate course of
gradual suicide; and; breaking off arm after arm piecemeal; fling
them indignantly at their tormentor。 Along with these you will
certainly obtain a few of that fine bivalve; the great Scallop;
which you have seen lying on every fishmonger's counter in
Hastings。 Of these you must pick out those which seem dirtiest and
most overgrown with parasites; and place them carefully in a jar of
salt water; where they may not be rubbed; for they are worth your
examination; not merely for the sake of that ring of gem…like eyes
which borders their 〃cloak;〃 lying along the extreme out edge of
the shell as the valves are half open; but for the sake of the
parasites outside: corallines of exquisite delicacy; Plumulariae
and Sertulariae; dead men's hands (Alcyonia); lumps of white or
orange jelly; which will protrude a thousand star…like polypes; and
the Tubularia indivisa; twisted tubes of fine straw; which ought
already to have puzzled you; for you may pick them up in
considerable masses on the Hastings beach after a south…west gale;
and think long over them before you determine whether the oat…like
stems and spongy roots belong to an animal; or a vegetable。
Animals they are; nevertheless; though even now you will hardly
guess the fact; when you see at the mouth of each tube a little
scarlet flower; connected with the pink pulp which fills the tube。
For a further description of this largest and handsomest of our
Hydroid Polypes; I must refer you to Johnston; or; failing him; to
Landsborough; and go on; to beg you not to despise those pink; or
grey; or white lumps of jelly; which will expand in salt water into
exquisite sea…anemones; of quite different forms from any which we
have found along the rocks。 One o
