       BALANOPHYLLAEA REGIA。                   PL。 V。 FIG。 1。 

       Another    species    of  British   madrepore�察    �found    by   Mr。   Gosse    at 

Ilfracombe�察�and by Mr。 Kingsley at Lundy Island。              It is smaller    than O。 

Smithii�察�of a very bright colour�察�and always covers the              upper part of its 

bony skeleton�察�in which the plates are          differently arranged from those of 

the smaller species。      Fig。 1    shows the tentacles expanded in an unusual 

degree�察�1 A�察�animal       contracted�察�1 B�察�the coral�察�1 C�察�a tentacle enlarged。 



    PLATE VI。 



     CORALS AND SEA ANEMONES。 

    ACTINIA MESEMBRYANTHEMUM。                         PL。 VI。 FIG。 1 A。 

       This common species is more frequently met with than many others�察�

because   it   prefers   shallow   water�察  �and   often   lives   high   up   among rocks 

which are only covered by the sea at very high tide�察�so that              the creature 

can�察�if it will�察�spend but a   short portion of its time         immersed。       When 

uncovered by the tide�察�it gathers up its leathery            tunic�察�and presents the 

appearance      of  fig。  1  A。   When      under   water    it  may    often  be   seen 

expanding its flower´like disk and moving its             feelers in search of food。 

These feelers have a certain power of          adhesion�察�and any not too vigorous 

animals     which    they  touch   are   easily    drawn    towards    the  centre   and 

swallowed。       Around     the   margin    of   the   tunic  are  seen   peeping    out 

between the tentacles certain        bright blue globules looking very like eyes�察�

but whose purpose is        not exactly ascertained。      Fig。 1 represents the disk 

only partially     expanded。 

       BUNODES CRASSICORNIS。                 PL。 VI。 FIG。 2。 

       This   genus   of  Actinioid    zoophytes    is  distinguished    from   Actinia 

proper   by   the   tubercles   or   warts   which   stud   the   outer   covering   of the 

animal。     In B。 gemmacea these warts are arranged symmetrically�察               �so as 

to give a peculiarly jewelled appearance to the body。             Being     of a large 

size�察  �the  tentacles   of  B。   crassicornis   exhibit   in  great   perfection    the

them。

    NASSA RETICULATA。               PL。 VIII。 fig。 2�察�A�察�B�察�C�察�D�察�E�察�F 

       A  VERY      active  Mollusc�察   �given   here   chiefly   on  account    of  the 

opportunity   afforded   by   the   birth   of   young   fry   in   Mr。   Lloyd's tanks。 

The NASSA feeds on small animalcules�察�for which�察�in               aquaria�察�it may be 

seen routing among the sand and stones�察          �sometimes burying itself among 

them so as only to show its caudal         tube moving along between them。           A 

pair of Nassae in Mr。 Lloyd's         collection�察�deposited�察�on the 5th of April�察�

about fifty capsules or      bags of eggs upon the stems of weeds ��fig。 2 B���察�

each capsule      contained about a hundred eggs。          The capsules opened on 

the 16th of     May�察�permitting the escape of rotiferous fry ��fig。 2�察�C�察�D�察�E���察�

not    in the slightest degree resembling the parent�察�but presenting           minute 

nautilus´shaped   transparent      shells。  These     shells  rather  hang    on   than 

cover    the  bodies�察  �which   have   a  pair  of  lobes�察 �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�察 �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�察   �but  were   disappointed�察   �as  the 

embryos died。      Fig。 2 F is the     tongue of a Nassa�察�from a photograph by 

Dr。 Kingsley。
