XXVIII.  On  Clavagella.    By  W.  J,  Broderip,  Esq.,  Vice-President  of  the  Geological 
and  Zoological  Societies,  F.R.S.,  L.S.,  &;c. 
Communicated  October  14,  1834. 
In  the  fifth  volume  of  the  '  Histoire  Naturelle  des  Animaux  sans  Vert^bres,'  published 
in  1818,  Lamarck  established  the  genus  Clavagella,  placing  it  with  good  judgment 
between  Aspergillum,  Lam.,  and  Fistulana,  Brug.,  and  recorded  four  species,  all  fossil, 
referring  at  the  same  time  to  the  '  Annales  du  Museum,'  where  he  had  described  and 
figured  the  first  of  them  under  the  name  of  Fistulana  echinata.  The  following  is  La- 
marck's definition  of  the  genus. 
"  Vagina  tubulosa,  testacea,  antic^  attenuata  et  aperta,  postice  in  clavam  ovatam,  sub- 
compressam,  tubulis  spiniformihus  echinatam  terminata :  clavd  hinc  valvam  detectam  in 
pariete  fixam  prodiente ;  altera  in  tubo  libera." 
Mr.  George  Sowerby,  whose  attention  had  been  attracted  to  a  recent  specimen  in  the 
British  Museum,  which  he  took  for  an  Aspergillum,  inclosed  in  a  mass  of  stone,  re- 
quested Mr.  Children  to  allow  a  close  inspection  ;  and  that  gentleman,  with  his  usual 
liberality  and  readiness  to  apply  that  part  of  the  national  collection  committed  more 
immediately  to  his  care  to  the  advancement  of  knowledge,  its  true  and  legitimate  use, 
permitted  some  of  the  earthy  part  to  be  scraped  away,  when  Clav.  aperta,  the  first  re- 
corded recent  species,  was  seen  as  it  is  described  and  figured  in  Mr.  Sowerby's  '  Genera 
of  recent  and  fossil  Shells.' 
Mr.  Sowerby's  definition  is  nearly  the  same  as  Lamarck's. 
Upon  the  return  of  Mr.  Samuel  Stutchbury  from  his  voyage  to  some  of  the  islands 
of  the  Australian  and  Polynesian  groups,  Mr.  George  Sowerby,  in  his  appendix  to  the 
catalogue  of  subjects  of  natural  history  brought  home  by  Mr.  Stutchbury,  described 
and  figured,  in  the  year  1827,  a  second  species  under  the  name  of  Clan.  Australis. 
Three  specimens  were  obtained  with  great  difficulty  by  Mr.  Stutchbury,  who  discovered 
them  at  North  Harbour,  Port  Jackson,  in  a  siliceous  grit,  like  that  of  the  coal  measures, 
just  beneath  low- water  mark,  by  their  ejecting  the  water  from  the  opening  of  tbeir  tubes 
with  considerable  force.  The  specimen  figured  by  Mr.  Sowerby  is  in  the  British  Mu- 
seum, and  another  is  in  Mr.  Norris's  collection  at  Manchester. 
Soon  after  the  pubhcation  of  the  latter  species,  Isaac  Lyon  Goldsmid,  Esq.,  became 
possessed  of  a  mass  of  coral  (Astrcsopora,  Blainv.),  part  of  a  collection  which  he  had 
purchased  at  Aix  la  Chapelle.  In  1829  Mr.  Plenry  Stutchbury,  to  whom  Mr.  Goldsmid 
assigned  the  task  of  arranging  this  collection,  observed  an  aperture  which  he  concluded
