 leaves  of  a  bell-like  figure,  with milk-white  pointed  javelins  at  the  
 infertion  of the  rays which are of a brown,  fpeckled  green;  the ftem  
 marked with  tranfverfe  lines}  rays  three  inches  long.  One of this fort  
 (that is, with leaves of the fibula  fliaped  in  like  manner)  has a yellow  
 fibula;  but  the  ftem  of  the  radius  is  diverfified  by  fouare  compartments, 
   as  in  Fig.  x x i}  rays  two  inches  and  a  half  long  :  A  third  
 has  no  javelins  at  the  infertion,  but  the  bell-like  leaves  with  a  
 whitifh nucleus  in  the  centre, and the ftem of the ray cut  into fquares  
 of the  richeft  fcarlet  intermixed with  green}  rays  three  inches  long.  
 In  Fig.  xxiix.  the  fibula  is  black,  pentagonal,  interfered  by  five  
 white  flips  (of  the  figure of  a  Lens)  running  from  the  ftem  of the  
 ray  to  the  central  nucleus;  the  rays  of  an  olive  green,  ftudded  with  
 dies  of  a  darker  colour.  In  Fig.  xxiv.  the  fibula  confifts  of  five  
 petals  only,  the  outer  edge  of  which  is  a  brown  Cologn-earth,  
 lightning  into  a  yellow  in  the middle;  the  rays  are  diftipguifhed  by  
 two  rowes  of dies,  one  on  each  fide of the  ftem,  the  dies oppofite,  
 and of a dark green;  another with  like  rays  has the  like fibula,  but  
 o f  a  fky-blue  colour;  rarely met With.

 the belly-part o f the  fame with which  it  fticks  to  the  rocks}  it  was  
 of  a  Hefti-colour}  they  are  all  o f  the  fame  fize  I  found  them  on  
 Careg-kilks  near Penzance,  Oftober  8,  1756.  Some  other  little  
 differences  occurred }  but thefe  are  fufficient  to  intimate what diver-  
 fity of colourings and workmanfhip may be met with  in  this  tribe.

 li(h coaft,  is not  lb uncommon on  the  fhores o f Cornwall:  Its  bone  
 is nfed by the  filverfiniths  in polifhing,  and foffietimes admitted  into

 Ek'®h*  * 7 5 7 ;  and  being a  fair  entire ipecimen  of this uncommon  animal,  
 I add  the  following  defcription:  The  body  is  eleven  inches  long,  
 compreffed,  one  inch  and  a half  thick,  fpreading on each  fide  into  
 a  thin,  triangular,  fleftiy  fobftance,  a a,  which  ferve as  fins  in water,  
 and  as  wings  in  air;  the  tail  much  more  obtufe  than  that  of  
 Rondcletius  page  508;  the  head,  c,  is  globular,  one  inch  and  a  
 half  high;  it  had  ten  tentacles,  d  of  various  lengths ;  the  two  
 longed,  e  e,  are  pedunculated,  not  extended  to  their  full  length,  
 their  ftems  round,  and  near  the  extremities  their upper  fide  fpread

 with  tubular  cups  o f  the  lame  fiefhy  fubftanoe  as  the  ftem;  they  
 end  in  certain  nipples  or  tubercles:  the  other  tentacuhx  are  more  
 flat  and  wide;  they  have  one  edge  alfo  full  o f  thefe  nipples,  with  
 a  few  cups  in  the  middle  of  them ;  of  thefe  cups  I  apprehend  the  
 fifh  expands,  and  contracts  the  brim  for  the  reception or emiffion  
 of  the  air,  and  fixing  itfelf  by  fu&ion  to  rocks  or  plants,  as well  
 as  for  laying  faft  hold  of  its  prey:  the  tenfacula are  both  arms  
 and  feelers,  and  by  the membranous  and  tender  ftruefure  of  their  
 tubes, doubtlefs  of moft  acute  fenfe;  by the recurve  figure  in which  
 they  ftiffen'as  the  animal'dies,  they  appear  alfo  to  quicken  the  
 motion  of  fwimming  by  their  alternate  extenfion and  contraction.  
 This  fifh  contains  inwardly  a  certain  juice  fo  black  in  feme  of  the  
 kind,  that  it  may  be  ufed  for  inke.  Pliny  thinks  it  the  blood o f  
 the  aniinal,  Blit  by  later  difcoveries  it  appears  to  be  an  excremen-  
 titiousv fecretiori  from  the  aliment,  which  from  its  own  repofitory  
 the  animal  fheeff when  under  the  apprehenfion  of  any imminent  
 danger,  and  thereby  difcolouring  the  water,  frequently  conceals  
 himfelf  from  his  enemy.  The Athenians  held  this  fifh very cheap,  
 but now  the  fmaller  fort  efpecially  is  much  coveted,  and by  feme  
 placed  among  the  greateft  delicacies  of  the  table,  when  feafoned  
 (kilfully  with  oil  or  butter,  pepper  and  wine;  but  Rondcletius  
 thinks  them  hard of  digeftion,  lib.  xvn.  chap.  v.  This  ipecimen  
 had  one  bone  iii  the  middle  like  the  blade  o f  a dagger  (therefore  
 called  its 'filadidlusj ;  its  ufe  is  to  ftiffen  the  foft and  lax  flefh o f the  
 body; '  it  had plenty  of ink,  and was  found on  the lands of Mount’s

 FROM  the  ieaft  and  feemingly moft  imperfedf lea-animals,  but  
 equally  neceflary  in  their  degree,  we  are gradually  arrived  to  
 the moft  perfect  inhabitants  o f the  ocean. 
 And  if   I  were  here  t»  let  fbrtli  an  orderly  arrangement  of  fifties  
 in  general,  I  Ihould  trace  them  through  the  feveral  dalles  into  
 which  nature  has  forted  them,  by  lungs  and  gills,  by  bones  and  
 cartilages',  by  the number,  lhape  and  place  of  fins  and  teeth,  by  
 the  fcaly  armour  of  Ibnie,  and  by  the mucilaginous  ftnooth coating  
 of others;  but  as my plan  is  local  and  more  confined,  I  find myfelf  
 only  engaged  to  purfue  the  finny  race  through  the waters  of  this
