 M. De  Blainville.  It  can  scarcely be  a Beluga. 
 T h e   exte rnal  figure  o f  this  animal  greatly  resembles  
 th e Hyperoodon,  and  it   agrees  in  the  hinder  position  of  
 the  b lower;  b u t  the  large  size  o f  th e  pectoral,  and  the  
 absence  o f  the  dorsal,  prevent  it  being  regarded  as  a   species  
 o f that  genus.

 D uring the time the Pla tes have been engraving, and the  
 tex t printing,  the  following  new  materials have  come  into  
 ray  hands, which  I   th in k   may  be  a  useful  addition  lo  the  
 knowledge  o f these  difficult  animals. 
 From  the  examination  I  have  been  able  to  make  of  
 the  baleen  o f  Balænoptera  rostrata,  and  o f  different  
 masses  o f  small  blades  of Ba læ n a   australis,  it would  a p pear  
 as  i f   th ere  was,  a t  least,  in  those  two  species,  two  
 series  o f  Baleen  on  each  side  of  the  palate ;  the  external  
 series being  formed  o f  large  triangular blades  placed  a t  a  
 certain  distant  apart,  and  the  internal,  in  Balænoptera  
 rostrata, iotrüQá o f smaller, m uch thinner, triangular pieces,  
 placed  much  closer  together  and  forming  a  very  dense  
 screening  ap p a ra tu s;  and  in  Balæna  australis, ihamnQx  
 series  is  formed  of  numerous  separate  narrow  strips  of  
 Whalebone, each  ending  in  a  pencil  of  hairs, which  vary  
 in  size  from  th a t  o f  small  twine  to  that  of  tape,  half  an  
 inch w id e ;  these  are  placed  behind  the  others,  aud  gradually  
 increase  in  size  from  the  innermost,  to  the  broad  ex terna 
 l  series. 
 Th e   Baleen  or  Whalebone,  has  generally  been  considered  
 as  the  teeth  of  the  wh a le ;  but  this  must  be  a  
 mistake,  for Professor E sch ric h t has  shown  th a t  the  fcetus  
 o f  Megaptera  Boops  [Banish  Trans.  1845,  xi.  t.  4),  has 
 numerous  teeth  on  the  edge  o f  the  jaiv,  though  they  are  
 never  developed.  I  am  inclined  to  regard  the  Baleen  as a  
 peculia r  development  o f  hair  in  the  palates  o f  these  animals, 
   and  somewhat  analogous  to  the  hair  found  in  the  
 palates  o f th e   genus  Lepus. 
 T h e  Baleen or W halebone, affords good characters for  the  
 separation  o f this  family  into  sections. 
 The  Whalebone  o f  the  smooth-bodied  whales  without  
 any  back  fins,  is  elongate, much  longer  than  broad  a t  the  
 base,  and  gradually  attenuated,  and  edged with  a   fringe  of  
 equal,  lengthened,  fine,  soft bristles.  T h e  Baleen  is in te rnally  
 formed  of a thin  layer  o f  fibres  covered  on  each  side  
 with  a  thick  coat  o f  ‘  enamel,’  when  dry  and  out  o f  the  
 whale  they  are  flat.  T h e  Whalebone of the  plaited  bellied  
 whale with  a  hunch  (Megaptera) or a   dorsal  fin  (Balmnop-  
 tera), is short, broad, triangular, not much longer tlian broad  
 at  the  base,  and  rapidly  attenuated,  and  is  edged with  a  
 series  (sometimes, ra the r crowded)  o f elongate rigid unequal  
 bristles  like fibres, which  become  much  thicker  and  more  
 n g id  near and  a t th e   tip,  the Baleen is intenially  formed  of  
 one  or two  layers  o f  thick fibres,  covered  on each side witli  
 a  thin  layer  o f enamel,  and  when  dry  and  out  o f the  palate  
 they  are  curled  up  and  somewhat spirally  twisted. 
 The Baleen  o f the  BaUence is alone called  Whalebone (or  
 ra th e r  Whale-Jin, as it is usually called) in  commerce.  Tlie  
 Baleen of the other genera o fth is family is called Finner-Jin 
 or  Hnmphac k-fin.  The  wholesale  dealers  in  Baleen,  in  
 t h e ‘London Directory,’ are  called  Whale-Jin Merchants,  
 and whalebone  occurs  under the  name  o f Whale-fin  in  the  
 Price-cun-ent.  In  t h e ‘L o ndonNewP rice-curreiit’  for  1843,  
 the  S outh  Sea  Whale-Jin  varied  during  th a t  year  from  
 ¿6200  to  ¿6305  per  ton,  aud  there  is  no  price  named  for  
 Greenland Whale-Jin. 
 B a l -e n a .  T h e  Baleen  or Whalebone, is narrow, elongate,  
 linear,  or  very  gradually  tapering,  fringed  on  the  inner  
 edge with  numerous  fine,  soft,  flexible  fibres  o f  a  nearly  
 uniform  length,  consisting  internally  o f  a   thin  series  of  
 several  series  of fibres, covered  on each side by a  lliick  coat  
 of enamel. 
 Scoresby describes these animals as having a slight beard,  
 consisting o f a   few  scattered white  hairs,  surmounting  the  
 anterior  extremity  of both jaws.—Arct. Regions,  i.  458. 
 The  fins  or bones  of  eacli  series  together,  are  called  a  
 “ side  of  bone,” the largest are  in  the middle,  from whence  
 they gradually diminish away to  nothing a t  each extremity:  
 the  largest  fin  on  the  side  is  called  the “  sample  blade.” 
 Through  the  kindness  o f  Messrs.  Smith  and  Simmonds,  
 and  Mr.  Smith  o f  Messrs.  W.  Westall  &  Co.,  Whale-fin  
 Merchants,  I  have  been  enabled to examine  and  compare  
 numerous  species o f the  received  from  the  different 
 countries,  and  to  compare  their  peculiarities  as  exhibited  
 during  its  preparation. 
 They know  in  the  trade  three  distinc t  kinds.  1.  The  
 Greenland,  from  Greenland,  Davies’  Straits  and  various  
 parts  of the North  Sea, which  is  th e   best.  2.  The  South  
 Sea,  or B la c k   Jish  whale-Jin  brought  by  the  South  Sea  
 Wha ler^  And,  3.  T h e   Noi-lh  West  Coast,  or  American  
 whale-Jin, which was  first  imported  about  five  years  ago,  
 and  at  first  sold  for  a high  price, but  it  has  now fallen,  and  
 is  considered  as  only  a  large  kind  of  South S e a ;  but  from  
 the  examination  I  have  been  able  to make,  I  should  b e lieve  
 th a t  these  three  kinds  are  each  produced  by  very  
 different  species  o f whales. 
 The  Greenland has  the  hair  on  its  edge  generally  stripped  
 off,  and is  clean  and  b right  when  it  is brought h e r e ;  
 but  Ibis may  be  from  the  care  the North  Sea whalers  take  
 in  collecting  and  cleaning  it  (as  described  by   Scoresby,  
 Arctic  Regions,!.  418),  and  the  bones  a reb ro iig h l  home  
 in  bundles  about  100 weight  each.  On  the  other  liand,  
 the North West Coast  and  the  South Sea,  has  the  hair left  
 on  the  edges,  appears  to  be  brought  home  in  bulk,  and  is  
 a,l ways covered with an ashy w hite soft laminar coat, looking  
 like  the  rotted  external  layers  of  the  enamel.  Tliis  coat  
 has  lo  be  scraped  off with  large  knives  before  it  is  used  or  
 prepared,—and  the  surface  after  the  scraping is  not  so  polished  
 and  resplendent  as th a t  of the Greenland “  fins.” 
 The  three  kinds  are  very  different in  shape.  T h e   outer  
 edge  of the GreciiZaiirf is  curved  considerably ;  in  that  of  
 the  Eorlh-west  coast,  it  is  much  more  s traig h t;  and  in  
 that  of  the  South  Sea,  almost  quite  straight.  Figs.  3,  4  
 and  5, in  Plate  I,  represent  the  three  different  kinds  in tlie  
 same  position,  and  on  the  same  scale,  being  one-fouv-  
 teenth  of  the  natural  length  and  breadth.  T h e   fibres  on  
 the  edge  in  the  Greenland and Ma rg in ed  Whales are very  
 tine,  flexible  and  long,  forming  only  a  thin  series;  in  tlie 
 Soulh  Sea,  they  are  ra the r  coarser;  b u t in  tho  North-west  
 Coast, much  thicker  and  co a rser;  quite  brisllv,  an d  much  
 more  so  towards  the  a p e x ;  and  they  are  move  erect,  and  
 form  a   thicker  series. 
 T h e  Whalebone is  boiled for  about  twelve  liours,  to  re n d 
 e r it  soft  before  it   is  divided  into  strips—it then  divides  
 very  easily.  The  smaller pieces, when  softened,  arc  split  
 by a small machine into very narrow strips like bristles,  and  
 used  for  bristles to make brooms, &c.  &c. 
 F o r  every purpose  the Greenland  “ fins ”  are  preferred,  
 and  last  much  longer,  this  is  even  the  case  with  the  
 false  b ristles;  and  they will  alone  do  for  the  finer work,  
 such  as  the  str¡]is  for  platting  for bonnets,  the  platting  lo  
 make  ladies  riding-whips,  or the covering of telescopes and  
 other  tubes ;  the  while  strips  for  these  purposes  being  
 taken  from  pale  longitudinal  lines  on  the  enamel  o f  the  
 Greenland  fins.

 _  The  Baleen  is  very  long,  varying  from  9  to  12  feet,  
 linear,  tapers  very  gradually,  and o f nearly  the  same m oderate  
 thickness  from  end  to  end,  and  covered with  a  po lished  
 grey  or greenish  black  enamel.  The  internal  fibres  
 occupy  a  small  p a ri  o f  the  substance  and  are  o f  a  fine  
 uniform  texture ,  and  are  black ;  while  the  enamel which  
 forms by  far  the  greater  p a rt  of  the  substance  is  generally  
 blackish ;  b u t it is sometimes, especially on the inner side of  
 th e   “ fin,”  p ale r in  longitudinal  stripes.  The  fibres  on  the  
 edge, like  the  internal  fibres  of which  it  is  a  conLiiuialion.  
 are  very  fine  and  black.  T h e   “ fins”  or pieces  ol' Baleen,  
 are flat, or as the merchant calls  them “ kindly,” so lliat they  
 produce  straight  pieces  fit  for  the  better kind  o f  parasols  
 and  umbrellas, &c., when  cu t into  strips. 
 Some  twenty-five  years,  a  ship  arrived with  the  “  fins ”  
 taken  from  one  “   fish,” which was  peculiar  for  all  being  of  
 a yellowish white  colour,  and  for  having  the  fibres  as well  
 as  the  enamel  of  this  pale  colour.  T h ere is  a  single  “   fin ”  
 of this  animal, nearly  9  feet  long,  now in possession  of Mr.  
 Brunies,  (6, Percy  Circus,  Spafields).  I t   agrees  in  every  
 other  respect with  th e   common Greenland Baleen,  so  that  
 probably  the  fish  was  an  albino. 
 A  specimen  o f  tho  Greenland  whale,  41  feet long,  was  
 stranded  in  Caernarvon  Bay,  May  4,  184C,  and  to n ed   
 into Liverpool.

 The  Baleen  is  nearly  as  long  as  the Greenland,  varying  
 from  7  to  12  feet long,  and  is  slender ;  b u t  for  tlie  same  
 length  it is  nearly  twice  as  thick  in  the  substance,  and  it  
 gradually  diminishes  in  thickness  towards  the  ends. 
 The  enamel, when  the  outer  coat  is  removed,  is  not  so  
 polished  as  th a t  o f  the Greenland,  and when  cu t  through,  
 the  centre  fibres  arc  thicker,  tubular,  and  occupy  about  
 4   to  4  o f  tlie  thickness,  much  more  in  proportion  than  
 they  do  on  the Greenland  fins,  and  the  enamel  and  fibre  
 are  coarser in  texture  and much  more  brittle.
