 they  have  the  defect  of  being variously  bent,  and  tapering  
 towards  th e  end,  which, with  th eir  brittleness,  greatly  re duces  
 their  value.

 T ab .  1 , / .   3.  Baleen. 
 T h e  Balcenis about G feet long, elongate triangular, rather  
 rapidly  tapering.to  a   fine  point.  T h e   internal  fibres  are  
 ra th e r  coarse, b u t much  finer  th an   the  former. 
 T here  are  sometimes  imported with  these  Baleen,  a   few  
 yellowish  white  “  fins,”  which  seldom  exceed  2  feet  in  
 length  ;  in  these,  the  fibres  as well  as  the  enamel  is white,  
 they  are  not  so  transpa rent  as  the white Greenland  fins  
 before  referred to, b u t have th e same coarse tex tu re ,  and are  
 b rittle  like  the  b lac k   southern  specimens,  and  as  they  do  
 n ot  take  so  good  a  polish,  they  cannot b e   used for making  
 shavings  for  platting, &c. 
 T h ere  has  lately  been  brought  by  the  South  Sea  ships,  
 several  hundred weight  of a  very small  kind of W halebone,  
 which is implanted in  th e  remains o f the pala te , in  three  or  
 four  series  gradually diminishing in size  tow-avds  the  innermost  
 series j  each piece is  linear,  compressed,  almost J   to 4  
 o f an  inch wide,  rounded  on the  edge,  varying from  o  to  8  
 inche s  in  length,  aud  ending  in  a  tuft  o f  black  hair-like  
 f ib re s ;  in  texture ,  colour,  and  exte rnal  appearance  it  ex ac 
 tly  agrees with  the  Baleen  of th e   Southern Whales, and  
 I   suspect  it  must  form  the  inner  p a rt  o f  the  “  screening  
 a p p a ra tu s” o f th a t  an im al;  an d   if th a t is  the case, the  ex istence  
 of  these  separate  pieces  n ea r  the  middle  o f  the  
 roof  o f  th e  mouth  will  form  a  very peculia r  character in  
 this  kind  of whale.  I   am  further strengthened  in  this  belief 
 by   perceiving  amongst  some  short  pieces  of  “  Southern  
 Whale-fin,” probably forming  the  end  p a rt  of a  side, a t the  
 inner or shorter  or p alatine  edge  o f each blade, two  or  three 
 lion),  the  account  of  fishing  for  the  Cape  Whales  at  
 T able  Bay,  is  placed  under  the M a n a te   or  Sea-Cows,  apparently  
 because  “  Cow  or  female  whale  are  principally  
 taken ! ”  p.  182. 
 In   the Miisetim o f the Bristol Instituiion, Mr. Stutchbnry  
 informs me  there  are  two lower jaws o f the  “  Cape W hale,”  
 one  15  the  other  10  feet long— aud  the  ribs an d   scapula. 
 Mr. Warwick  p repared  the  skeleton  of  the  young  one  
 mentioned in the tex t, and sold it to M. Boissenaux  of Paris. 
 Mr. Warwick  has  kindly  sent me  a   measurement  o f  a  
 female whale  of  this  species  taken  a t  False  Bay  Fishery,  
 said  to  be  full-grown,  and  considered  by  the whalers  as  of

 a  very  detailed  ac count  o f  the  position  of  the  Baleen  in  
 Greenland Whales, [Arct. Reg. i.  457, and ii.  415), does  not  
 mention  anything  of the  kind  in  th a t animal. 
 Th e  Baleen o f th is animal is sometimes called the Whale-  
 fin  o f  the  “ Black Fish,”  the  name th a t  is  sometimes  ap plied 
   to the Physe ter Microps.  I t  may  be th is  species th at  
 Beale  and  other  Souih Sea whalers  refer to under the  name

 M. Schlegel and F . Cuvier,  are much distressed  because  
 in  describing  the D e lphinus  Capensis,  I  wrote  by mistake  
 shortness instead of lengih, [see Faun. Ja p a n , 13; F. Cuvier,  
 Cetac.  147).  Yet, M.  Schlegel  is  liable  to  the  same  mistake. 
   Th u s   in  p.  23,  he  has  evidently written B .  A n ta rc tique  
 for B . Arctique,  and tbe Plates  26,  Balænoptera A n tarctica, 
   though  it  is  th e  same  animal  as  Balæna A n ta rc tica, 
   in  p.  27 ;  but  if such  oversights  are  to  be  couslantiy  
 refeiTed  to, we  should  liave  little  else  to  do,—and  as  to M.  
 F.  Cuvier, Schlegel  has  pointed  out  many  important mistakes  
 in his description  of the Cape W liale.— Ja p . 2.

 Cape,  I  constantly  found  covered  with  Tuhicinella Balæ -

 W h a le  was  seldom or never  so  covered  :  they  occur  p rin cipally  
 on th e   head, where they are  crowded, and b u t rarely  
 on  the  body,  and then  only  single  scattered  ones.”

 T h e  Baleen  of this genus, and  of the hump-back, is short, 
 broad,  triangular,  ra the r longer than  broad  a t  the base,  and  
 edged with  a  series  o f elongate,  unequal,  bristle-like  fibres,  
 which  become much  thicker an d  more rigid  near  the  upper  
 lip.  I t  is  internally  formed  o f  one  or  two  crowded  layers  
 of  thick tubular  fibres,  covered  on  each  side with  a   thin  
 coat  o f  enamel, which  becomes  thinner  and  thinner  near  
 the  edge, where  the  fibres  are  free;  it is  always  twisted,  
 and  is  only  used  to  sp lit  into  false  bristles,  b u t  in  this  
 they  are  inferior  to  the  Soutliern  or  lowest kind  o f Baleen  
 of the Balænæ. 
 These  animals  are  often  called  Razor-backs,  by  the  
 sailors. 
 Balænoptera  sulcata  Jacob,  [Dublin  Journ.  Science,  
 1825,  333.) 
 Dr.  Jacob  attempts  to  prove  th a t Balæna Boops, B . ros-  
 iraia,  B. musculus, and B .ju b a r te s ,  are  b u t  one  spec ie s;  
 and  he has  taken  considerable trouble to bring together the 
 measurements  and  proportions  o f  th e  different  specimens  
 which  have  been  described. 
 H e  gives an outline o f his specimens, and contrasts it “ with  
 an  outline  o f Hunter’s  P ik e d  Whale,  drawm  according  to  
 the measurements  given  by him ;”  and he  observes,  “ that  
 the  proportions  of  th e   body  (of these  two  specimens)  vary  
 in  a remarkable manner, n o t only as  to  the  situation of the  
 umbilicus  and  other  parts,  b u t  in  th e  breadth  of  the  tail,  
 the  length  o f  the  fin  and  arms.  Th is,  however,  is  what  
 should  be  expe cted,  supposing Mr. H u n te r’s  to  have been  
 a  young  animal, because  such  proportional  superiority  in  
 size of the extremities is characteristic o f the  earlier periods  
 o f life.” 
 In   the  following  table  (observes  Dr.  Jacob),  the  first  
 column  contains  the  dimensions  o f  each  p a rt  in  feet  and  
 in c h e s;  the  second, th e   proportion which  each  measurement  
 bears  to  the entire  length o f the  animal, which  is sup  
 posed  to  be  1,000.

 Professor E sch ric h t  o f  Copenhagen,  who  has  devoted  
 much  time  to  th e   study  o f  the  anatomy  and  development  
 of  the Northem  species  o f  this  genus,  and  has  published  
 several papers  in   th e   Danish  language  on  the  subject,  in  
 transa ctions  of the Danish Academy’  for  1845-1846,  has  
 kindly  translated  for me  the  following  passage  in  his  last  
 published  paper,  as the  then  re sult o f his  exam in a tio n s:—  
 “ Of  all  th a t h a s been  communicated in  this chapter,  it  
 appears  to me  to be proved, th a t amongst  the  F in  whales,  
 at  least,  three  different  species  have  their  abode  in  the  
 Northern  S e a s :— 
 T.  I n   the  Group  o f ihe Longimana. 
 ^  1.  The  Greenland  Keporkak.  B .  Boops,  0 .  Fab.  B   
 iongimana,  Rudolphi. 
 I I .  In   th a t  o f  the  Short-handed. 
 2.  The Norwegian  Vaaga  kval, B . minor ;  and 
 3.  The  common great  short-handed,  B .  Boops. 
 T o  be  almost proved  th a t besides  there  exists, 
 4thly.  A  peculiar  large  short-handed  species.  T h e  Ba -  
 lænopterus Muscuhis. 
 And,  at  least,  it  is highly probable, th a t— 
 5thly.  The Greenlandian Kepokartrak  is  the  representative  
 of a particular form :  and  even  that— 
 6lhly.  The Greenlandian  Tikagalik  or Balæna  I'osiratu, 
 O.  F ab,,  may  h e   a  different  species  from  the Norwegian  
 “   Vaagekval." —E sch rich t,  4th Mem.  p. 157.” 
 M. E s ch ric h t  is  now  engaged  in  examining  the  specimens  
 of Balænoptera,  to  be seen  in the  different Museums  
 of N orthern Europe ,  to  attempt  to  settle  the  synonima  of
