o f 0 . Fabricius is in ten d ed for th is species, as it is called
kepokak by the Greenlanders. I f this is th e case, the description
fi
o f th e form and position o f th e dorsal fin is not
correct.
Professor E sch ric h t observes, « this animal is always in-
lested with Diadem a Bah en a rum , and with a species of
Otion, which he regards as new, while the Cirripedes are
never found on any species of Balænoptera. On th e other
h and, th e Tubicinella, Coronula Ba lea ca ris and Otioiis
are often found on Uie B a læ n a My stic etus or R ig h t whale
of the Southern Seas. See E s c h iic h t, 144.

Professor E sch ric h t, in th e Danish Transactions, has
pven an ac count o f the history o f this species, and many
letails of Its anatomy, including some admirable details of
u s brain. He also shows th a t there are numerous small
tee th in tlie jaw s . (See fig. a t pp . 331-335), besides the two
large teeth m front. H e regarded the Anarnac or Monodon
spurius, O. Fab. as the common Hyperoodon, in which
F ab n c iu s mistook th e lower for the upper-jaw. T h e fat of
Hyperoodon is purgative, as F abricius describes to be the
peculiarity o f the A n a r n a c ; and Professor E sch ric h t, in
h is unpublished paper, has proposed the name o f Cheno-
cet’us, inste ad o f Hyperoodon, which is founded on an erroneous
description. T h e name Goose-whale, or its translation,
is applied to this animal, in most p a rt o f th e seas
where it inhabits.
T h is genus m ust h e common in the A rctic seas. F ranklin,
in his second voyage, p. 206, observed many skulls round
one of th e winter houses of the Esquimaux, and Sir John
R ichardson informs me, th ey resemble a saddle, and that
th e blowers, o f th e animals were far back an admirable
description o f the peculiarities o f this genus.

Dr. Jacob, in his description o f Cetodiodon Hunteri,
D u b lin P h il. Jour. 1825, observes, there are no tee th in the
palate. T h ere is a skeleton in Mus. Col. Surg. Dublin ; a
skull, R oyal Dublin Society ; and a skull in th e Museum of
the School o f Anatomy, Peter’s Street, Dublin. H e further
remarks—T h e four skulls in Dublin belong to one species,
and have two teeth in lowerjaw, hid in the gums.
Fig. 4 and 5 o f the same p late, represent one o f the
skulls o fth is species in the Dublin Museum, from a drawing

There is a skeleton in the Museum of the Edinburgh

Mr. Thompson (Mag. Nat. Hist. 1838, 221), considers
H u n te r’s and Boussavd’s cetacean as identical, and Dal’s
th e male of the same species. He describes a specimen
stranded near Hu ll, in 1837; it has two strong, robust
te e th a t the extremity of the lower jaw, covered and
entirely concealed by the gums. Tho skull corresponded lu
its general form with th e figures iu Bell’s work ; but tlic
rise”o f the back p a rt of the head is larger m proportion to
the anterior rise than in lliat figure. T h e skull measures
from the snout to the base o f the front rise 9 in ch e s; from
thence across the rise to th e base o f the second rise 1 foot ;
from thence across the hinder rise to the neck, 1 ft. 11
inches. T h e length of th e skeleton was 17 ft. 6 in. ; vertebræ,
39 ; viz., 2 cervical, 9 dorsal, with ribs ; 20 lumbar
and s ’cauclal. The skeleton of this specimen is in the

Professor Esch ric h t observes th a t it is most important in
determining o f M. Fabricius Synonyma, to a tten d lo the
Greenlanders’ names, as they are most accurate cetologists;
he observes (on th e authority o f Capt. Holbroll), “ that
two o f the animals wliich Fabricius reierred lo Physeter,
viz., the ‘Pevnak,’ which he called P. Catodon, is probably,
and the ‘Ardluck,’ P. inicrops, (which Cuvier has thought
might b e D. globiceps) is certainly, the Northern swordfish,
D e lphinus Orca." Kong. Danshe. A fh a n d l. xi. 136.
I may remark, that as far as I can make out the Danish,
it appears th a t tbe \AdiCk fi%\\ qv Balama microcephala of
Sibbald, which I thought might be A rdluk, has entirely
escaped the notice of Professor Eschricht. I must own,
that Fabricius’s description will do for Orca gladiatori
ex c ep t th a t lie calls it black, and docs n o t mention the
very remarkable white marks of th a t species, and he only
described the low e rjaw as toothed. Now the teeth of
Orca are not deciduous.
