T h is species was first described by me from a skull i
Brooks’now a t Leyden, and Mr. Schlegel
h a s described it from a skeleton sent from the Faroe Ts-
Brooks’ museum, which is ii
lauds. I t differs from the other species of the genus in the
nose o f the skull being more slender and the teeth more
numerous. The tee th series, as in L . E le c tra and L . Asia,
do n o t reach to the notch which separate, the beak o f the
skull from the brain-cavity.
Professor E sch ric h t informs me this species is very like
7). leucopleiirus.

Cuvier ju stly observes the beak of Lesson’s ( Voy. Coq. t.
9) figures is too pointed. Lesson also represents the
black as only occupying the upper part o f the back, as represented
jn figure 4, copied from his plate. 1 have
therefore given a new figure o f th e species, copied from a
drawing, the natural length, kindly given to me by W.
Wilson Saunders, E sq ., o f Lloyd’s, which was made by
Dr. Stevenson, during the voyage o f the ship Glenarn,
Capt. Guy, in la t. 46° 48' S., long. 142° west, Jan. 12, 1844.

Cephalorhynchus, F. Cuv.
Forehead rounded. Nose produced, bald. Dorsal fin
falcate, in the middle o f the back. Skull with the hinder
wings of maxilla horizontal, sometimes thickened on the
edge over the orbit. Nose elongate, tapering, depressed,
broader than high, convex, roundish above, and slightly
concave in front o f th e blow'ers, nearly parallel on the
sides and rounded in front. Teeth small, conical, extending
th e greater p a rt of the length of the jaw.
Most maritime persons call these animals Bottle-noses,
Bottle-heads, Floundev-heads, Grampuses, Porpoises or
Porpusses, sometimes adding Whale lo the name. They
generally confine the name of Dolphin (most used by landsmen)
to the Scomberoid fish {Co7yph<ena), which changes
colour in dying.

M. Garnot’s description, as given by F. Cuvier, is very
short, but it appears to fit th is species. The D. ci iiiuseau
cou7-{ of the Voy. a P ole Sud is said to have 44 t®eth. It
is evidently this species as determined by the examination
of the skull a t Paris, and there is a skull named D. hivitta-
