PREFACE.
THis descriptive Catalogue of the Marine Mammals in the
Anatomical Museum of the University has been compiled
with the view of enabling a public, wider than that which
can visit the Museum, to have the means of knowing the
extent of the collection, and the opportunities which it affords
for the study of the anatomy of these mammals. In the
number and variety of species it ranks after the British
Museum and the Museum of the Royal College of Surgeons
of England, and is, I believe, third in the United Kingdom
in the number of specimens of Cetacea and Pinnipedia
which it contains; whilst, in species of Cetacea frequenting
Scottish waters, it is larger and more complete than either
of those important collections.
The Museum has acquired its examples of Cetacea mainly
from the proximity of Edinburgh to the Firth of Forth and
the North Sea, and the not infrequent opportunities occurring
for the examination and preservation of specimens of whales
stranded on the adjoining coast. Since the end of the seven-
teenth century, when Sir Robert Sibbald and Sir Andrew
Balfour formed in Edinburgh their joint Museum, naturalists
living in that city have availed themselves of these oppor-
tunities, and in the eighteenth and nineteenth centuries the
capture of many specimens was recorded. Early in the
nineteenth century Professor Robert Jameson, Dr John
Barclay, and Dr Robert Knox preserved in their Museums
the skulls and skeletons of various species which they had
Vv
al PREFACE.
examined. Since that time the Professors of Anatomy in the
University, and other naturalists trained in the Edinburgh
School, of whom I may especially name Sir John Struthers,
have published descriptions and have made collections which
have contributed to the growth of the Anatomical Museum.
The Museum is also much indebted to the late Professor
Sir Wyville Thomson and to Sir John Murray for a collection
of skulls and skeletons of Cetacea and Pinnipedia brought
home by H.M.S. Challenger, which have been described in
the Zoological Reports of the Expedition. More recently
Dr Wm. 8. Bruce has generously presented skeletons of the
Pinnipedia which he had collected during the voyage of the
Scotia in the Antarctic Ocean, examples of which had not
previously been in the Museum. Students and young medical
graduates of the University who have from time to time
taken part in whaling voyages to the Arctic Ocean, more
especially Dr Robert Gray, have also contributed specimens
of Cetacea and Pinnipedia from that region.
Preliminary to writing the description of the osteological
section I consulted Professor Robinson, the Conservator of
the Museum, and with his approval I arranged with Dr
T. B. Johnston, one of the Demonstrators of Anatomy on
his staff, to draw up a card list, in which the nature of
the specimen and the species and genus to which it belonged
were to be noted. I desire to express my indebtedness to
Dr Johnston for the assiduity and care which he gave to the
execution of this part of the work. In the description of the
bones I have availed myself, so far as seemed necessary, of
the details recorded in my published papers, and it may be
stated that the account of the skeleton of Balenoptera sibbaldi
has been drawn up from notes made during my dissection of
this animal more than forty years ago, and not previously
published.
As regards the specimens illustrative of the soft parts,
which with few exceptions are preserved wet, the descriptions
PREFACE. vil
of the preparations made by Professor John Goodsir have
been taken from a manuscript catalogue written under his
supervision. In drawing up the description of those added
by myself I have, as with the bones, made use of my printed
papers and of notes not previously published.
In selecting from the extensive literature of the subject
generic and specific names for the Cetacea, Sir Wm. H.
Flower’s Catalogue of the specimens in the British Museum,
1885, has been taken as the guide. His classification of all
the Baleen Whales in a single family Balznide has not,
however, been adopted, as the structural characters which
collectively distinguish the Right Whales from the Rorquals
are so numerous and important as to justify a division into
the two families Baleenidee and Baleenopteride.
In the classification of the Pinnipedia the generic and
specitic divisions adopted in my Challenger Report, 1887, on
these mammals have been followed in the Catalogue.
The description of the specimens in each part, for each
family, genus, and species respectively, has been preceded
by a brief statement of the distinguishing characters, so
that the Catalogue can be used by the student as a hand-
book or guide in discriminating the families, genera, and
species to which they belong.
The illustrations are in some cases from the blocks em-
ployed in my published memoirs referred to in the text, but
the majority have been specially prepared for the Catalogue,
either from photographs or from original drawings of the
objects. I wish particularly to thank Mr Ernest J. Henderson,
the Assistant Conservator, for many photographs, especially
those of the skeletons suspended in the Museum reproduced
in Plates I., V., VI., and for the help which he has given in
making the measurements detailed in the Catalogue. To Mr
James T. Murray I am indebted for many careful drawings,
more especially of the series of tympanic bones, which will
be of service in the study of their modifications in form in the
Vill PREFACE.
several species, and in determining their value as furnishing
specific characters. The drawings have been reproduced as
process blocks by David Stevenson & Co. I wish also to
express my thanks to the authorities of the Public Museum,
Dundee, of the Museum of Zoology, Cambridge, of the
Museum of the Royal College of Surgeons, England, for
permitting me to obtain drawings of three tympanic bones,
examples of which are not in the Anatomical Museum; also
to the authorities of the Royal Scottish Museum, Edinburgh,
and of the Smith Institute, Stirling, for permission to examine
specimens in their collections.
I refer also with pleasure to the grant of money, by the
Executive Committee of the Carnegie Trust, towards the
cataloguing of the Museum, which has made it possible to
produce this illustrated volume.

WHALES AND DOLPHINS.
INTRODUCTION.
Scornanp, from its position between the North Sea and the Atlantic,
and through the great firths or estuaries which penetrate inland for
many miles, is favourably situated for the study of the Ceracka. The
Orkney and Shetland groups of islands to the north, and the Hebridean
islands to the west of the mainland, with their bays and intervening
straits and channels, add largely to the coast-line. The Cetacea, in
their migrations at some seasons to the north, at others to the south,
not infrequently become stranded, and their capture gives opportunities
to Naturalists to determine the Species and to become acquainted with
their Anatomy.
Ample evidence exists that, in Prehistoric times, before the land
and the sea had assumed their present level, whales, sometimes of
great dimensions, had been stranded both on the east and west
coasts.
As portions of the skeletons of some of these animals are in the
Anatomical Museum, it may be of interest to relate the conditions
under which bones of the prehistoric whales have been found.
From time to time specimens have been exposed in the banks of
the Irvine river, Ayrshire, not far from the town of Irvine. The
Rey. D. Landsborough stated that in 1790 some bones were found
in the bank of the river where a new channel had been formed. In
1863 a further discovery of a portion of the skeleton of a whale was
made in the river bank about a mile from the town, and the same
distance from the sea. The bed of the river at the spot was said to
be about 25 feet above sea-level. Some of the bones were removed
and presented to the Glasgow University Hunterian Museum. In
1892 another series of bones was exposed, about 250 paces from the
spot where the skeleton was found in 1863. One of large size was
a part of the skull, and it was said to have rested on a bed of shingle
stones and gravel, immediately below which was a thin layer of
peaty-looking substance from half an inch to 2 inches in thickness.
The skull bone is preserved in a museum in Kilmarnock. From its
size and character the skull was probably that of a Balenoptera. Mr
John Smith, in a description of the geological position of the Irvine
Whale Bed, stated that he saw the specimen in setu lying in a darkish
sand about 3 feet above the water of the river, and perhaps 10 feet
4 SPECIMENS OF CETACEA.
above the level of high water. The skull appeared to be in the same
bed as that in which the bones were found in 1863, and the bed
belonged to his group of forty-feet Beach Beds, in which layers of peat
occur, and numerous organic remains, including those of horses and
whales, have been found (Trans. Geol. Soc. Glasgow, vol. x., 1896).
In 1823 Sir G. S. Mackenzie of Coul communicated to the Royal
Society of Edinburgh (Yransactions, vol. x.) an account of the
vertebra of a whale exposed in a bed of bluish clay near Dingwall,
in Ross-shire, in a raised beach about three miles from the sea
-and about 12 feet above high-water mark. No attempt apparently
was made to discriminate the species of whale to which the vertebra
belonged.
The part of Scotland which has given the most abundant evidence
of the presence of skeletons of whales in raised sea-beaches is the
valley of the Forth, more especially in the precincts of Stirling.
The recorded examples have been summarised from time to time by
the Rev. Charles Rogers in his guide-book to the Bridge of Allan, by
Mr David Milne Home in his Ancient Water-Lines in Scotland
(1882), and recently and more fully by Mr David B. Morris, in The
Raised Beaches of the Forth Valley (1892, reprinted 1901). Mr Morris
has collected not fewer than fourteen records of bones of whales
exposed in the fifty-feet raised beach bordering the river Forth and
the upper end of the Estuary. They were imbedded in the Carse blue
clay subjacent to the soil now worked in agriculture, and were met
with either in making roads or drains, or in digging the clay for the
manufacture of bricks. The clay frequently contains shells of various
species of molluscs, foraminifera, etc., now inhabiting the adjoining
sea, and the whales’ bones usually occur from 20 to 30 feet above the
present high-water level.
The earliest and most complete discovery was at Airthrey, near
Stirling, in July 1819, of the skeleton of a whale, the length of
which was roughly estimated at about 72 feet. The bones were
lying in blue silt at a depth of between 4 and 5 feet from the
surface of the ground, and 24 feet above high-water level of the
river Forth. An account of the discovery was given in the Edin-
buryh Philosophical Journal, vol. i., by Mr Robert Bald. In a
letter in my possession, written on 20th August 1819 by Mr Bald
to the Rev. Dr Baird, the Principal of the University, it is stated
that on the previous day the bones were dispatched by steamer
to be deposited in the University as most interesting specimens of
natural history. The letter contained an inventory of the bones,
as fallows: head bone, jaw bones, forty vertebre, thirteen ribs, one
shoulder-blade, swimming paws, various broken bones, an ear bone,
deer horns, one of which was stated in Mr Bald’s paper in the
Philosophical Journal to have been perforated. The bones were
placed in the Natural History Museum, then under the charge of
Professor Rt. Jameson, which was transferred in 1856 to the Science
and Art Deparment, and formed the nucleus of the Natural History
Collection in the Museum, now known as the Royal Scottish Museum.
INTRODUCTION. 5
In the catalogue of a museum formed in Stirling during the first
half of the last century by the late Mr John Macfarlane, after-
wards transferred to the Smith Institute, is an entry, “Part of a
whale’s skeleton found at Airthrey,” which leads one to think that
some of the bones had been received there, though they cannot now
be identified.
In 1823 the workmen employed in deepening a drain in Dunmore
Park exposed in the stiff clay subsoil a number of large bones of a
whale. Mr Blackadder and Mr Keddoch stated in the Hdin-
burgh New Philosophical Journal, vol. xi., 1824, that they were
about 2 feet from the surface, and from 23 to 24 feet higher than
tidal high-water mark. The bones were chiefly vertebree, and were
presented to Professor Jameson for his Museum. It would appear
from the New Statistical Account of Scotland, vol. viii., 1842, that
whales’ bones had been also found in 1817 to the north of the
mansion-house of Dunmore, upwards of a quarter of a mile from the
river bank.
In October 1824 bones of a whale were exposed in Burnbank, on
the Blair Drummond estate, seven miles west from Airthrey, and
twelve miles from Dunmore. They were imbedded at a depth of
4 feet in the Carse clay, nearly a mile from the river Forth, and
within 400 yards of the boundary where the clay ends (Mr Home
Drummond and Mr Blackadder in Mem. Wernerian Soc., v., 1826).
The bones recognised were a large portion of the cranium, comprising
the occipital, frontal, and a part of the superior maxilla, also a scapula
and several vertebre in a mutilated state. A part of a stag’s horn,
perforated like that found with the Airthrey whale, accompanied
the bones, and the objects were presented to the Museum of the
University.
Distinct records therefore exist that portions of the skeletons of
whales from three localities in the Carse of Stirling were presented
to the Natural History Museum between the years 1819 and 1824.
No catalogue of the fossilised bones seems to have been in existence
at the time when the University Collection was transferred to the
Museum of the Science and Art Department.
It is, however, fortunate that the head bone specified in the
inventory in Mr Bald’s letter preserves a label, “ Airthrey Fossil
Whale,” which identifies it as from that animal, and from it we can
form an idea of the magnitude of this whale. The specimen consisted
of the occipital bone, with its condyls and the foramen magnum,
together with the adjoining portions of the temporals. The large
supra-occipital sloped upwards and forwards. Its posterior surface
was slightly concave ; it had in the mesial line a low ridge, and it is
ridged also on each side (figure, p. 6).
At each side of the occipital a massive squamoso - zygomatic
temporal projected outwards for 2 feet 2 inches, and added materially
to the breadth in the temporo-occipital region. I have compared
the diameters with the corresponding bones of the Longniddry
B. sibbaldi and of B. musculus :—

The Airthrey and Longniddry whales corresponded closely in these
dimensions, and as the latter was nearly 79 feet long, Mr Bald’s
estimate of 72 feet scarcely perhaps gives the full length of the
Airthrey specimen. Both animals much exceeded the dimensions of
B. musculus.
The condyls of the Airthrey skull were separated in front by a
groove 2 inches wide, whilst behind they were 44 inches asunder.
The foramen magnum was almost a circle, and measured 53 by
52 inches, The vertex border of the bone was not pointed, but had
a convex curve 184 inches long.
One lumbar vertebra had been retained in the Royal Scottish Museum,
a massive bone, 3 ft. high and 3 ft. 5 in. between the tips of the trans-
verse processes ; the spine was | ft. 10 in. long, the body 15 in. by 12
in. It resembled the lumbar vertebre of the Longniddry B. sibbaldi.
Eight ribs were still preserved in the Museum. One, a second rib
with a distinct capitular process, measured 8 feet 4 inches along the
curve from the articular tubercle to the opposite end, whilst the
chord of the are was 6 feet. Another was 9 feet 55 inches along the
curve ; the chord was 7 feet 64 inches. Another, though somewhat
broken at one end, was 9 feet 7 inches along the curve; it had been
fractured near one end during life, as Mr Bald had noted, but had
become repaired, and was thickened at the place of fracture. The
shortest rib, evidently one of, if not the hindmost, was 5 feet
54 inches along the curve, and the chord was 4 feet 1 inch, From
INTRODUCTION. 7
the magnitude of the bones and from the close correspondence of
the occipital region with that of the Longniddry whale, I believe
that the Airthrey specimen should also be regarded as Balenoptera
stbbaldi.
In addition to the bones now described, but not having a label or
other mark of identification, is a right scapula which in general appear-
ance and texture resembles the bones found in the Carse clay. Its
length between the two angles was 5 feet 2 inches, and the glenoido-
vertebral diameter was 3 feet 5 inches. It was an unusually thick
plate for a scapula, 23 inches at the superior angle, 2} inches at the
inferior angle; the vertebral border, forming a continuous convex
curve, was 14 inch thick. The long diameter of the glenoid fossa was
15 inches. The coracoid process was represented by a rough tubercle
with a base of 2 inches; no acromion was present ; the dorsal
spine was only faintly indicated. The scapula (figure above) differed
materially from that of B. sibbaldi, in which, as can be seen in
Plate IV., the bone is triangular, the vertebral border is moderately
convex, the spine is distinctly marked, the acromion and coracoid are
large processes, and the blade is relatively thin. The Carse scapula
corresponds, in its general form and in the absence of processes, with
the description and figures given of this bone in Megaptera boops.
The longest Megaptera yet recorded was 514 feet (True, Whale-
bone Whales of the North Atlantic, 1904), but the customary
length is between 40 and 50 feet. In the Tay specimen described
by Sir John Struthers, the ossification of which was not completed,
the length was 40 feet.
In the absence of any history of this scapula, one can only speculate
on its origin. There is no evidence that it was found at Airthrey,
and there is reason to regard the skeleton from that locality as a
8 SPECIMENS OF CETACEA.
B. sibbaldi, a whale which far exceeds the dimensions of Megaptera.
But two other localities in the Carse also contributed bones to the
old Natural History Museum, and amongst those sent from Blair
Drummond a scapula is definitely named. Granting, as its appear-
ance indicates, that the bone had been a part of the skeleton of a
Carse whale, the interest centres on this rather than on the
particular skeleton of which it had been a part, for it proves that
in prehistoric times the Hump-backed Whale had frequented the
great estuary of the Forth, a fact which had not previously been
recognised,
Mr Milne Home stated in his work, U’he Estuary of the Forth, that
in 1859 bones of a whale were found in Christie’s brickfield, Stirling,
but no details were given. In 1863, in the same field, called
Cow Park, which lies in a loop of the river Forth, about 200 yards
from the new bridge at Stirling, a large part of a skeleton was
exposed. I was told by Provost Christie that the bones were
imbedded in the blue clay, 13 to 14 feet below the surface of the
ground, and from 3 to 4 feet above the level of high water. They
were given to the Corporation of Stirling, who some years afterwards
presented them to the Anatomical Museum of the University. They
were much broken, but I have succeeded in piecing together
fragments of the skull and of the mandible, to permit some measure-
ments to be made and to partially restore their form (Catalogue,
p- 68). Several ribs were obtained, usually broken, one of which,
with its two-headed vertebral end, is described and figured, p. 69 ;
also a number of vertebre, much injured, which belonged to the
several groups. In the Smith Institute, Stirling, is a rib 5 feet
long in the are and 45 inches in the chord, marked as found in this
brickwork, 1863; and not unlikely some other ribs, one of which is
6 feet 54 inches long in the arc, 5 feet 14 inch in the chord, though
not marked, are from the same animal. The Catalogue of this
Institution also contains an entry: ‘‘ Vertebre of skeleton of a whale
found in Christie’s brickfield, Cow Park.”
In 1864 a portion of the skeleton of a whale was exposed in a
brickfield at Cornton, situated between Stirling and the Bridge of
Allan. It was about 9 feet from the surface, in clay, in which
Mr Haswell determined the presence of shells of oyster, mussel,
cockle, and whelk, also a Trophon and a Balanus, with fragments
of bark, hazel nuts, and the fibres of marsh plants. The bones were
lying about 30 feet above the present sea-level, and the skull, in a
fragmentary state, along with the ear bones, was given to a museum
in Glasgow. ‘The tympanic was 43 inches long, 24 inches broad,
2? inches high. The periotic was fused with it, also an elongated
mastoid. Its characters were those of Baleenoptera, and it was
apparently a young B. musculus,
In April 1877, whilst a drain was being dug at Woodyet, Meikle-
wood, Gargunnock, about six miles west of Stirling, some vertebrae
of a whale were seen in the clay subsoil. The excavations were
resumed in September, and a skull, more vertebrae with the plates
INTRODUCTION. 9
not fused with the bodies, and some ribs were brought into view.
They were about 100 yards from the river Forth, which bounded one
side of the field, and they were estimated to be about 30 feet above
high-water level. I visited the place when the excavations were in
progress; the vertebrae were not in serial order, but were lying
irregularly in the clay, turned over on their sides, and the skull was
at the west of the spine. The bones were removed to the lawn at
the mansion-house, where I again saw them and counted two dorsal,
seven lumbar and one cervical vertebra, the pair of Ist ribs, a part
of another rib, and the hinder part of the skull. The right side of
the occipital bone was injured, but the left side and the condyls
were present; the basi-occipital was jointed but not fused with
the post-sphenoid, with which the base of the vomer was articu-
lated ; parts of the temporal bones were present, and on one side
the periotic was im situ. I measured the largest, most perfect
lumbar vertebra, 26 inches from the ventral surface to the tip of
the spine and 30 inches between the transverse processes; the body
was 10} inches in dorsi-ventral and 124 inches in transverse
diameter. The left Ist rib was almost entire, but the right one was
broken. The body of a cervical, that of a lumbar, and the tympanic
bones are described on p. 69 of the Catalogue of the Anatomical
Museum.
The bones were retained for a time at Meiklewood, and were sub-
sequently presented by Mrs Dalrymple to the Smith Institute. The
collection consists of the occipito-temporal region of the skull; the Ist
dorsal vertebra, 234 inches between tips of transverse processes, with
the body 74 inches transversely and 53 inches dorsi-ventrally ; a 1st
left rib 56 inches long on the arc and 234 inches in the chord, some
broken vertebra, and plates and portions of ribs. An atlas vertebra,
the anterior articular surface of which measures 14 by 7? inches, may
also belong to this animal.
The implement of deer’s horn lying beside the skull was obviously
similar to those found along with the skeleton of the Airthrey
Whale and with that subsequently exposed at Blair Drummond. It
was at one time customary to call them harpoons or lances, but
their shape, without a point, and the position of a hole for a handle
in the middle and not at one end of the implement, unfit them
for the purpose of a harpoon or lance. The chisel-shaped end,
again, adapts them for dividing the blubber, and it is probable
that the neolithic people descended from the adjoining heights
and used them to remove the blubber from the carcase of the
stranded whale (figure, p. 70).
In the Smith Institute is a scapula, which unfortunately bears
no mark of locality, though there can be no doubt, from its appear-
ance, that it was from the Carse clay. Possibly it may have been in
the Macfarlane Collection already referred to. Its diameters were :
between anterior and posterior angles, 344 inches ; glenoido-vertebral,
331 inches. The vertebral border was convex and thick ; both the
coracoid and acromion processes were absent. The scapula therefore

had the characters of a Megaptera, and it provides another example,
though smaller in size, to that already described on page 7.
Notices of the Carse whales above described are included in Mr
Morris’s narrative, but in addition he refers to the remains of one
found at Woodlane, Blair Drummond ; to another at West Carse, on
the Touch estate ; to a third in a brickfield near Falkirk, about three
miles from the sea; to two whales found at Dunmore in 1846 and
1857 ; also to a vertebra in the neighbourhood of Grangemouth, in a
bed of clay 9 feet from the surface and 12 feet above high-water
mark, in which Mr John Burns recognised shells of Cardium,
Littorina, Ostrea, Buccinum, also a few of Tellina proxima and
Trophon scalariforme.
In the reprint of The Raised Beaches of the Forth Valley, 1901,.
Mr Morris related the discovery in 1897 of portions of ribs of a
whale whilst digging a drain from the village of Causewayhead,
Stirling, to the river Forth. They were lying in the clay close to
where it joined the old coast-line of the fifty-feet raised beach. Mr
Morris asked me to examine the remains, and I observed that the end
of one rib was cleft into the cancellated tissue, and its sides were
formed by the outer and inner surfaces of the bone. The condition
was not natural, and seemed as if it had been artificially shaped
by the hand of man. A short distance from the ribs a part of the
beam, with one of the tines, of the antler of a red deer was found,
The surface of the beam and tine was not roughened, but smooth
as if from use; and as the tine was pointed, it had the appearance
of having been employed as an implement for boring.
In the process of excavating in 1903 for a new dock at Grange-
mouth, near the point where the river Carron debouches on the
estuary of the Forth, numerous bones were found about 30 feet below
the present surface, in the same horizon. Mr Donald D. Arbuthnott,
the engineer in charge, wrote: ‘“‘The superjacent material consisted
of 5 to 6 feet of sand, a considerable thickness of mud (watery clay),
then a bed of gravel, on which the bones were lying, 2 to 3 feet thick,
composed of roundish boulders, some of considerable size, bedded in
clay. The gravel bed covered a large area and dipped to the Forth.”
Specimens were preserved, and were presented through Mr Morris
to the Smith Institute. I have had the opportunity of examining
them. The specimen which is of most interest in the present
INTRODUCTION. ILil
inquiry is the left mandible of a whale with sockets for large teeth.
From a comparison of the mandible with the jaws of the Odontoceti
in the Anatomical Museum, it is from an Orca gladiator, Though
injured at the tip of the symphysis and at the condylar end, its
length was 32 inches, and the empty sockets for eleven teeth were
at the symphysial end. As the outer wall of the sockets was broken
away, their cavities were exposed. The largest socket was 34 inches
deep, and 1} inch in antero-posterior diameter. The symphysis was
rough, 73 inches long and 2% inches broad. The mandible behind
the last socket was 11 inches in vertical diameter (figure, p. 10).
This is the first locality from which fossilised remains of the Killer
Whale (Orca) have been recognised in Scotland.
Professor Cossar Ewart has carefully examined the other mammalian
remains from the same spot and has named them—two skulls of
broad-browed ponies of the forest type; skull of a ram of the peat
or turf type (Ovis palustris); skull of a dog in size resembling a
greyhound ; and an imperfect antler like that of a reindeer,
The first naturalist to write a detailed account of the large whales
which frequent the Scottish seas in modern times was Sir Robert
Sibbald, one of the founders of the Royal College of Physicians,
Edinburgh, and author of works on local history, geography, and
natural objects. He published in 1692, with illustrations, a volume
entitled Phalainologia Nova sive Observationes de Balenis in Scotiz
littus nuper ejectis, In it he gave an excellent account of a Rorqual,
78 feet long, a male, stranded in September 1692, near the castle of
Abercorn, on the Firth of Forth. The configuration and dimensions
of the head and body and the black colour of the baleen plates and
bristles were so precisely described that one readily recognises it as
a typical specimen of the great whale which is now appropriately
named Sibbald’s Whale, Balxnoptera sibbaldt.
Another Rorqual, a male, 46 feet long, was stranded in November
1690 to the west of Burntisland. Its length was proportioned to
its girth, and its form was more slender than the Abercorn specimen.
The head was slightly oblong, and the snout was midway between
the acute and the obtuse. The baleen plates were not described.
Its length exceeded B. rostrata and B. borealis, The upright dorsal
fin and the short pectoral limb proved that it was not Megaptera ;
its more slender form and the shape of the beak showed it not to
be B. sibbaldi, so that it was probably an immature B. musculus. A
character was given by Sibbald which he regarded as peculiar,
that the nares were not situated on the head, but in the beak 6 feet
8 inches from the extremity of the superior maxilla.
Sibbald recorded the stranding of a male Sperm Whale about 52
feet long, in February 1689, at Limekilns, on the Firth of Forth.
Also a female on one of the Orkney Islands in 1687, the head’ of
which was 8 or 9 feet high. Its length was not given. From the
form of the head, the position of the blowhole, the arrangement of
the teeth, and the spermaceti obtained from the head, this animal was
12 SPECIMENS OF CETACEA.
obviously also a Sperm Whale. In a manuscript addition to the copy
of the Phalainologia Nova in the Library of the Royal College of
Physicians, Edinburgh, are two figures of a Sperm Whale taken at
Monifieth, February 23, 1703; they are believed to have been
prepared for a new edition of the Phalainologia which was not
published. Sibbald also gave an account of small whales, with teeth
in both jaws, captured in 1690 and 1691 at Culross, Blackness, and
Kirkcaldy. Some were 20 to 25 feet long, and he styled them Orce.
He also speaks of twenty-five small whales, which ranged from 10
to 12 feet in length, being cast ashore in 1690 on Cramond Island.
Some may possibly have been of the genus which we now call Orca,
others Globicephalus. Sibbald published in 1697, with the title
Auctarium Musei Balfouriant e Musxo Sibbaldiano, a catalogue of
the specimens collected by Sir Andrew Balfour and himself. Fifteen
of these were derived from the Whalebone Whales, the Sperm Whale,
and the Orcas described in the Phalainologia Nova; they probably
constituted the first cetological collection made in Scotland,
During the eighteenth century and the early years of the nineteenth
the stranding and capture of occasional isolated specimens were
recorded. Mr James Paterson, the keeper of the Balfourian Museum,
stated that in 1701 a male Sperm Whale nearly 52 feet long ‘‘came
in at Crawmond.” In 1769 Mr James Robertson described a male
Sperm Whale, 54 feet long, also stranded on Cramond Island. In
1756 another was said to have come ashore on the west coast of
Ross-shire.
Professor John Walker examined a Rorqual cast ashore at Burnt-
island in June 1761, the sex of which was not determined. It was
46 feet long; the pectoral limb was 5 feet long and 9 inches in
greatest breadth ; the tail was 114 feet in transverse diameter; the
distance from the dorsal fin to the insertion of the tail was 10 feet
10 inches ; the height of the falciform dorsal fin was 2 feet 10 inches,
whilst at the root it measured 2 feet 7 inches; the longest baleen
plates were 2 feet, their breadth was 6 inches, and they were said
to be “nigra splendentes” (Proc. Soc. for Investigating Natural
History, Edinburgh, 1782, No. 13, p. 91). From the colour of the
baleen, it was probably an immature B. sibbaldi.
Two White Whales were recorded as cast ashore in 1793, east
of Thurso. One was killed in 1815 on the Forth near Stirling,
and was described by Dr Barclay and Mr Patrick Neill. More
recently, in 1845, one was stranded at Auskerry, one of the Orkneys.
The discovery of the skull in 1800 near Brodie House, Moray Firth,
by Mr Sowerby, gave us the first specimen of Mesoplodon bidens, or
Sowerby’s Whale. The Rev. Dr Fleming described in 1808 a
Narwhal obtained at the Sound of Weesdale in Shetland; but
Tulpius had recorded, so far back as 1648, the capture of a specimen
near the Isle of May, at the entrance to the Forth. Dr Traill
established in 1809 the frequent occurrence of the Pilot Whale,
Globicephalus melas, in the Orkneys. In a volume of Essays on
natural history, published in 1808, Professor Walker included

Dr John Fleming, in his History of British Animals, brought the
classification and characters of the Mammalia up to the knowledge
of that day.
A great step in advance was made when Dr Robert Knox and
Mr Frederick J. Knox undertook the dissection of a Great Whale
stranded at North Berwick in October 1831. The whale, a male,
was 78 feet long, and was named by them the Balena maximus
borealis or Great Northern Rorqual with integumentary folds.
It was fortunate that it came into the possession of so able a
practical and scientific anatomist as Robert Knox, by whom the
skeleton and many preparations in illustration of the anatomy of
the soft parts were preserved, and a description of the animal was
published. Specimens in illustration of the anatomy of other
whales he also obtained: for example, the Piked Whale or
Balenoptera acuto-rostrata, the Greenland or Right Whale, a Dolphin
named Delphinus tursio, the Common Porpoise, and the Gangetic
Dolphin. To these were added the skeleton and soft parts of the
Dugong. The collection was arranged and exhibited as a Museum in
Edinburgh, and a descriptive catalogue of the specimens was published
by Mr Frederick J. Knox in 1838. It was unfortunate that, after
being on view for some years, the collection had to be dispersed ; but
Professor John Goodsir, who was then actively engaged in developing
the Anatomical Museum of the University, acquired a number of the
specimens which are recorded in the present Catalogue. The skeleton
of the Great Rorqual became the property of the City of Edinburgh,
and after being exhibited for a number of years in a building in the
now extinct Zoological Gardens, has found a permanent resting-place
in the Royal Scottish Museum. Professor Goodsir added to the
Anatomical Museum, from his own dissections, the skeleton and
many soft parts of a Hyperoodon stranded in 1845 at Alloa (Catalogue,
p. 81). He also prepared a number of dissections, many of which
illustrated the growth of the baleen plates, from a Rorqual, about
35 feet long, probably B. musculus; and he procured from whaling
captains the skull of a well-grown B. mysticetus, also the skeleton
of a younger animal, which, as well as the skeleton of Hyperoodon,
was not articulated until the collection was arranged by me in 1885
in the present Anatomical Museum of the University.
My studies of the Cetacea began in 1867 with the dissection
of the Pilot Whale, Globicephalus melas, one of a school which
visited the Firth of Forth in that year. My imterest was in-
tensified when in 1869 a Great Rorqual, Balenoptera sibbaldi, was
stranded at Longniddry ; the study of its anatomy occupied many
months of my time, and enabled me to identify it as the same
species as Knox’s North Berwick Whale and Sibbald’s Great
Rorqual stranded near Abercorn in 1692. Since then I have enjoyed
the opportunity of examining Bpt. musculus, borealis, and rostrata,

I have consequently been enabled, as will be seen in the Catalogue,
to add a large number of specimens to the Museum, and I am
indebted to many pupils and kind friends for help in procuring them.
I may especially refer to the late Mr John Anderson of Hillswick,
Shetland, and to his three sons, two of whom were my students and
are now graduates of the University. In my studies on the Cetacea
I have derived great assistance from the memoirs and systematic
writings of Cuvier, Eschricht, Reinhardt, Sir Richard Owen, J. E.
Gray, Van Beneden, Gervais, James Murie, Sir Wm, Flower, and
more recently F. W. True.
Concurrently with my work on the Cetacea in Edinburgh, the
late Sir John Struthers was conducting, during his occupancy of the
anatomical chair in Aberdeen, important investigations into their
anatomy. He published a series of detailed descriptions on the limbs
and other parts of the Greenland Right Whale, on Balxnoptera
musculus, on a White Whale (Beluga) killed at Wick in 1884,! on
Monodon, Globicephalus, and a valuable monograph on Megaptera
boops. The University Museum is deeply indebted to him for a
number of specimens which illustrate their anatomy, reference to
which is made in the Catalogue.
The establishment, during the last few years, of whaling stations in
Shetland, and at Harris in the Long Island, has led to the capture in
Scottish and adjoining waters, in addition to Bpt. sibbaldi and musculus,
of large whales which had previously been regarded as only occasional
visitors. I would refer especially to a number of Sperm Whales,
to Balenoptera borealis, and even to Balena biscayensis, a species
which for many years past was thought to be extinct, though now
the trend of opinion is to regard it as the northern form of Balena
australis.
The Anatomical Museum contains examples of 22 genera and of
33 species of Cetacea, and of the species 21 were stranded on the coast,
or otherwise captured in Scottish waters. Including the soft parts,
the Collection consists of about five hundred specimens.
From the dimensions of the principal building of the Museum, it has
been possible to suspend a number of articulated skeletons, even of the
largest species. In the construction of the roof provision was made
for the insertion of strong steel bars, from which skeletons have been
suspended, As ‘is customary in collections, many of the species are
represented only by their skulls, on the differences in which naturalists
are in the habit of relying in the study of specific and generic
distinctions. In preparing the Catalogue I have paid special
attention to the characters displayed by the following regions as
1 Sir Wm. Flower recorded (Proc. Zool. Soc., 1879) the capture of a Beluga near
Dunrobin, Sutherland ; and Professor Alex. Meek the capture, in June 1908, of a
male, 14 feet 2 inches long, at the mouth of the river Tyne (Zvans. Nat. Hist.
Soc. Northumberland, New Series, vol. 1.).

useful in classification: the fronto-naso-premaxillary ; the macxillo-
premaxillary rostrum, or beak; the hard palate and the pterygoids ;
the teeth, their absence, or presence, size, form, and numbers; and
the tympano-periotic bones.
The Fronto-naso-premaxillary Region.—In the Baleen Whales this
region is symmetrical. In the genus Balena the nasals occupy the
interval between the upper ends of the right and left premaxille, and
are flattened and horizontal on the dorsal surface. In Balenoptera
musculus the inner border is raised into a crest, the dorsum is grooved,
and slopes gently downwards and forwards ; in b. s¢bbaldz the nasals
are large, dorsum convex slopes rapidly downwards and forwards,
outer border is raised into a crest ; in B. borealis the nasals are short,
with a low mesial ridge, dorsum faintly concave from side to side,
convex from behind forwards, sloping down in front; in B. rostrata
the nasals are small, convex on dorsum, have no crest mesially or
laterally, and dip rapidly down in front. In Megaptera the nasals
are narrow, pointed, ridged mesially, concave laterally ; an internasal
fissure receives the nasal spine of the frontal, which appears on the
surface between the two nasal bones. The nasal ends of the pre-
maxille incline inwards and are bent with an inward convexity.
In Physeter the region shows an extreme degree of asymmetry.
The upper end of the right premaxilla spreads upwards and to the
left, and occupies the place of the right nasal; the left premaxilla does
not reach the left nasal; the anterior nares are displaced, the right
somewhat anterior to the left. The maxille and frontal are raised into
a high crest which bounds the bowl-shaped chamber for the spermaceti.
In Ziphius the conjoined nasals and the premaxille are expanded
and raised as asymmetrical eminences, which overhang like the eaves
of a house the anterior nares ; the right nasal and premaxilla are more
expanded than the left.
In Hyperoodon the nasals are concave forward, the premaxille
are expanded asymmetrically, and the anterior surface overhangs
the nares; the striking specific character is the development of
the maxillary crests, which are separated from the nasals by a
deep cleft.
In Mesoplodon the nasals are vertical and locked in between the
overhanging borders of the premaxille, which form rough ridges.
In Platanista the marked specific character is the pair of plate-like
maxillary crests which curve inwards and almost meet above the
middle of the face.
In the Delphinidz the nasals do not form a roof for the narial
opening, but are short nodular bones which lie behind the opening, and
their long axes are almost vertical. The premaxille are at the sides
of the nares and not quite symmetrical, for the left, as a rule, is
shorter than the right. In Monodon, Phocena, Grampus, Lagenorhyn-
chus, and Cephalorhynchus the nasal end of the premaxilla is generally
convex, or marked by a longitudinal ridge. In Delphinapterus,
Orcella, Orca, Globicephalus, Delphinus, Prodelphinus, and Tursiops
the nasal end of this bone is either flat or slightly concave.
16 SPECIMENS OF CETACEA.
Masxillo-premaxillary Region, Rostrum, or Beak.—In Balena the beak
is distinguished by its high antero-posterior arch and narrow palate,
from the relatively flattened dorsum and wide palate in Baleenoptera
and Megaptera. In Balena the tip of the beak is pointed and formed
by the premaxille ; the length of the beak is five times greater than
the breadth at the base: in B. musculus the side of the beak is not
quite straight, and the length is nearly twice the breadth at the base :
in B, sibbaldi the side of the beak is more convex, the superior and
the premaxillz turn inwards at the tip, and the length is about 14
more than the breadth. In B. borealis the side of the beak is
straight, the superior and premaxille extend directly forwards to the
tip; but at its base the superior maxilla curves gently outwards ;
the length of the beak is rather more than twice the breadth.
In B. rostrata the tip is pointed, the sides are straight, the interval
between the premaxille widens out to an ellipse in front of and
opposite the base, and the length is about 13 more than the breadth.
In the above measurements, as well as in those which are to
follow, I have not, as is the practice with some anatomists, compared
the length of the beak with that of the entire skull. I have pre-
ferred to take the length of the beak from the tip to the notch in
the superior maxilla which marks the line of the base, whilst the
base is measured in a straight line between the opposite maxillary
notches. By these measurements a better idea can be formed of the
range in outline of the beak, from a broad triangle such as exists
in Orea and Globicephalus, to the long, narrow, rod-like beak in
Platanista.
In Ziphius the character which at once arrests attention is the
dense medio-rostral bone which occupies and is fused with the
spout-like vomer in the interval between the two premaxille, and
the length of the beak is about 14 times more than the breadth.
In Hyperoodon the medio-rostral cartilage is little if at all ossified,
and the length is about 23 times more than the basal breadth.
In Mesoplodon the medio-rostral is ossified in the adult; the beak
is more slender than in Ziphius, and its length is about 23 times
more than the breadth at the base. In Platanista the beak is com-
pressed laterally so that the length varies in different specimens from
8 to 12 times more than its breadth at the base.
In the Delphinide the surface of the premaxille in the beak itself
is not uniform. In a number of species, as Beluga, Globicephalus,
Grampus, L. albirostris, D. delphis, Prodelphinus, and Tursiops, it is
convex, a character which extends as far as or near to the tip; in
Phoczena and Orcella the convexity is faintly marked ; in Monodon,
Cephalorhynchus, Orca, and Z. acutus the premaxilla is smooth,
flattened, or at times faintly concave ; and in Globicephalus the pre-
maxilla is so broad as largely to conceal the superior maxilla. The
proportion of the length of the beak to the breadth at the base
varies with the species. In D. delphis the length is 3 times more
than the breadth ; in Tursio, Z. acutus, Cephalorhynchus, and Beluga
the length is about twice greater; in Phocena and Orca, about 13;
INTRODUCTION. i574
in Monodon, Orcella, Grampus, L. albirostris, about 14; and in Globi-
cephalus the length is about 14 more than the breadth at the base.
The Pterygoids and Hard Palate.—In the Baleen Whales the
pterygoids are small and separated mesially by a wide cleft; the
palate plates of the palate bones are large. In Physeter, Hyperoodon,
Ziphius, and Mesoplodon the pterygoids are large and meet mesially.
In an important memoir Sir Wm. Flower pointed out (Proc. Zool.
Soc., 1883) the characters of the pterygo-palatal region in the classi-
fication of the Delphinide, and subsequently Mr F. W. True, in his
Review of the Delphinide, has gone over the same ground. It may
be sufficient, therefore, if I confine myself to a brief statement of
the characters observed in the skulls in the Anatomical Museum.
The hinder end of the hard palate is formed by the pair of
pterygoids situated immediately behind the palate plates of the
palate bones; each is hollowed into a sinus opening backwards.
They lie in the same transverse plane, but their relations to the
middle line vary with the species. Thus, in Beluga, Cephalorhynchus,
Phocena, Orcella, and in some skulls of Orca they are separated by
a wide cleft; in Globicephalus, and sometimes in Orca, the interval
is a narrow fissure; in Monodon, Grampus, L. albirostris and acutus,
Delphinus, Tursiops, they meet mesially and complete the hard
palate behind. The palatal plate of the palate bones in Globi-
cephalus, Phoceena, Delphinus sends a process backwards which
intervenes between the more anterior half of the inner borders of
the two pterygoids,
The hard palate is chiefly formed by the pair of superior maxille
which usually articulate in the middle line. Sometimes, as in
Physeter, Hyperoodon, Ziphius, Mesoplodon, Tursiops, Lagenorhyn-
chus, Prodelphinus, they do not meet mesially in their whole length,
and allow the lower edge of the vomer to appear. The premaxille
are only visible in the palate near the tip. In the Baleen Whales the
palate is perforated by large foramina for the blood-vessels and nerves
which supply the folds and papillz on the mucous membrane, from
which the baleen plates are developed and grow. In Balena the
palate has a strong keel in the middle line, which is not so marked
in Balenoptera.
Delphinus, as the genus is now limited, is distinguished from
other Delphinidze by a mesial palatal ridge and a wide, deep longi-
tudinal groove on each side of the ridge.
Teeth.—It is now recognised that in the Cetacea generally
rudiments of teeth are formed in the gums of the foetus. In the
Mystacoceti they disappear at an early stage, never cut the gum nor
possess functional value. In the Odontoceti, again, the teeth
develop and acquire functional importance. As a rule, the teeth
are small, conical in shape, and have the same form in whatever
part of the jaw they are situated, though sometimes they assume
specific characters. In Layard’s Mesoplodon, for example, a pair of
mandibular teeth grow to form broad, strap-like fangs of great size
which enclose the beak of the upper jaw. In Sowerby’s Whale a
9
_
18 SPECIMENS OF CETACEA.
pair of mandibular teeth are triangular in shape and laterally com-
pressed, In the Narwhal the single developed maxillary tooth
forms a spirally twisted horn, or tusk, 8 to 10 feet long. In the
Porpoise the numerous small teeth are spade-like in form, some of
which show indications of cusp-like projections.
In the descriptive part of the Catalogue the skulls of several
species are described, eg. Platanista, Phoceena, Cephalorhynchus,
Lagenorhynchus, Delphinus, Tursiops, Steno, where the teeth are
numerous in both upper and lower jaws; in others, as Orca,
Globicephalus, the teeth are greatly diminished in number, and
are situated at the anterior ends of both jaws; in Physeter
numerous functional teeth are found in the mandible; in Grampus
only three or four teeth are present on each side of the symphysis
of the mandible; in Ziphius and Hyperoodon the fully developed
teeth are reduced to a pair at the free end of the mandible, but as
they are almost buried in their sockets they can have but little
functional value.
The Tympano-Periotie Bones.—In Balena the height of the
Tympanic, though not equal to the length, is materially greater
than the breadth; the keel on the lower aspect is very prominent ;
the outer surface is divided by a long, wide, oblique groove into two
unequal convexities, of which the posterior is much the larger ; the
inner surface is convex and striated, and its upper border, where it
turns into the tympanic cavity, is nearly horizontal, and at its
anterior or Eustachian end is notched, and well above the keel.
In B. mysticetus this border is thicker than in B. australis and
biscayensis, though not so thick and rounded as in Balenoptera and
Megaptera.
In Balenoptera the height is almost the same as the breadth,
and each of these is much less than the length. The inferior
keel is not so prominent as in Balena, and the adjoining surfaces
are not so laterally compressed. The groove which separates
the outer surface into two unequal convex divisions is short and
comparatively narrow. The inner surface is convex, and where it
turns round into the cavity is striated, much thicker, and more
rounded at the upper nearly horizontal border than in Balena ;
anteriorly it is notched for the Eustachian tube. B. sibbaldi and
B. musculus can be distinguished from B. borealis and B. rostrata
by their larger dimensions. In B. musculus the inner surface is
more convex, the keel is not so sharp, and the adjoining surfaces
are not so laterally compressed as in B, sibbaldi. B. borealis has
+he outer surface less convex, the anterior border is not so well
defined by a groove, the keel is a narrow ridge, the inner surface
is more flattened than in B. musculus. In B. rostrata the height is
‘more than the breadth; the two divisions of the outer surface are
almost equal in antero-posterior diameter.
In Megaptera the height and breadth are almost equal, the two
divisions of the outer surface are prominently convex, the inner
surface is also distinctly convex; the anterior end is blunt and

continued into the keel; the posterior end shows a differentiated
ridge. Entrance to the cavity has a thick, rounded, striated border,
with somewhat depressed notch at Eustachian end. The keel is not
prominent, and blends with the roughened adjoining inner and outer
surfaces.
The Tympanic in the Odontoceti is readily distinguishable from
this bone in the Baleeu Whales; on the inner surface the lower
border of the entrance to the tympanic cavity is not horizontal or
nearly so, but slopes downwards and forwards, so that the EKustachian
end is immediately above the anterior end of the inferior surface. In
Physeter, a toothed whale of gigantic proportions, the bone is smaller
even than in B. rostrata, which has scarcely half the bulk of the
Sperm Whale. Even in an adult male Cachalot its length was only
22 inches. Its outer surface in the posterior part is raised into a
strong, curved ridge, continuous with the mallear or lip-like process
on the upper border, and prolonged downwards to the inferior surface.
The inferior surface is grooved and bilobed behind ; the outer is larger
than the inner lobe, roughened in front, above the anterior end
of which the Eustachian mouth of the cavity opens by an arch-
shaped orifice. In Kogia the tympanic is not raised on the outer
surface into a prominent ridge as in Physeter. The bone is bilobed
posteriorly, the outer being the larger; the inferior surface is smooth ;
the inner surface is bounded above by the rounded border of the
opening into the cavity, which is divided by a shallow depression
into an anterior and a posterior part; the Eustachian end of the
cavity opens by an arched border.
In the Ziphiine the tympanic varies in its characters. In
Hyperoodon it is almost as large as in the sperm whale; the upper
border of the outer surface gives rise to a curved lip-like process, but
its extension down the surface is feeble. A well-marked outer lobe
is behind, but the inner is a rudimentary tubercle; a narrow rough
ridge, forming a low keel, projects from the inferior surface, close to
the Eustachian opening at its anterior end. In Ziphius the lip-like
process is limited to the upper border of the outer surface; the
inferior surface has a low keel which ends behind in. the projection
or outer lobe, though the inner lobe is represented by only a minute
tubercle ; the Eustachian opening is close to the anterior end of the
inferior surface. In Mesoplodon, again, the tympanic is definitely
two-lobed behind—the outer, the larger, smooth and rounded; the
inner well marked, separated from the outer by a shallow cleft ; the
inferior surface, relatively broad, is not keeled but grooved, and the
Eustachian opening is close to its anterior end.
In Platanista the tympanic is 2 inches long, bilobed posteriorly,
the outer being the larger lobe ; inferior surface is grooved and is
prolonged into a pointed process, immediately above which is the
Eustachian opening of the tympanic cavity. The lip-like process
projects feebly from about the middle of the upper border.
In the Delphinide the tympanic is bilobed posteriorly, and the
outer is larger than the inner lobe. The lobes are best seen on the
20 SPECIMENS OF CETACEA.
inferior surface, where they are separated by a cleft, varying in width
and depth in different species, which is usually limited to the region
of the lobes, though sometimes, as in Tursiops and Monodon, it is
prolonged forward on the inferior surface as a median groove. The
outer lobe is smooth and rounded, the inner is usually roughened and
pointed, though in L. acutus, Tursiops, and Cephalorhynchus it is more
truncated. The outer surface has about its middle a low raised
process, which is continued into the lip-hke mallear process on the
sharp upper border of this surface, but is not prolonged to the inferior
surface.
The Periotic proper is a dense, hard bone, which is fused with the
tympanic in the adult. Its cerebral surface is pierced by one or two
large canals for the auditory nerve; its tympanic surface, next the
cavity, has two fenestra, the ovalis and rotunda, to the former of
which the stapes sometimes remains attached, though the incus may
have been lost and the malleus fused with the lip-like process of the
upper border of the outer surface of the tympanic. In the Baleen
Whales the periotic proper, which encloses the internal ear, is much
smaller than the tympanic, and is smooth and convex on its inferior
surface ; but continuous with it a mass of cancellated bone, by which
it is attached to the squamosal, is sometimes regarded as a mastoid
process.
In the Toothed Whales the periotic is not so strongly anchored to
the squamosal as in the Baleen Whales, and is more easily lost. In
many species it is not so long and broad as the tympanic, but
Hyperoodon and Orca form exceptions. A plate-like surface at the
posterior end of the periotic articulates with a corresponding surface
of the tympanic. In Hyperoodon, Mesoplodon, Ziphius, and Phocena,
they are plane surfaces, and the articulation is one of apposition.
In Physeter and many Dolphins, as Globicephalus, Orca, Grampus,
they are concave and striated, and the articulation is feebly denticu-
lated. A rounded, bullet-shaped prominence, immediately below
and on the tympanic side of the internal auditory meatus, marks the
position of the labyrinth.
For purposes of Classification the Cetacea are arranged in two sub-
orders, Mystacoceti and Odontoceti.
The Mystacoceti (M.C.) (Whalebone Whales) consist of the families
Baleenidee (Right Whales) and Baleenopteridee (Rorquals).
The Odontoceti (O.C.) (Toothed Whales) consist of the families
Physeteride (Sperm and Beaked Whales), Platanistidz (Fresh-water
Cetacea), and Delphinidez (Dolphins). :

Firth to Kirkealdy, where it was flensed. The
animal was described by Professor Sir Wm. Turner,
Proc. Roy. Soc. Edin., December 1869, and more
fully in the Transactions, vol. xxvi., 1870. The
bones of the skeleton in the Museum were presented
by the Science and Art Department.
The fetus, a male, was 19 feet 6 inches long; the
girth behind the dorsal fin was 3 feet 6 inches, the
height of that fin was 64 inches, and the length of
the pectoral limb was 3 feet 7 inches. Figure

The atlas of the female is 3 feet 2 inches in trans-
verse diameter. The anterior surface has two smooth
concave areas for the occipital condyls, separated in
part by rough bone and in part by a deep notch con-
tinuous with the neural canal, but occupied by a strong
ligament which is connected with the stunted odontoid.
The upper part of the canal for the cord is 43 inches
wide, and only 2! inches in vertical diameter. The
posterior surface has a large crescentic articular
area for the axis. The neural spine is stunted; the
lamin are strong and flattened, and pierced by a
foramen for the sub- occipital nerve. On each ae
is a strong transverse process, triangular, and with a
pointed end, but not perforated by a lateral foramen.
The axis is 3 feet 8 inches in transverse diameter.
The anterior surface has a large crescentic articular
area for the atlas, and the concavity of the crescent
is roughened for the stunted odontoid. The neural
spine is massive; the transverse process, broad and
flattened, consists of a parapophysis and a_ dia-
pophysis united at their outer ends and enclosing a
large lateral foramen. The 3rd to the 6th ver tebrie
have flattened bodies, with a moderate neural arch and
spine and a triangular neural canal. The transverse
processes are long and slender; the two divisions

7th cervical differed from the 6th in the transverse
process being formed only of the diapophysis or that
which springs from the neural arch, the parapophysis
being represented by a stunted tubercle on the side of
the body. See Plates IT., IT].
In the fetus the atlas had cartilaginous neural
arch, body, and transverse processes, though an
ossitic centre had formed in the ring between the two
anterior articular areas. The diameter was 12 inches
between the tips of the transverse processes. The
cartilaginous body of the axis contained a_ thick
osseous nodule which corresponded with the future
odontoid and with the attachments of the check
ligaments. Each half of the neural arch had its
ossific nodule. The transverse processes were cartila-
ginous, and the diameter between their tips was 143
inches. In the 3rd to the 6th cervical the centre of each
cartilaginous body contained an osseous nodule about
34 by 3, inches. ‘The neural arches were cartilaginous,
and in each half a plate-like bar of bone had formed.
The large lateral foramina associated with the trans-
verse processes were complete, and their boundaries
were formed of cartilage. Between the axis and body
of the 3rd vertebra, and between the bodies of the other
cervicals, large cavities containing synovia were found,
similar to Paaees in the interver eal dises of the adult.

one was almost exclusively cartilage; four were
mostly cartilage; sixteen had a larger proportion
of bone. They were attached to the ventral surface
of the intervertebral discs. The chevron cartilage
was enclosed in its own perichondrium, and was not
continuous with the cartilage of the spine. A centre
of ossification had formed in the cartilage plate on
each side and extended into the mesial plate to form
the ventral spine, except that in the last six the lateral
plates lay in distinct perichondrial sheaths and did
not meet mesially. The chevrons extended as far as
the fourth vertebra in front of the tip of the tail, and
the last was only 4 inch by } inch in diameter. The
Ist was smaller than the 2nd, each plate of which was
2 inches long by 14 inch wide at its attachment
to the intervertebral disc. Behind the 2nd the
chevrons for some distance increased in size, and
then diminished at the hinder end of the series.
19. Rib, last left, and vertebral end of last right rib; left 3 feet
3 inches long, slightly curved; chord of are 3 feet

20. Thoracic inlet bounded by the Sternum, a cruciform
flattened bone with a short posterior limb; transverse
diameter 264 inches, antero-posterior diameter 173
inches; articulates with Ist pair of Ribs, which also
articulate with transverse processes of Ist dorsal
48 SPECIMENS OF CETACEA.
Vertebra; the transverse diameter of the inlet. is
4 feet 9 inches, the sterno-vertebral is 3 feet 4 inches.
21. Sternum of B. sibbaldi from the fetus of the Longniddry
specimen. At this stage the sternum consists of two
cartilaginous segments, an anterior three-lobed, 5°8
inches in transverse, 34 inches in antero-posterior
diameter, and an almond-shaped segment 1:1 inch in
antero-posterior, and 0°6 inch in transverse diameter.
Each segment is enclosed by its perichondrial envelope.
Described by Turner in Journ. Anat. and Phys.,
May 1870, vol. iv. See figure below.
22. Pectoral Limb, articulated skeleton of right, with scapula.
Length of scapula between angles 5 feet 7 inches;
glenoido-vertebral breadth 3 feet 3 inches; length
of acromion 1 foot 5 inches, breadth 10 inches; length
of coracoid 9 inches. From head of humerus to tip of
third or longest digit 13 feet 1 inch, length of humerus
26 inches, of radius 3 feet 104 inches, of ulna with
olecranon 4 feet 3 inches. See Plate IV.
In the fwtus much of the scapula was cartilaginous :
a plate 6 by 44 inches surrounded the posterior
angle, and from it a narrow strip was prolonged
on the vertebral border to the anterior angle. The
acromion was tipped with a plate 24 inches long.

The cartilaginous surface of the glenoid was _pro-
longed into a pointed coracoid. The humerus was
64 inches long; its head was formed by a thick
cartilaginous epiphysis which represented also the
tuberosities. The synovial membrane lining the
capsule was reflected on to the free surface of the
cartilage. The lower end of the humerus also had an
epiphysial cartilage with no trace of ossification.
The radius with its epiphysis was 154 inches long,
the ulna 144. The ulnar upper epiphysis was con-
tinued into a cartilaginous plate 5 inches by 2 inches
which formed the olecranon. See Plate IV.
At the carpal end the cartilaginous epiphysis of the
radius was distinct, that of the ulna was fused with two
of the carpal cartilages. The cartilaginous mass of the
carpus was subdivided by furrows which lodged bands
of fibrous tissue that marked off its segments. In the
proximal row were radiale, intermedium, and ulnare ;
the radiale was large, and perhaps included a non-
differentiated distal carpale; the ulnare was only
partially differentiated by a furrow, and entered into
the large cartilage continuous with the ulnar epiphysis
and the pisiform, the latter of which formed a band
parallel with the inner border of the lower end of the
ulna. In the distal row a long cartilage was opposite
the carpal ends of metacarpals iii. and iv., and doubt-
less represented C,,,; in the absence of the pollex
there was no C,, and no carpalia were differentiated
for Mii.and Mv. The four digits were i. tov. Each

unossified. D ii. consisted of M and Ph,; Di. of M and
Ph,; Div. of Mand Ph,; Dv. of M and Ph, In each
digit the osseous phalanges were united by intervening
cartilage divided into a distal epiphysis for one bone
and a proximal epiphysis for the other. Each digit
ended in a terminal rod of cartilage in which possibly
one or more additional phalangeal ossifications might
have formed. See Plate IV. and figure, p. 49.
23. Carpal and metacarpal bones and phalanges, not articu-
lated, from the older Longniddry Finner.
24. Pelvic bones, pair from female; there was no appearance of
a rudimentary femur. Each bone consists of a short
process and of two long processes, and is 17 inches
between the tips of the long processes. Figure below.
In the fwtus the pelvis was cartilaginous, 3°9
inches between the tips of its long processes. The
crus penis and erector muscle were attached to the
posterior process. Described by Turner in Jowrn. of

Donor—Captain Bottemann.
40. Vertebre, seven Cervical and first Dorsal, with inter-
vertebral discs dried and shrunken; natural skeleton.
The plates are partially ossified to the bodies. The
length of the cervical part is 3 feet 2 inches; the
greatest transverse diameter at the axis is 4 feet
6 inches. The range of rotation of the atlas on
the axis was 17°. The odontoid is stunted, and was
imbedded in a thick, strong ligament occupying
a part of the ring of the atlas, which acted as a
check to prevent over-rotation in either direction.
A shght rocking movement of the atlas on the axis
was also permitted. The cervicals in this animal
closely resembled those in the Longniddry whale,
except the 6th cervical, in which the diapophysis
was complete, whilst the parapophysis was only 10
inches long, ended in a point, and did not complete
the boundary of the lateral foramen. The first dorsal
resembled the seventh in its parapophysis being repre-
sented by a stunted tubercle. The specimen is from
a gravid female, said to have been about 90 feet long,
but not measured, stranded in October 1869, near
Hamna Voe, Shetland. Referred to by Turner in

5. Tympano-periotic bones, right, from the young skull
from East Falkland Island, No. 1; stapes in place.
Tympanic, length 13 inch, breadth 1} inch, height
§ inch. Outer surface flattened behind, moderately
convex in front, unequally divided by an almost
vertical groove, from which to the anterior border
is 1§ inch, to posterior border { inch; lip-like process
prolonged down outer surface. Inner surface moder-
ately striated, vertical diameter 2 inch behind
diminishing towards Eustachian end. Inferior aspect
bilobed posteriorly, outer lobe smooth and rounded,
larger than the rough and laterally compressed inner ;
the lobes are separated by a groove which widens out
anteriorly to 3 inch as a shallow roughened fossa,
so that this aspect deserves the name of inferior
surface; the cavity opens by a wide mouth at its
anterior end.
Compared with the tympanic of Sowerby’s Whale,
the outer lobe is smoother and more rounded, and the
groove separating it from the inner is wider, but it
does not extend so far forwards, and the inner surface
turns more abruptly from the inferior surface.

Globiocephalus macrorhynchus, Hector, Trans. Welling. Phil.
Soc , Sept. 1869.
Described by Dr J. G. Gray as the Large-headed Pilot
Whale, G. macrorhynchus, from a specimen in the
Museum, Royal College of Surgeons, London, and
localised as inhabiting the South Seas. Sir James
Hector adopts the specific name and calls it the “Black
Fish of the South Seas.” Flower, in his Catalogwe
of Cetacea, states that the British Museum contains
a stuffed specimen with its skull, from the Cape of
Good Hope. The skull, he says, is distinguished from
(7. melas by the premaxilla in the anterior half of
the rostrum completely covering the superior maxilla.
In the following specimens, presented by Sir J. Hector
to the University Museum in 1872, the premaxilla
does not in this respect differ materially from G.
melus. It is doubtful if this species should be
continued.

[Many species have been included in the genus Pro-

of which are founded on single skulls and without
doubt will need revision. I have placed four skulls
in the Museum in this genus, and I have examined
one in Mr W. Taylor’s Collection which he regards
as belonging to it. These skulls have the character
of Prodelphinus, but differ in some features from
each other, and may be arranged in two groups; in
the one the skull is longer and wider, the beak is
somewhat broader in relation to its length, and
the premaxillaries are more convex and distinctly
broader in the beak than in the other. These
characters might be regarded as specific, but with
the paucity of material for comparison at my disposal
I am not prepared to apply to these skulls specific
names. |

SEA COWS.
INTRODUCTION.
Tue Srrenta, owing to their aquatic life and fish-like shape, were
regarded by the Cuviers and their immediate successors as belonging
to the order Cetacea, and were named Herbivorous Cetacea. Further
observations into their habits and structure have shown that they
differ materially from the Cetacea, and they have had to be removed
therefore from that order. As they also differ much from other
orders of Mammals, and cannot be classified with any one of them,
these animals have to be placed in an Order apart, and the name
Sirenia, proposed by Illiger, has been adopted by zoologists.
As regards their habits, they live in the brackish water of large
rivers, estuaries, bays, lagoons, and do not frequent the open sea.
They feed on the seaweeds and other aquatic plants which grow in
these waters. They are deliberate and inactive in their movements.
They frequent the east and west coasts of Africa, the Red Sea, the
Bay of Bengal, the Malay Archipelago, the north coast of Australia,
the West Indies, some of the great rivers of South America, and up
to the latter half of the eighteenth century one species lived in the
Behring Sea.
In their external characters, the skin is not smooth and shining
as in the Cetacea, but is rough, wrinkled and sparingly studded with
hairs; the muzzle is truncated, and on its summit the nose opens
by two orifices; the lips are provided with short, stiff bristles ; the
body is fusiform; the palpebral fissure and eye are very small; the
ear has no pinna; there is no dorsal fin; the caudal fin is horizontal,
laterally expanded, and in Halicore has a notch on the posterior
border ; the pectoral limbs are pentadactylous, enclosed in a common
envelope of skin, paddle-shaped; the pelvic bones are present, but
rudimentary ; there are no hind limbs. The head is not large in
relation to the size of the body.
In their internal structure, the brain is smaller than in the active-
moving Cetacea of corresponding size, and the cerebrum is not so
minutely convoluted. The heart is cleft at the apex. The epiglottis
is not intranarial, The stomach consists of two large compartments,
cesophageal and pyloric, and of two intermediate accessory cavities ;
a special glandular pouch opens into the cesophageal compartment.
An ileo-colic valve marks the separation of the small from the large
143

intestine ; two cecal appendages open into the commencement of the
colon in Manatus, but in Halicore the cecum is simple. The
kidneys are simple and not multilobate as in the Cetacea. The
placenta in the Dugong is arranged as a zone, and the villi are not
ditfused over the surface of the chorion as in the Cetacea. In the
shape and arrangement of the teeth and in their order of succession
the Sirenia contrast strongly with the Cetacea. The incisor and
molar teeth are separated from each other by a wide interval. The
bones are dense and heavy; the anterior nares are large and set
back. The vertebre are not fused together to form a sacrum; in
their ossification they do not form plate-like epiphyses. Chevron
bones are developed in the anterior caudal region. In Manatus there
are only six cervical vertebre. As in the Cetacea, the clavicles are
not developed. The carpus is short, but has some breadth.
Three families are recognised in the order Sirenia: Halicoride,
Manatide, Rhytinide. The Museum contains twenty-two specimens.

As the skulls were of different ages, an opportunity
to study different stages of dentition was given. In
the youngest skull, No. 4, the symphysial part of
the Mandible had four wide, shallow sockets in which
there were no teeth. In the skull No. 3, the
corresponding sockets were wider and deeper ; each of
the third pair contained a rudimentary styloid tooth
thickened at its deep end, the others were empty.
In the skull of No. 2 the sockets were moderately
wide, deep, and empty. In No. 1, the oldest skull,
the sockets were empty, four large on the right side,
but on the left a small socket was interposed between
the large second and third, making five in all. The
molar teeth in the mandible were worn and flattened
on the surface of the crown. In the youngest skull,
No. 4, were six sockets with four teeth with flattened
crowns on each side. The anterior tooth was lost; the
most posterior contained an unerupted tooth with a
148
SPECIMENS OF SIRENIA.
tuberculated crown. In No. 3 were three pairs of
molar teeth, of which the posterior, inch in sagittal
and 3 inch in transverse diameter, was the largest.
In No. 2 five pairs of sockets were present, in which
only two teeth had been preserved. In No. 1 only
three sockets were on each side; the tooth in the
middle socket measured 1} by 2 inch; the hindmost
tooth had been lost.
In the Upper Jaw the premaxillary or incisor teeth
assumed in the older skulls the form of tusks. The
youngest skull, No. 4, had two sockets in each pre-
maxilla, separated by a transverse septum, each of
which contained an unerupted tooth ; the anterior was
styliform, and the posterior about three times thicker.
In No. 3 each premaxilla had only a single large
socket for a tusk, of which the left was preserved ;
the socket was 42 inches deep, 1} inch wide. In
No. 1 the tusk was present in each premaxilla;
it projected 24 inches, and its circumference at the
mouth of the socket was 3} inches. In No. 4 the
maxillary or molar teeth had six sockets on each side ;
in the most anterior the tooth was cylindriform and
only + inch in diameter; the 2nd, 3rd, and 4th were
flattened on the crown; the 5th had recently erupted
and was tuberculated, the 6th was concealed in the
socket. In No. 3 were three pairs of sockets, and the
posterior on one side contained a worn tooth $ by
+ inch in diameter. In No. 2 were five sockets on
each side, but only three teeth with worn crowns had
been preserved. In the oldest skull, No. 1, were only
two sockets and two pairs of teeth.
From these observations it would appear that in
early life two incisor teeth arise in each premaxilla, but
that one disappears, whilst the other increases greatly
in size and forms the tusk. At the stage in which
the four incisors were seen in the youngest skull, the
more posterior in each bone was the larger, from
which it would seem as if it developed into the tusk
and caused the absorption of the anterior tooth. As
regards the molar teeth, six is the number developed
on each side, but they are not all erupted at the same
time, for when the Ist is in place the 6th is still
concealed, and before it appears the Ist and perhaps
the 2nd may be shed, so that in the course of time
four, three, or only two molars, and these the most
posterior, may be all that remain on each side. The
HALICORE. 149
succession of teeth in this animal is not therefore a
vertical succession, but in the horizontal direction, as
is the case with the true molars in man, or as is seen
on a large scale in the molar region in the elephant.
7. Sternum, Ist and 2nd pairs of Ribs, cervical Vertebrae,
Ist and 2nd dorsal. Sternum 8 inches long, divided
into two segments, the anterior 45 inches, the posterior,
34 inches, is not bifurcated at its free end; greatest
breadth about the middle 22 inches. Three pairs of
costal cartilages articulate with the sternum near its
middle, one and a half to the anterior segment, one
and a half to the posterior. Seven Cervical Vertebrez,
the anterior part of the head of the Ist rib articulates
with the side of the body of the 7th, the posterior
part with the body of the Ist dorsal. The tubercle of
the Ist rib articulates with the transverse process of
the Ist dorsal and not with that of the 7th cervical.
In the immature skeleton, No. 2, the sternum, in its
size, form, and costal articulations, closely resembles
that in No. 7, and the articulations of the vertebral
end of the Ist rib are similar. In the adult skeleton,
No. 1, the sternum is bifurcated at its posterior end
and notched anteriorly ; its mesial length is 10 inches,
whilst laterally it is 11} inches; the greatest breadth
is 33 inches. The vertebral articulations of the 1st
rib correspond with Nos. 2 and 7. The spines of the
atlas and axis, 3rd and 4th vertebre are ossified, but
in the 5th, 6th, and 7th the two halves are still
asunder. In the immature skeleton the atlas and
axis only are completely ossified.
8. Pectoral Limbs, pair of. Scapula falciform, vertebral
and anterior borders convex, anterior angle feeble,
posterior distinct, coracoid and spines present, acro-
mion short, pre-spinous larger than post-spinous fossa.
Humerus from head to outer condyl 53 inches,
upper epiphysis for head and tuberosities not fused
with shaft, lower fused, upper half of shaft broad
and deeply grooved. Radius and ulna each with
upper epiphysis fused, lower not yet united; ole-
cranon well marked, epiphysis on its tip not fused.
Radius 4% inches long, ulna 54 inches. Carpus with
proximal and distal rows; the proximal contains
radiale and ulnare but no intermedium, the distal
consists of a single bone stretching across the carpus
and articulating with five metacarpals; between the
150
SPECIMENS OF SIRENIA.
2nd and 3rd metacarpals it shows evidence on the
surface of fusion of two originally separate bones.
The pollex consists of M, and no phalanx; M,, had
two phalanges, M,,, three phalanges, M,, three pha-
langes, M,, minimus, two phalanges.
In the adult skeleton, No. 1, the scapula is 123 inches
in long diameter, 54 inches in glenoido-vertebral ; the
coracoid projects 14 inch, the acromion 1} inch from
the spine. The humerus is 7} inches long, radius 5
inches, ulna 7 inches, epiphyses all fused; the carpus
has the same number and arrangement of bones as
the above specimen; the metacarpals and phalanges
also correspond, except that the pollex has a minute
phalanx and the index has three phalanges.
The skeleton No. 2 closely resembles No. 8, but
the carpal radiale has been lost.
9. Tympano-periotic bones, right, of the Dugong, No. 4 in
Catalogue. The tympanic is an imperfect ring, the
broad end of which is directed downwards, forwards,
and inwards, and is swollen on its posterior surface.
The two cornua of the ring are fused with the periotie,
and the longest diameter is 1,4, inch; in form the
tympanic is like the cartilaginous pinna of the human
ear, but without a tubular meatus. Continuous with
the periotic is an ovoid projection which occupies a con-
cave surface in the squamous temporal. The periotic,
consisting of dense bone, is 2 inches in its longest
diameter. The chain of ossicles has been removed from
the tympanic cavity and is figured to the right of
the outer surface of the tympano-periotie.

from Otaria by the hard palate ending well in front
of the pterygoid processes, the hinder border being
usually scooped or emarginate, and the surface being

flat or nearly so. The molars are 55 Gill
regarded the Alaskan Sea Lion described by Steller
as the only species of Eumetopias, whilst others
associate with this genus the Californian Sea Lion,
the Grey Sea Lion, and Hooker’s Sea Lion. It
should be stated that, if Eumetopias is limited to

EUMETOPIAS—ARCTOCEPHALUS. Le
The presence of a large species of Eared Hair Seal on
the Auckland Islands was established by Mr J. W.
Clark (P. Z. S., 1873), who identified it with the
skulls collected by Sir J. C. Ross in his voyage to the
Antarctic, which were named Arctocephalws hookeri
by Dr Gray. The skull is distinguished by its great
length in relation to both the zygomatic and cranial
breadth. The hard palate is almost truncated, but
ends behind about opposite the middle of the zygo-
matic arch and well in front of the hamular pterygoids.
No specimen in Museum.

Facial part of skull short, forehead flattened; hard
palate moderately concave, scooped behind; zygo-
matic breadth exceeds that of cranium; mandible
with faint angle and vertically flattened sub-
condyloid process. In 1868 I described the adult
skull No. 1, and, from the cleft state of the hinder
border of the palate, named it A. schisthyperoes. It
is probably the adult female A. pusillus.
