Probable Centres of Development and Migration Routes of Primates . . 369 British Mammals CHAPTER I P REFArORT SOME explanation and apology of and for the presentation of this book to the reading public is necessary, seeing that the subject of British Mammalia has been dealt with before in a general sense by such able writers as the late William Macgillivray, the late Professor Thomas Bell, and Mr. Richard Lydekker ; while groups or species of British beasts have been described in detail by Sir William Flower, the late Dr. Dobson, Mr. Oldfield Thomas, Dr. R. F. Scharff, Mr. W. E. de Winton, Professor Boyd Dawkins, Mr. J. E. Harting, Mr. Harvie- Brown, the Rev. H. A. Macpherson, Messrs. W. Thompson (Irish Mammals), Aubyn Trevor-Battye, W. Buckley, John Guille Millais,1 Lionel Adams, G. Barrett Hamilton, F. G. Aflalo, C. J. Cornish, and Dr. A. B. Smith Woodward.2 Mr. T. McKenny Hughes in 1896 wrote an admirable treatise on the origin of the breeds of domestic cattle. Mr. F. E. Beddard 1 The finest draughtsman of British beasts and birds who has yet appeared on the scene. His monographs of the Deer and the Wild Fowl of the British Islands should have been crowned by a British Academy. His study of African Mammals in "A Breath from the Veldt" is unrivalled, and will probably remain so. 2 Who, together with the late Sir Richard Owen, Professor Boyd Dawkins, and Mr. Richard Lydekker, has done much to describe the ancient mammalian fauna of the two British Islands. 2 BRITISH MAMMALS has dealt with Mammalia generally, his work in the Cambridge Natural History Series being the latest study of the subject, and in this book a good deal of incidental information is given regarding the mammals of the British Islands. The admirable work published by Dr. J. H. Blasius in 1857 on the mam- malian fauna of Germany and Central Europe contains much information on the structure and habits of beasts which also inhabit Britain ; and the great German palaeontologist, Dr. Karl A. von Zittel, in his classical Handbook of Paleontology^ has incidentally described and illustrated a good many extinct British mammals. Students who may be attracted to the study of British mammals are also advised to read the files of such periodicals as the Zoologist (London) and the Field newspaper, both of which contain first-hand information of great value on British Zoology. To all of the above-mentioned writers and publications the author of this book is greatly indebted for information, and to these separate works he refers such of his readers as are desirous of learning something more about the beasts of their own country, and who might wish for further detailed information connected with the anatomical structure or life-habits of the British Mammalia beyond what can be given within the space of this volume. To the accumulated and carefully sifted facts recorded by this formidable array of writers the author has ventured to add his own observations and theories. Although a good deal of his time has been spent in Africa, he has nevertheless from his youth up been a student of the British Mammalia in all parts of the United Kingdom. His first interest in British beasts was no doubt prompted by their aesthetic aspect, their beauty of outline or colour ; and though he has since become entangled in the fascinations of comparative anatomy, the strongest attraction which beasts and birds still possess for him lies in the part they fill (or should fill) in British landscapes. It may be necessary to apologise to the world outside Britain for any attempt to attach importance to our existing mammalian PREFATORY 3 fauna. This has become so reduced in numbers, so scarce and little evident in many of the existing species, that we should almost appoint an annual national day of humiliation for our poverty in this respect, a poverty due to the past ravages of ourselves and our ancestors, and almost unexampled in any other part of the habitable world, except New Zealand or the Pacific Archipelagoes. This book, indeed, had it only dealt with the few well- known wild beasts still lingering in Great Britain and Ireland, would not have been worth compiling. But the author has endeavoured to deal as amply as possible with recently extinct British mammals ; and to expatiate on the interesting problems concerning the origin and migration routes of the recent mam- malian fauna which has inhabited these islands since the close of the Tertiary Epoch. As one drives through the dreary streets of Outer London, or gazes on the devastation of the Isle of Sheppey, the over-building at Bournemouth, the smug villas of Torquay, the paper mills of the Mendip Hills, the factory chimneys of Yorkshire, the desolated bogs of Ireland, and the hideous prosperity of Lanarkshire and Lancashire, it is possible to derive some consolation by recalling in imagination the African elephants and the hairy mammoths, the gigantic wild cattle and clumsy horses, the sabre-toothed " tigers," the lions larger than those now existing, the enormous cave bears, spotted hyasnas, gigantic Irish deer, beavers, wild boars, and wolves which severally or together made those regions a scene of fascination and wonder even to Palaeolithic and Neolithic man. Like the writers and statesmen of modern Greece and Spain, the author's thoughts as a student of Mammalia are mentally fixed upon the glorious past, and his survey of the present is a whimpering apology. He who would fain have described how the sabre-toothed " tiger " severed the spinal column of the megaceros deer with its trenchant tusks ; how man, naked and unashamed, and armed with weapons which were poor as compared with those of the Congo Pygmy, matched himself against the mammoth and caught the aurochs in a pitfall : he, instead, must twitter on the ferocity of the weasel 4 BRITISH MAMMALS and relate park anecdotes of park-fed beasts. There are lessons, however (one must humbly admit), to be learnt even from the nineteen varieties of the wood mouse and the violent amours of the mole. But as it is the aesthetic aspect of the Mammalia which first attracted the author of this book, it is that on which he most wishes to insist in his arguments. If in any way he has brought home to his readers the importance of Mammalia to the landscape aspects of Britain, the desirability of preserving and strengthening the species that remain (not because they are good for food or sport or unobstructive to the aims of the farmer or the citizen, but because they are beautiful or stimulating to intellectual interest), he will not have written in vain. Man does not live by bread alone. He requires to fill his life with an enjoyment of beauty, a bracing of the nerves by wholesome danger, a stimula- tion of the intellect by the mysteries of Creation. If we succeed in extirpating our wild beasts and birds, or in reducing a few of them to fattened, pied, frilled monstrosities (an action which will probably proceed concurrently with the extermination of our native flora by field clubs, costermongers, and agriculturists), life in England, Scotland, or Ireland will no longer be worth living, since man cannot live by bread alone, nor can roast beef and potatoes wholly atone for the extirpation of the aurochs and the Osmunda fern. One may admire the pheasant greatly as a beautiful bird, and blind oneself to all peevish evidence brought forward to show that it is not indigenous ; but one should admit that the weasel is quite as beautiful and half again as interesting. Still more, the polecat ; while the wild cat should be permitted to make moderate ravages on live-stock, and the damage done be paid by an interested countryside from out of the rates. It was distressing to read how, during a yachting cruise in the summer of 1902, the suite that accompanied very dis- tinguished persons gleefully took advantage of their proximity to little-frequented Scotch islands and islets to shoot and leave, kill uselessly without excuse, quite a large number of the few seals which still remain in Scottish waters. The otter is being PREFATORY 5 rapidly extinguished in Wales, Devonshire, and Sussex, by unreflecting, red-faced, well-meaning, church-going, rate-paying persons on the plea that it eats salmon or trout.1 Now, what nonsense this is ! No trout that was ever served on a dish is as good as a fried sole. Salmon is a handsome-looking fish, so far as fish go, and its flesh, though very provocative of biliousness, is liked by a large number of people. But salmon is produced in such enormous abundance in North America and Norway, and is so very unlikely (owing to its habit of resorting to the sea) to become exterminated in British waters by the otter, that it would be a shame if this remarkable aquatic weasel, so beautiful an object as an adjunct to a stream landscape, were extirpated, destroyed, or even rendered wild, to gratify the angler's craze — a craze nearly as modern as golf and cricket, but not so picturesque or beneficial to athletic development. It is necessary to insist, for the future happiness of the world, on the aesthetic value of beasts, birds, and reptiles. Amphibians and fish are less worthy of regard, partly from the fact that as they live almost entirely in the water they play no part in the beauty of landscapes. As regards all invertebrates, one may disregard, destroy, or disprotect all except those crustaceans that are good for food. Butterflies and some beetles are charming in coloration and outline, but the grandest of butterflies is feeble in aesthetic value compared to a bird, and the grubs of both butterflies and beetles do unmeasured harm. Fresh-water fish should not be protected against the ravages of the higher vertebrates : they must take their chance. As regards sea-fish, many forms are either beautiful in coloration, imposing in bulk, or fantastic in shape, and therefore provocative of interest. But as it is a most exceptional incident in our lives to put on a diver's dress and 1 Here is an extract from a recent number of the Daily Graphic : " The Crowhurst Otter Hounds. — The new pack of hounds which have just been started in East Sussex to hunt the country in the neighbourhood of Hastings is to be called the Crowhurst Otter Hounds. They propose to begin opera- tions on the i8th of this month." 6 BRITISH MAMMALS descend below the level of the water, we derive but little aesthetic enjoyment from fish, and though they are estimable as a food supply, their natural domain is so vast that the only mammal who can ever bring any species of them near extinction is man himself. The present writer has little sympathy with those well- meaning but misdirected persons who, loving the Mammalia, and feeling starved in their affections as British residents, introduce into their parks and domains kangaroos, African antelopes, ostriches, or Indian humped cattle. What they ought to do (what some great landowners have done) is to reinforce and protect dwindling British species, and reintroduce those lost forms which were co-existent with man in prehistoric times, and which may still be found lingering in holes and corners of Europe, Asia, and North America. One does not wish to be unreasonable ; and few would propose the letting loose of lions in the hope of re-developing a Fells spellack in colour, and gray or grayish-yellow in the other members WHALES AND POKPOISES 45 of the family. They are ranged transversely across the palate, exactly like the furrows in the epithelium.1 In the right whales these plates are so long that, however widely the mouth is opened, they still close up the intervals between the jaws. The right whales open their mouths when they find themselves in the middle of shoals of minute crustaceans and pteropods,2 and then close the mouth, forcing out the water through the sieve of the whalebone. The tiny organisms that are prevented from escaping by the fringe of the baleen plates then fall on to the broad tongue which lies in the great hollow of the under jaw, Clione .... 11 i i 11 The little Pteropod and in this manner are swallowed through the Mollusc (bright very narrow gullet.

When the mouth is shut the long fringes of whalebone fold backwards, the front plates lying below the hinder ones, so that in a sense the long ends of the whalebone are partially contained within the approach to the gullet. When the animal opens its mouth wide the whalebone springs forward till it is perpendicular. All the whalebone whales are considered to be characterised by possessing only four true fingers in the flipper, as against the five that are generally found in the toothed whales. There is a seeming exception to this in the right whales, where the hand appears to be five-fingered ; but it is the opinion of Mr. Beddard that the presumed first finger of the right whale is really the prepollex, the additional finger which occasionally appears in mammals before the first or thumb, and which no doubt in this whale has been retained or developed for the support of the 1 These furrows exist even in the human palate. 2 The principal source of the right whale's food is a pteropod mollusc about an inch long, named Clione limacina, bright purple when alive. Specimens of this little creature are exhibited in the admirably organised Whale Gallery at the British Museum (Natural History). 46 BRITISH MAMMALS flipper. The finger which has disappeared drops out seemingly in the middle of the series, and is possibly the normal third finger. Whalebone whales, though such extreme types of cetacean development in many directions, yet retain a few primitive characteristics. The vestiges of hind limbs are more developed in right whales than in any other member of the order, for these small bones not only represent the pelvis and ischium, but also the thigh bone and a portion of the tibia or upper leg bone. All the whalebone whales, also, have double openings to the nostrils. They|further have traces of a smelling organ, which is absent from other whales. It has been already stated that all the whalebone whales, when in the fcetal stage, have teeth in the upper and lower jaws, which in calcifying are absorbed by the time the animal is born. The whalebone does not commence to form till the young whale is several weeks old. The southern right whale is now very nearly extinct. At one time it was certainly an inhabitant of the British Channel and of the North Sea, perhaps also of the Irish Sea and Atlantic coast of Ireland. It abounded in the Bay of Biscay, and was also found in the Mediterranean, and perhaps also on the east coast of North America, the South Atlantic, and the Indian Ocean. The last recorded certain appearance of the southern right whale in British waters was at Peterhead (east coast of Scotland) in 1806, though there is some evidence to show that a specimen was stranded at Yarmouth in 1846. Another was seen off Peterhead in 1872, while the bony remains of a right whale were dredged up off Lyme Regis in 1853. FAMILY : BAL^NOPTERID/E. THE RORQUALS These whalebone whales are not so much specialised as the right whales. The head is proportionately smaller, and the whalebone is much shorter. Megaptera boo-ps. THE HUMP-BACKED WHALE In this whale the flippers are very long and narrow (with only four fingers). The vertebrae of the neck are free, and not 48 BRITISH MAMMALS fused. The eye is proportionately rather large, and is situated well above the angle of the jaw. There is absolutely no trace of a neck, and the body is even more fish-like in shape than that of any other whale. There is a back fin. A row of bony tubercles, referred to in connection with other whales, often grows along the edge of the lips. The skin under the lower jaw, and along the throat and a portion of the belly, is streaked with folds, which are so marked a characteristic of the Rorquals and of the Ziphioid whales.1 There is a slight hump in the middle of the back. The head is often studded with large scaly tubercles about the size of an orange, which may also be the remains of the original bony plates that covered the bodies of the primeval whales. In colour the hump-backed whale is black above, with entirely white or black-speckled flippers, and with under parts marbled in black and white. The hump-backed whale is of almost universal distribution. As regards its connection with the British Islands, it is commonly seen during the summer off" the east coast of Scotland and the north-east and north-west of England, occasionally appearing in large numbers off the north of Ireland. This whale frequently produces two young at a birth. The hump-backed whale eats much larger molluscs and crustaceans than the right whales, and it will also swallow small fish. Baltenoptera musculus. THE COMMON RORQUAL This genus in the species next to be mentioned probably includes the largest of living whales. The Common Rorqual may be taken as a type of the genus. Curiously enough, in the rorquals, as also in the hump-backed whales, the female is generally bigger than the male. The length of the common 1 These plica, or longitudinal folds, are thought by some whalers and zoologists to serve almost the purpose of gill openings in fishes, and to oxygenate the blood from the oxygen of the water by dermal respiration. The Balaenopterids are certainly able to remain for very lengthened periods — twelve hours, it is said — beneath the surface of the water without coming up to breathe atmospheric air. WHALES AND PORPOISES 49 rorqual is not known to exceed 70 ft. The head is proportion- ately smaller to the body than in the right whales or in most of the other rorquals. It has also some slight indication of a neck. It is the species which I have chosen to illustrate in a coloured drawing, which is partly based on the painting of a rorqual cast up on the east coast of Ireland in 1860. From this painting it will be seen that in colour this whale is blackish-gray above and white beneath, though the white is often modified by gray and yellow tinges. The whalebone is yellowish gray, sometimes whitish in parts, or touched with brown or slate-gray. The interior of the numerous folds on the under surface of the body is black.1 There is a low back fin placed very far down the body not far from the tail. The common rorqual is less restricted in its choice of food than the other whalebone whales. It can swallow herrings and even larger fish as well as molluscs and crustaceans. This whale is no rarity in British waters. It is widely distributed over both the Atlantic Ocean and the Mediterranean. It is more frequently met with in the English and Irish Channels than in the North Sea, but specimens are cast up frequently year after year on the coasts of Ireland, Wales, and England. In Scotland it is met with in the vicinity of the Orkney and Shetland Islands, and occasionally in the Firth of Forth. It produces such inferior baleen and blubber as to be scarcely worth killing for commercial purposes. This, perhaps, is the reason why it still exists in considerable numbers. Bal
