A vast number of different genera have been founded on detached bones, bits of whalebone, and more or less complete skeletons of Right Whales coming from different parts of the world. In Dr. Gray's catalogues we find the following allowed, viz. Balaena, Eubalaena, Hunterius, Caperea, Macleayius. The number of "species" distributed among the genera is some thirteen or more, with whose names we shall not trouble the reader. As a matter of fact there are not more than two species which can with certainty be identified and distinguished, both of which are so close that they cannot possibly be placed but in the same genus, Balaena. In no group of Whales—in no group of animals probably—has imagination run riot to so terrible an extent in the formation of genera and species as in these Right Whales. This multiplication or rather division of genera has arisen from an old idea that Whales coming from different seas must be of different kinds, a notion now thoroughly exploded.
The term "Right Whale" simply means that the Whales of this genus are the right kind of Whale for the whaler to pursue. Their whalebone is longer and more valuable, while the oil is not only more abundant but of a superior quality. The two species demand a separate account.
The Greenland Whale, Balaena mysticetus, is one of the rare instances of a Whale which has an exceedingly limited range in
space. It is absolutely confined to the Arctic Ocean, and reported occurrences on our coasts are due to a confusion with B. australis, to be presently described. At the "Devil's Dyke," near Brighton, there is, or was, the skull of a most flagrant Rorqual, which is carefully labelled "Greenland Whale." This Whale grows to a length of 50, 60, rarely 70 feet. It is black in colour, save for a white patch on the under side of the jaw. The head is quite one-third of the body in length. There are a few scattered hairs at the extremity of the jaws. The length of time which this Whale can endure immersion has been variously stated. The utmost limit of endurance is stated by Scammon to be one hour and twenty minutes. The pursuit of this Whale is attended by dangers, not in the least because the animal is itself fierce and ready to attack, but simply on account of the velocity with which, and the great depth to which, it will dive, and also to the huge muscular force which is exerted in its struggles to free itself from the harpoons. It is indeed an extremely timid beast. It has been remarked that "a bird alighting upon its back sometimes sets it off in great agitation and terror." Combined with this timidity of disposition is an intense affection for its young, "which would do honour," observed Scoresby, "to the superior intelligence of human beings." Yet that trader and observer goes on to remark that "the value of the prize ... cannot be sacrificed to feelings of compassion"! The fact that this Whale and its congener, B. australis, feed among swarms of minute pelagic creatures, which they engulf in their huge mouths, led the ancients to believe and assert that they fed upon water only. When the Whale feeds it moves along with some velocity, taking in huge mouthfuls of sea water with the contained organisms, which are then strained off by the whalebone and left stranded upon the tongue.
Unlike its congener, the southern Right Whale, B. australis,[[232]] is world-wide in distribution, avoiding only the Arctic regions. Where the Greenland Whale is found B. australis does not exist. The principal differences which it shows from B. mysticetus are firstly in the relatively shorter head and shorter and coarser whalebone. In the second place it has more ribs, fifteen pairs as against thirteen; but there is apparently some little confusion in the matter of ribs. An additional rib at the end of the series
is apt to get lost, and in the skeleton of so huge and unmanageable a beast there is nothing more unwise than to insist upon, as specific characters, what may be due merely to defective preparation. This Whale has often, and the Greenland Whale also, a rough horny protuberance upon the snout known as the "bonnet." The causation of this is not clear. It has been spoken of as "a rudimentary frontal horn." But this suggestion of an Ungulate affinity can hardly be accepted. It seems to be more like a kind of corn.
This Whale was once more abundant on the coasts of Europe than it is to-day; it was much hunted by the Basques in past time. The Whale which frequented the Bay of Biscay was usually called the Biscayan Whale or B. biscayensis; but there is probably no specific difference. Among the small towns which fringe the Bay, it is very common to find the Whale incorporated into the armorial bearings. "Over the portal of the first old house in the steep street of Guetaria," writes Sir Clements Markham,[[233]] "there is a shield of arms consisting of Whales amid waves of the sea. At Motrico the town arms consist of a Whale in the sea harpooned, and with a boat with men holding the line." Plenty of other such examples testify to the prevalence of the whaling industry on these adjoining coasts of Spain and France. It appears that though the fishery began much earlier—even in the ninth century—the first actual document relating to it dates from the year 1150. It is in the shape of privileges granted by Sancho the Wise to the city of San Sebastian. The trade was still very flourishing in the sixteenth century. Rondeletius the naturalist described Bayonne as the centre of the trade, and tells us that the flesh, especially of the tongue, was exposed for sale as food in the markets.
M. Fischer,[[234]] who, as well as Sir Clements Markham, has given an important account of the whaling industry on the Basque shores, quotes an account of the methods pursued in the sixteenth century. It was at Biarritz—or as Ambroise Pare, from whom Fischer quotes, spelt it, Biaris—that the main fisheries were undertaken. The inhabitants set upon a hill a tower from which they could see "the Balaines which pass, and perceiving them coming partly by the loud noise they make, and
partly by the water which they throw out by a conduit which they possess in the middle of the forehead." Several boats then set out in pursuit, some of which were reserved for men whose sole duty it was to pick out of the water their comrades who had overbalanced themselves in their excitement. The harpoons bore a mark by which their respective owners could recognise them, and the carcase of the animal was shared in accordance with the numbers and owners of the harpoons found sticking in the dead body of the Whale. At this period the fishery was at its height. But it continued to be an occupation along those shores until the beginning of the eighteenth century, after which it gradually declined. The fishery of Whales began to be carried farther afield than the shore, and for a long time the Basques furnished expert harpooners to whaling vessels proceeding to the Arctic seas. A curious example of the continuance of the fishery until at least 1712 is given by Sir C. Markham. In the parish records of Lequeito for that year, it is noted that a couple were married who possessed between them all the necessary outfit for a whaling cruise.
The genus Neobalaena is interesting from more than one point of view. Its size compared with its gigantic relatives is small, some 16 or 17 feet. The genus bears the same kind of proportion to Balaena that Kogia does to Physeter among the Physeteridae. It is one of those Whales which are very restricted in habitat; up to the present it is only known from the Antarctic region in the neighbourhood of New Zealand and South Australia. Structurally it is in a few points intermediate between the Right Whales and the Rorquals. The head is proportionately (as well as, of course, actually) not so large as in Balaena. There is a falcate dorsal fin; but the head in outline is not Rorqual-like in spite of its similar proportions. The whalebone is long. The throat is not grooved. Neobalaena has forty-three vertebrae, of which the cervicals are all fused. There are as many as seventeen or eighteen dorsal vertebrae, the largest number in any Cetacean as far as is known. With these are articulated not eighteen but only seventeen ribs. The first dorsal vertebra appears to be without a rib. The ribs are very broad and flat. The body thus gets an appearance of a Sirenian. The lumbar vertebrae are fewer than in any other Cetacean, being only two. The scapula is more like that of the Rorquals than that of the Right Whales;
