Rh several observers looks as though it might have had a similar origin, notwithstanding that this hypothesis was rejected by them. (2) A flight of sea-fowl on one occasion recorded by Professor Aldis produced the appearance of a snake swimming at the surface of the water. (3) A large mass of seaweed has on more than one occasion been cautiously approached and even harpooned under the impression that it was such a monster. (4) A pair of basking sharks (Selache maxima) furnish an explanation of some of the recorded observations, as was first pointed out by Frank Buckland. These fish have a habit of swimming in pairs, one following the other with the dorsal fin and the upper lobe of the tail just appearing above the water, and, as each animal is fully 30 ft. long, the effect of a body of 60 or more ft. long moving through the water is readily produced. To this category belongs the famous serpent cast up on Stronsay, one of the Orkneys, of which an account was read to the Wernerian Society of Edinburgh; some of its vertebrae were preserved in the Royal College of Surgeons of London, and identified as those of Selache maxima by both Home and Owen. There is also evidence to show that specimens of Carcharodon must have existed more than 100 ft. long. (5) Ribbon-fish (Regalecus), from their snake-like form and great length (sometimes as much as 20 ft.), have been suggested as the origin of so-called "sea serpents," amongst others by Dr Andrew Wilson ; but Dr Günther from what is known regarding the habits of these fish, does not regard the theory as tenable. (6) A gigantic squid (Architeuthis) was most likely the foundation of the old Norse accounts, and also of those which in the early part of the 19th century came so frequently from the United States as to gain for the animal the sobriquet of "American sea-serpent." These stories were so circumstantial, so consistent, and vouched for by persons of such eminence, that no doubt was possible (notwithstanding the cavilling of Mitchell) as to the existence of a strange marine monster of very definite character in those regions. The description commonly given of it has been summed up by Gosse somewhat thus:—(i.) general form that of a serpent; (ii.) length averaging 60 ft.; (iii.) head flattened, eye generally not mentioned, some distinctly stating that it was not seen; (iv.) neck 12 to 16 in. in diameter; (v.) appendages on the head, neck or back (accounts here variable); (vi.) colour dark, lighter below; (vii.) swims at the surface, head thrown forward and slightly elevated; (viii.) progression steady and uniform, body straight but capable of being bent; (ix.) water spouting from

it; (X.) in shape like a "nun buoy." The annexed figure (fig. 1) represents one which was seen from H.M.S. "Daedalus." To show the reasonableness of this hypothesis, it may be added that gigantic Cephalopods are not infrequent on the shores of Newfoundland, and are occasionally met with on the coasts of Scandinavia, Denmark and the British Isles, and their extreme size seems to be above 60 ft., and, furthermore, that their mode of progression is by means of a jet of water forcibly expelled from the siphon, which would impart that equable motion to which several observers allude as being evidently not produced by any serpentine bending of the body. A very

interesting account of a monster almost certainly originating in one of these squids is that of Hans Egede, the well known missionary to Greenland; the drawing by Bing, given in his work, is reproduced here (fig. 2), with a sketch of a squid in the act of rearing itself out from the water (fig. 3), an action which they have been observed in aquaria habitually to perform. Numerous other accounts seem to be explicable by this hypothesis, among them may be mentioned that of a huge "snake" seen by certain of the crew of the "Pauline" in the South Atlantic Ocean, which was said to be coiled twice round a large sperm whale, and then towered up many feet into the air and finally dragged the whale to the bottom. It is now well-known that the sperm whale kills and devours Architeuthis and other large oceanic Cephalopods, and no one who has read Bullen's vivid

description, in The Cruise of the Cachalot, of the struggle between a cachalot and a giant squid, can doubt that it was a combat of this kind which was thus erroneously described. The immensely long arms of Architeuthis would not unnaturally be mistaken for a snake by sailors, and instead of being dragged to the bottom the whale doubtless sounded of its own accord as whales usually do (see ). (7) A sea-lion, or "Anson's seal" (Morunga elephantina), was suggested by Owen as a possible explanation of the serpent seen from H.M.S. "Daedalus"; but as this was afterwards rejected by Captain M'Quahae, who stated that it could not have been any animal of the seal kind, it seems better to refer the appearance to a squid. (8) A plesiosaurus, or some other of the huge marine reptiles usually believed to be extinct, might certainly have produced the
