The Jăn Shé, or Southern Snake. (Mai-Teu-Shé = closed up (concealed) head snake.)
Shi Chan says: “This snake is a reptile (having a wriggling motion). Its body is immense, and its motion is wrig-wriggling (jăn-jăn)[319] and slow; hence its name, Jăn-Shé. Another author says its scales have hair like moustaches (jăn). It lives in Kwangtung and Kwangsi (literally, South of the Hills). Those that do not lift their head are the true kind; in this way they were called the ‘Concealed Head Snake.’”
Sung quotes T’ao Hung King to the effect that its habitat is in Tsin-ngan (Fukien), and also Su Kung, who says that it is found in Kwéicheu and Kwangcheu, towards the south, at Kaocheu and Hoün. At several places in the south of the Hills they are still found. Hung King says the large ones (in their coils?) are several fathoms in circumference. Those that walk without raising their heads are the genuine ones. Those that conceal their heads are not genuine. Its fat and gall can be mixed together. The large ones are more than a foot in diameter and more than twelve feet long. It is a snake, but it is short and bulky. Su Kung remarks that its form resembles a mullet’s and its head a crocodile’s. Its tail is round and without scales. It is very tenacious of life. The natives cut up its flesh into slices, and esteem it as a great delicacy. Another says: When steeped in vinegar the slices curl round the chop-sticks, and cannot be released; but when the chop-sticks are made of grass stems (mong’tso), then it is practicable.
Another says: “This snake is a hundred and forty-four feet long; it often swallows a deer. When the deer is completely digested, then it coils round a tree, when the bones of the deer in the stomach protrude through the interstices of the scales.... If a woman’s dress is thrown towards it, it will coil round and will not stir.”
Shi Chan, quoting “The Wonderful Records,” says: “The boa is sixty to seventy feet long, and four to five feet in circumference; the smaller ones from thirty-six to forty-eight feet long. Their bodies are striped like a piece of embroidery. In spring and summer it frequents the recesses of forests, waiting for the deer, to devour them. When the deer is digested the boa becomes fat. Someone says that it will eat a deer every year.”
Another author says: “The boa, when it devours a deer or wild boar, begins with the hind legs. The poisonous breath of the boa comes in contact with the horns; these fall off. The galls, the smaller they are the better they are.” Another says: “Boas abound in Wang Cheu (Kwangsi). The large ones are more than a hundred and forty feet long. They devour deer, reducing the horns and bones to a pulp. The natives use the dolishos and rattans to fill up the entrance to its den. The snake, when it smells them, becomes torpid. They then dig him out. Its flesh is a great delicacy. Its skin may be made into a drum, and for ornamenting swords, and for making musical instruments.”
The Yu Hăng Chi says: “Rustic soldiers in Kwangsi, when capturing boas, stick flowers in their heads, which when the snake observes, it cannot move. They then come up to it and cut off its head. They then wait till it exhausts itself by its jumping about and dies. They then take it home and feast on it.” Compare Ælian [De Naturâ Animalium, lib. vi. chap., xxi.]: “They hung before the mouth of the Dragon’s den a piece of stuff flowered with gold, which attracted the eyes of the beast, till by the sound of soft music they lulled him to sleep, and then cut off his head.”
The Shan Hai King says: “The Pa snake can eat an elephant, the bones of which, after three years, are got rid of. Gentlemen that eat of this snake will be proof against consumption.” Kwoh P’oh, in his commentary, says the boa of to-day is identical with the Pa snake.
