The Hantu Kubor (Grave Demons) are the spirits of the dead, who are believed to prey upon the living whenever they get an opportunity. With them may be classed the "Hantu orang mati di-bunoh," or "spirits of murdered men." "The Hantu Ribut is the storm-fiend that howls in the blast and revels in the whirlwind." [207] The Hantu Ayer and Hantu Laut are Water and Sea-spirits, and the Hantu Bandan is the Spirit of the Waterfall, which "may often be seen lying prone on the water, with head like an inverted copper (kawah)," where the water rushes down the fall between the rocks. The Hantu Longgak [208] is continually looking up in the air. Those who are attacked by him foam at the mouth. The Hantu Rimba (Deep-forest Demon), Hantu Raya [209] ("Great" Demon), Hantu Denei (Demon of Wild-beast-tracks), the Hantu-hantuan (Echo-spirits), and I think the Hantu Bakal, are all spirits of the jungle, but are perhaps somewhat less localised than the large class of spirits (such as the Malacca-cane, gharu, gutta, and camphor-tree spirits) which are specially associated with particular trees. The Hantu B'rok is the Baboon Demon (the B'rok being what is generally called the "cocoa-nut monkey," a sort of big baboon); it is sometimes supposed to take possession of dancers, and enable them, whilst unconscious, to perform wonderful climbing feats. The Hantu Belian, according to many Selangor Malays, is a tiger-spirit which takes the form of a bird. This bird is said to be not unlike the raquet-tailed king-crow (chenchawi), and to sit on the tiger's back; whence it plucks out the tiger's fur and swallows it, never allowing it to fall to the ground. [210] The Hantu Songkei [211] is the spirit who so often interferes with the toils for catching wild animals and snares for wildfowl (yang kachau jaring dan rachik). He is described as being invisible below the breast, with a nose of enormous length, and eye-sockets stretched sideways to such an extent that he can see all round him. The following charm is recited in order to "neutralise" his evil influence:--
