I amused them with some drawings; among others they recognized that of the Pearly Nautilus, but said it was rarely procured at this place, but was occasionally seen off the coast. They named it “sea shrimp,” Udang laut; (Udang, shrimp; and laut, sea;) they were not acquainted with the Orang Utan, of which I showed them an engraving, but immediately knew that of the _Hylobates syndactyla_, or “Ungka” ape, which, they observed, was found in the woods of the interior of this island, but was very difficult to capture alive. The rajah having remained for some time on board, retired with his attendants to the boat, and returned on shore, under a salute of three guns from the ship, which compliment he also received on coming on board. The rajah of Pedir is related to the king of Acheen, and the territory is tributary to the Acheenese ruler. The population of the Pedir district, (which does not extend far along the coast, but to some distance inland,) is stated to be 100,000, and has several petty rajahs tributary to it; but they appear all petty rajahs along this coast, paying homage and tribute to the Acheenese king. Often during the cool evenings, I amused myself by wandering about the extensive beach on this coast, to observe and collect such marine productions as might be interesting; a great number of dead shells strewed the beach, but living shells, or those containing the soft parts, were rare. Observing an antenna of some crustaceous animal projecting from the moist sand, left by the receding of the tide, I pulled it, and drew out two fine king crabs, jointed together by their under surfaces, and thus united burrow in the sand; they are called “Ecan, mimi” by the Javanese, and, on this coast, they are named “Moi, moi.” The male is larger than the female; they are eaten by the Javanese, but on this coast they are not eaten, although the natives observe the Chinese are fond of them.[144] The females lay their eggs in the sand, after carrying them for some time, and, in about the second month, the young are produced; these animals are perfectly harmless; they crawl rapidly, and when touched draw the upper part of the shell a little inwards; and, as they move, the long antenna bears a resemblance to a tail. When placed on the back, they find much difficulty in regaining their natural position.
