The mussel, kupang (mytilus), rimis (donax), kapang (Teredo navalis), sea-egg, bulu babi (echinus), bia papeda (nautilus), ruma gorita (argonauta), bia unam (murex), bia balang (cuprea), and many others may be added to the list. The beauty of the madrepores and corallines, of which the finest specimens are found in the recesses of the Bay of Tappanuli, is not to be surpassed in any country. Of these a superb collection is in the possession of Mr. John Griffiths, who has given, in Volume 96 of the Philosophical Transactions, the Description of a rare species of Worm-Shells, discovered at an island lying off the North-west coast of Sumatra. In the same volume is also a Paper by Mr. Everard Home, containing Observations on the Shell of the Sea Worm found on the Coast of Sumatra, proving it to belong to a species of Teredo; with an Account of the Anatomy of the Teredo navalis. The former he proposes to call the Teredo gigantea. The sea-grass, or ladang laut, concerning which Sir James Lancaster tells some wonderful stories, partakes of the nature of a sea-worm and of a coralline; in its original state it is soft and shrinks into the sand from the touch; but when dry it is quite hard, straight, and brittle. FISH. The duyong is a very large sea-animal or fish, of the order of mammalia, with two large pectoral fins serving the purposes of feet. By the early Dutch voyagers it was, without any obvious analogy, called the sea-cow; and from the circumstance of the head being covered with a kind of shaggy hair, and the mammae of the female being placed immediately under the pectus, it has given rise to the stories of mermaids in the tropical seas. The tusks are applied to the same uses as ivory, especially for the handles of krises, and being whiter are more prized. It has much general resemblance to the manatee or lamantin of the West Indies, and has been confounded with it; but the distinction between them has been ascertained by M. Cuvier, Annales du Museum d'Histoire Naturelle 22 cahier page 308.* (*Footnote. "Some time ago (says Captain Forrest) a large fish, with valuable teeth, being cast ashore in the Illana districts, there arose a dispute who should have the teeth, but the Magindanoers carried it."

The grampus whale (species of delphinus) is well known to the natives by the names of pawus and gajah mina; but I do not recollect to have heard any instance of their being thrown upon the coast.
