GENOA, Gulf of, anciently called Sinus Ligusticus, is a large bay in the Mediterranean, lying N. of the island of Corsica, and washing the southern shores of the Sardinian provinces in Italy. No precise points can be named as marking its limits, for it opens widely and imperceptibly from the main body of the Mediterranean. It may, however, be said to comprise the whole space north of the parallel of 43. 40. N., though it is more usual to confine the appellation to that portion of this large bight which lies to the north of the parallel of San Remo, 43. 48. 41. N. Lat., and 7. 50. 0. E. Long. Thus defined, its entrance is about 140 miles in width, and its extreme breadth 54 miles. Its outline embraces the beautiful minor bays of Spezzia and Rapallo, as well as the capes of La Mele, Chiapa, and Venere.
