The Parahyba, a term of doubtful meaning, has a total length of about 600 miles, a drainage area of 26,000 square miles, a navigable course of 50 miles, and a mean discharge of 53,500 cubic feet per second. On the narrow seaward slopes of the coast range there is no room for the development of any large streams. The Macacu, which enters the north-west side of Rio Bay, although one of the largest, has a course of less than 60 miles. But if the seaboard lacks copious rivers, it abounds in stagnant lagoons and land-locked inlets. South of the Lower Parahj^ba the Lagoa Feia, an old marine gulf now separated from the sea by a strip of sands, has an average superficial area of 170 square miles, and communicates through shallow creeks with numerous other lagoons clotted over the low-lying coastLnds. Northwards it is connected, during.
