lyrelated to the physical features of central and eastern Cuba. The southernpart extends nearly east and west, and its major tectonic axis is in line withthe major axis of Jamaica. These two parts can be subdivided into severaltopographically distinct areas, which will be described separately. A thirdpart, which is structurally distinct from the others, is the broad coastalplain—the plains of Seibo and Bani—in the southeastern part of the island. The topographic divisions in the part of the island that is included in theDominican Republic are the Cordillera Septentrional, Samana Peninsula,Cibao Valley, Cordillera Central, Valley of San Juan, Azua Plain, Sierra deNeiba, Sierra de Martin Garcia, Enriquillo Basin, Sierra de Bahoruco,southern peninsula, and the coastal plain. The boundaries between thesetopographic areas are shown approximately on Plate I. »Vaughan, T. W., U. S. Nat. Mus.

The Cordillera Septentrional (Northern mountain system), sometimescalled the Monte Cristi Range, starts as low, rounded rocky hills nearMonte Cristi, extends southeastward for about 200 kilometers parallel tothe northern coast, and terminates near the shore of Bahia Escocesa. It ismade up of several more or less parallel ranges and a few isolated mountainmasses. The highest mountains in the Cordillera Septentrional are in its west-central part, north of Santiago, where some of the peaks are said to attainaltitudes of 1,000 to 1,400 meters above sea level. The range near San-tiago as seen from the south presents a fairly even sky line, broken by fewserrated peaks such as characterize the Cordillera Central. (See PI. II, A.)The parts of the range that project above the generally even profile haveflat or rounded tops. The south front of this range is a
