The distribution of species within the Gulf of Mexico is presented in Table IV, with the Gulf regions diagxammed in Figure 1. Again, some areas have been sampled often (e.g., west and northwest coasts of Florida) and other areas have received only sporadic attention (east coast of Mexico). More species occur on the limestone-based continental shelf of the eastern Gulf than on the sand and mud substrates of the western Gulf. The Gulf regions in Figure 1 correspond to the geophysical features described by Antoine (1972) as Gulf provinces. The dominant sediment types are shown in Figure 2 and reef patches are indicated in Figure 3. Most Gulf species are probably West Indian in origin or affinity (see discussion below), where the shallow water habitats are similar to Gulf regions 1, 2, and 6. The north coast of Cuba (region 7) also contains a relatively high species abundance, probably associated with the greater degxee of habitat diversity and wide depth range in that part of the Gulf. A detailed analysis of species distribution patterns, by families, will not be attempted in the present contribution.

Igure 1) 3 4 5 these regions. An analysis of breeding tiraies and collection sites of ovigerous females, combined with data on circulation patterns of currents, larval maturation periods, and tolerances to environmental parameters (temperature, salinity, oxygen content, etc.), will be necessary to establish a comprehensive biogeography of Gulf crabs. DISCUSSION The distribution of decapod crustaceans in the western Atlantic has been the subject of several discussions in recent years. Hedgpeth (1953) summarized much of what was knowia about the geology and zoogeography of the Gulf of Mexico. He emphasized the role of Pleistocene sea level changes and their effects on continuous distributions of marine organisms in the Carolinian Province, a region encompassing shores and adjacent waters from Texas to Cape Hatteras. After the Florida peninsula emerged, isolation of the Gulf and Atlantic populations occurred for many species not able to circumvent the tropical waters of South Florida. The distributions of Ovalipes and Uca were cited by Abele (1970) as examples. For this reason the range citations in the present contribution attempt to distinguish eastern, southern, and western Florida records. 3 0 0 0 2 2 5 3 0 20 4 1 0 13 26 1 8 2 10 8 2 8 118 0 0 1 0 2 1 3 1 0 7 0 1 0 6 4 1 2 1 1 6 3 7 47 0 0 0 0 2 1 3 1 0 1 0 1 0 6 0 0 0 0 0 1 3 3 22 6 2 0 0 0 0 1 4 1 0 15 3 0 0 11 7 0 8 3 2 3 3 6 69 7 2 2 3 1 4 11 5 3 0 31 4 0 0 16 35 1 8 4 6 11 3 7 161
