Affinities.—The females of the Florida Bay assemblage are con- siderably larger than those from the Bahamas but have very similar shape, marginal denticulation, and opaque pattern. "Bairdia" vidrix Brady, 1869, is more produced at anterior and posterior ends. Paranesidea arostrata (Kornicker) Figure 21 Bairdia arostrata Kornicker,

"Bairdia" vidrix Brady, 1869, is more produced at anterior and posterior ends. Paranesidea arostrata (Kornicker) Figure 21 Bairdia arostrata Kornicker, 1961, p. 65, pi. 1: fig. 8a-b; 8a-h. Material.—Paratype male specimen 122C-1 from Bahamas. Distribution.—Bahamas. Affinities.—No other species has been described with a copula- tory organ having a bifurcate and otherwise structureless terminal lobe. However, its median lobe and sigmoid copulatory tube are typical of Paranesidea, as are the other appendage characters and the carapace. Paranesidea algicola, new species Figures 22-24; Plate 1: figures 7, 8 Etymology.—Latin alga, seaweed + cola, dweller. Type specimens.—Holotype male USNM 121299; allotype female USNM 121300; paratypes USNM Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States National Museum; Smithsonian Institution; United States.
