<p><span>We describe two larger benthic foraminiferal taxa collected from wells drilled in the subsurface Eocene rocks of southeastern Florida that are new to peninsular Florida and the Caribbean region. </span><i>Saudia floridana</i><span> n.sp. is characteristic of a foraminiferal assemblage, along with </span><i>Helicostegina gyralis</i><span>, wide forms of the </span><i>Cushmania americana</i><span> group, and </span><i>Gunteria floridana</i><span>, in an upper part of the Oldsmar Formation. </span><i>Globogypsinoides browardensis</i><span> n.gen. n.sp. occurs in a second foraminiferal assemblage, along with </span><i>Borelis<span> </span></i><span>cf. </span><i>floridanus</i><span>, </span><i>Coskinolina</i><span> cf. </span><i>yucatanensis</i><span>, and as-yet undescribed large rotaliids, in a middle part of the Oldsmar Formation. The foraminiferal assemblage of the middle Oldsmar unit is ascribed an Ypresian age and the assemblage of the upper Oldsmar unit a Lutetian age. These two assemblages indicate inner shelf water depths of 40 m or less on the Florida Platform during the Early to Middle Eocene deposition of the middle to upper part of the Oldsmar Formation.</span></p>
