The posterior slope is distinctly lighter than the remainder of the shell. Beaks are centrally placed, curved inward, and elevated well above the hinge line.

Monograph of the genus Medionidus (Bivalvia: Unionidae) mostly from the Apalachicolan Region, southeastern United States. The subfamily Ambleminae is a diverse group of fresh-water bivalve mollusks found throughout North America east of the continental divide. They are also highly imperiled due to habitat specificity, limited ranges, and complex life history (Strayer et al. 2004).Many species require free-flowing medium to large rivers, a habitat type that is extensively impacted human activity.

Many of the lake basins are simple sinks that have always been tributary to the groundwater sup-ply, while others at one time or another have formed part of the surface drainage and are therefore connected with the river systems.

In particular, the distribution of beak sculpture morphotypes across the unionoid phylogeny and, consequently, evolution of this character remain poorly understood. Based on an examination of 187 taxa, covering five of the six extant unionoid families, this study presents a new model of character evolution of umbonal sculptures in the order.
