One preserved mussel specimen including the right valve only. The specimen exhibits an oval shape; thin shell; double looped beak sculpturing; white internal coloring; tan external coloring; no external sculpturing. Collected in the Red River basin. The specimen measures between 60 - 100 mm in length and was assessed to be very-long dead when collected.

One preserved mussel specimen including both the left and right valves. The specimen exhibits an oval shape; thin shell; double looped beak sculpturing; white internal coloring; off-white external coloring; no external sculpturing. Collected in the Red River basin. The specimen measures between 0 - 60 mm in length and was assessed to be very-long dead when collected.

One preserved mussel specimen including the right valve only. The specimen exhibits an oval shape; thin shell; double looped beak sculpturing; white internal coloring; tan external coloring; no external sculpturing. Collected in the Red River basin. The specimen measures between 0 - 60 mm in length and was assessed to be long dead when collected.

One preserved mussel specimen including both the left and right valves. The specimen exhibits an elliptical shape; thick shell; single looped beak sculpturing; bluish-white internal coloring; tan external coloring; no external sculpturing. Collected in the Red River basin. The specimen measures between 0 - 60 mm in length and was assessed to be relatively-recently dead when collected.

Simultaneous size fractionation of plankton populations associated with NaH^14CO_3 and ^3H-glucose uptake was employed in eutrophic Lake Texoma (Texas and Oklahoma) and oligotrophic Flathead Lake (Montana). Autoradiography was utilized to determine the role of specific microorganisms in community metabolism. Ultraplankton (0.45-10 μm) dominated plankton numbers and metabolic activity in both aquatic systems. Many of the most abundant species were not the most productive, in terms of inorganic C fixation. Rates of heterotrophic uptake of ^3H-glucose were small in comparison to photolithotrophic uptake in both lakes, Photoheterotrophy was more extensive in Flathead Lake, Autoradiographs indicated that bacteria were responsible for observed photoheterotrophy. Oscillatoria sp. exhibited. mixotrophy in Lake Texoma,
