Original Description
Test small to medium; pores large relative to size of test, widely separated and evenly distributed over test surface; coiling relatively compact; chambers subglobular to subspherical; increasing gradually in size as added and arranged in a low trochospire of about two and one half volutions; usually six chambers in the last whorl; final chamber offset toward umbilicus; sutures distinct, deep radial and straight; umbilicus small; primary aperture interiomarginal, umbilical to extraumbilical, portici small, sounded, spatulate, rarely preserved."

Etymology: from intermedius-a-um (Latin) =intermediate or moderate.

Extra details from original publication
Remarks: H. intermedia, n. sp., is characterized by features that are intermediate between those of H. im­plicata and H. punctata. All three species have the same unique pore pattern. The chambers of H. intermedia are not as spherical as those of H. punctata and are not as ovate, lobe-shaped, and overlapping as those of H. implicata. The test is generally circular in outline.
Range: Upper Albian, Favusella washitensis Assem­ blage Zone, Hedbergella implicata Subzone and lower part of H. punctata Subzone.
Occurrence: This species is common in the Kiamichi and Duck Creek Formations and rare in the Fort Worth Formation of North Central Texas.
