Euvola vogdesi (concave scallop)
Taxonomy
Pecten (Pecten) vogdesi was named by Arnold (1906) [DISTRIBUTION: California-Panama (Recent); western North America (Pliocene-Pleistocene).a]. It is extant. Its type locality is San Pedro [Timms Point Silt], which is in an Irvingtonian terrestrial siltstone in the Timms Point Silt Formation of California.
It was recombined as Pecten (Janira) vogdesi by Grant and IV and Gale (1931); it was recombined as Pecten (Oppenheimopecten) vogdesi by Keen (1971), Woodring (1982); it was recombined as Oppenheimopecten vogdesi by Moore (1984); it was recombined as Euvola vogdesi by Coan et al. (2000), Hendy (2021).

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| L. G. Hertlein 1925 (Pecten (Pecten) heimi) | Shell concavo-convex, equilateral, inequivalve. Right valve highly arched, and ornamented by about 20 or 21 rounded, radiating ribs which become flattened toward ventral margin,
these separated by round-bottomed interspaces about one-half as wide as the ribs ; ribs and interspaces crossed by concentric incremental lines of growth ; ventral margin of shell rounded ; ears somewhat convex ; a distinct groove on right ear close to margin of shell, and byssal notch also present ; anterior margin of right ear somewhat convex; ear ornamented by about four or five radiating riblets and by concentric incremental lines. Left valve slightly concave and ornamented by about 17 or 18 radiating ribs which are separated by round-bottomed interspaces, the ribs and interspaces crossed by fine concentric incremental lines; a depressed area present just below the beaks; anterior and posterior margins of valve flattened, higher than the depressed inner area near beak, sloping abruptly to ears; ears concave and sculptured by fine incremental lines only. Altitude 75 mm. ; longitude 85 mm. ; diameter of right valve approximately 25 mm. ; apical angle of right valve approximately 97°. |
