Discussion.— Vogdesella sp. possesses simple carapace morphology with a postplete outline, a valve that is of uniform convexity without distinct lobes and sulci, and with wellmarked cardinal angles. It is up to 1.48 mm long and, in the material that we have examined, has a length to height ratio of 1.3 to 1.4 (25 specimens measured, NMW2004.22G.358– 378, and additional specimens in the NMW collection, samples B−D/2, B−D/3, B−D/4, and B−D/5?). The species from the Shirgesht Formation is similar to V. subovata ( Thorslund, 1948) (see Meidla 1996: pl. 16: 9), but it is shorter, more distinctly postplete, and its anterior end is narrowly rounded near the dorsal margin. Species of Vogdesella and Pariconchoprimitia Schallreuter, 1980 appear to represent end members of a range of morphological variation from flat to nodose forms (see also Jones 1986: 92; Meidla 1996: 86).
