Howellella (Howellella) latisinuata Kozłowski, 1929 Fig. 20A View Fig .
1929 Spirifer View in CoL (? Crispella View in CoL ) latisinuaus sp. n.; Kozłowski 1929: 197, pl. 11: 1–7.
1985 Howellella latisinuata ( Kozłowski, 1929) ; Nikiforova et al. 1985: 48, pl. 13: 1–3.
Material.—Four complete shells and 37 fragments of shells and single valves embedded in rock. The specimens were recovered from several beds in the interval extending from 0.2 m below the S–D boundary (bed −10) up to 12.3 m above the boundary (bed 115).
Remarks.—Fragmentary material from Dnistrove conforms with this species, which was described from the basal part of the Borshchiv Horizon ( Kozłowski 1929: 197–198, pl. 11: 1–7; Nikiforova et al. 1985: 48, pl. 13: 1–3), in having a small shell and very few, weak radial plications. The largest complete shell in the present material (see Fig. 20A View Fig ) measures 8.2 mm in length and 10.7 mm in width. Nikiforova et al. (1985) designated the neotype of the species from the Khudykivtsi Beds exposed at Olkhovtsy village (about 8 km
NW from Dnistrove). Stratigraphic and geographic range.— Nikiforova et al.
(1985: 48) confirmed that the species is confined to the Khudykivtsi Beds (former Tajna Beds).
