Bathycyathus lloydi (Vaughan, 1920) Pl. 4, figs 3a–4b v*1920 Paracyathus lloydi, n. sp.: Vaughan, p. 62, pl. 10, figs 3–3b. v1920 Paracyathus thomi, n. sp.: Vaughan, p. 63, pl. 10, figs 4–4d. (v)1972 Paracyathus kangliaensis sp. n.: Floris, p. 60, pl. 3, figs 6A–9. 2000 Steriphonotrochus manorensis, Wells 1933: Löser, p. 74. Dimensions. d (adult)=8 x 14.5 mm, (juvenile)=4.5 mm; s (adult)=64, s (juvenile): 36; costae (adult)=64, (juvenile)=around 30; h=13.5– 18 mm. Description. Corallum elongated conical, elliptical in outline in later adult stages; septal arrangement rather irregular in juvenile stages, with about 30 extending to the columella in adult image; in late adult stages number of costae equal number of septa, in juvenile stages number of costae often smaller than number of septa; septa laterally granulate, marginally smooth; in corallite of around 7 mm in diameter 48 septa developed; around 60 septa are present in corallite of d (max) 10 mm. Remarks. The species B. kayserenesis (Vaughan, 1920), B. lloydi (Vaughan, 1920), and B. thomi (Vaughan, 1920), all of which were described from the Danian of the USA (Cannonball Marine Formation), are assumed to represent a more immature stage of the form B. manorensis (Table 4, figs 3a–c). The species B. kangliaensis from the lower Danian of Greenland closely corresponds to the more immature ontogenetical stage. Type locality of species. Paleocene of the USA (Cannonball Marine Formation). Distribution. Upper Maastrichtian-Paleocene of the USA (Navarro Formation, Texas; Cannonball Marine Formation), Lower Danian of Denmark (Greenland).
