Genus Sorites Ehrenberg 1839

Sorites marginalis (Lamarck) = Orbulites marginalis Lamarck 1816, p. 196 [Plate 2, Fig. 7]. Müller-Merz & Lee (1976), fig. 1. “ Parasorites marginalis ” Jones (1994) , p. 30, pl. 15, figs. 1–5, 5. Javaux & Scott (2003), p. 22, fig. 5.5. Araujo & Machado (2008), p. 38, pl. 2, fig. 1. Note: Amphisorus hemprichii Ehrenberg 1839 of authors. Sorites marginalis has later been designated as type species for the genus Sorites ( Loeblich & Tappan 1988: p. 382) . Sorites marginalis has been designated as type species for the genus Sorites ( Loeblich & Tappan 1964: p. C496). The coiling direction of the initial spire is the same as in the younger part of the test of Sorites marginalis . The spiral part is, however, detached in the similar species Broeckina orbitoloides ( Hofker 1930) . The latter also shows a complete encirculation of chambers younger than 19 (e.g. Hallock & Peebles 1993, pl. 2, fig. 5), which happens later in Sorites marginalis .
