Nausithoe simplex (Kirkpatrick, 1890), comb. nov. (Figs 1–4) Stephanoscyphus simplex Kirkpatrick 1890: 14 (description), Pl. III, fig. 2 (tube), fig. 2a (cusps) [the species was attributed to G.J. Allman, but no published description or manuscript is available]. Tubularia cornucopia : Broch 1916: 29 [not Tubularia cornucopia (Bonnevie, 1898)] [specimens not seen]. Stephanoscyphistoma simplex : Jarms 1990: 11 [mention as a collective group]. History.— As mentioned by Kirkpatrick (1890: 14, footnote), his “bottle” of specimens was labelled with a species name ( Stephanoscyphus simplex ) that he attributed to G.J. Allman. Kirkpatrick noted, however, that he “.had not seen a published description of that species”. While studying the cnidarian collection at the NHM we found a small vial (NHM 1878.3.26.11) containing four stephanoscyphistomae. The vial was promptly recognized as taxonomically important because data on the label could be linked to the above account of Kirkpatrick. Based on that evidence, but given our inability to distinguish which of the syntypes was the specimen figured by Kirkpatrick (1890, Pl. III figs 2, 2a) (Fig. 1), we selected one of the better specimens from the series and designated it as the lectotype (ICZN 1999, Article 74). Material examined.— Syntypes (NHM 1878.3.26.11) collected in the North Atlantic (south of Greenland, 56º11’N, 37º41’W) by H.M.S. Valorous , probably in 1875, depth 1450 fathoms (~ 2650 m). Description of lectotype.—NHM 1878.3.26.11a (Fig. 2). Solitary polyp (4.18 mm long), with light-brown periderm tube, small basal disc for attachment (0.46 mm diameter) and Formquotient 0.138. D/L 2mm 0.16, and at the aperture 0,58 (Table 1). Tube surface with a pattern of transverse rings (4-5 rings/0.4 mm) with longitudinal striations, characteristic of Nausithoidae. The tube has only one whorl of internal cusps, arranged as two larger and two smaller perradial cusps. The internal cusps are rectangular. Description of species.—Solitary polyps (4.18–4.56 mm long, n = 3), with ...
