Helix subrugata Reeve, 1852

Pl. 11, fig. E

Reeve, (1851–1854) 1852. Conchologia iconica, 7: species 773, pl. 128, fig. 773.

Type material: Syntypes (2), NHMUK 1982236 (dry shell material); ex Museum Cuming (Acc. no. 1829) .

Label details: ‘Australia’

Type locality: ‘Clarence River, New South Wales’ ( Pfeiffer 1853a: 56, 1853d: 259); incorrectly stated as ‘New Zealand’ by Reeve (1852 [in 1851–1854]: species 773).

Previous illustrations of type material: Reeve (1852 [in 1851–1854]: pl. 128, fig. 773), Pfeiffer (1853 [in 1852–1860]: pl. 156, figs. 9–10).

Remarks: Helix subrugata Reeve, 1852 and H. subrugata Pfeiffer, 1853 are based on the same type material. Pfeiffer evidently intended to publish the original description of this species in the Proceedings of the Zoological Society of London issue for 1851 (see Reeve 1852 [in 1851–1854]: species 773; Pfeiffer 1853a: 56), but publication was delayed until 1853 ( Pfeiffer 1853a: 56; 1853d: 259; 1853 [in 1852–1860]: 468, pl. 156, figs. 9–10), and was pre-empted by Reeve (1852 [in 1851–1854]: species 773). Helix subrugata is an eastern Australian species, as stated by Pfeiffer (1853a: 56, 1853d: 259). Reeve’s (1852) record of this species from New Zealand was in error, and not consistent with the label details of the type material. Helix subrugata Pfeiffer, 1853 [= H. subrugata Reeve, 1852 ] is the type species of Thalassia Albers & Martens, 1860 [non Gistl, 1848, in Vermes] and Nitor Gude, 1911 .

Current Taxonomy: Listed as Nitor subrugata (Reeve, 1852) by Smith (1992: 239) and Stanisic et al. (2010: 284). Helix subrugata Pfeiffer, 1853 is a junior primary homonym and an objective junior synonym of Nitor subrugata (Reeve, 1852) .

Distribution: coastal eastern Australia, in the vicinity of the Queensland—New South Wales border ( Smith 1992: 239; Stanisic et al. 2010: 284).
