Helix compressivoluta Reeve, 1852

Pl. 4, fig. C

Reeve, (1851–1854) 1852. Conchologia iconica, 7: species 791, pl. 130, fig. 791.

Type material: Syntypes (3), NHMUK 1996113 (dry shell material); ex Museum Cuming (Acc. no. 1829) .

Label details: ‘N. Zealand’.

Type locality: ‘New Zealand’ (Reeve 1852 [in 1851–1854]: species 791).

Previous illustrations of type material: Reeve (1852 [in 1851–1854]: pl. 130, fig. 791); Tryon (1885 [from Reeve, 1852]: pl. 26, fig. 28).

Remarks: Helix compressivoluta Reeve, 1852 and H. omega 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 Pfeiffer 1853a: 34), but publication was delayed until 1854 ( Pfeiffer 1854a: 56), and was pre-empted by Reeve (1852 [in 1851-1854]: Species 791).

Current Taxonomy: Listed as Flammoconcha compressivoluta (Reeve, 1852) by Solem et al. (1981: 480) and Spencer et al. (2009: 215). Placement in Flammoconcha Dell, 1952 requires re-evaluation.

Distribution: New Zealand; southern North Island ( Suter 1913b; Powell 1979).
