Helix urnula Reeve, 1854

Pl. 9, fig. H

Reeve, (1851–1854) 1854. Conchologia iconica, 7: species 1306, pl. 189, fig. 1306.

Type material: Syntypes (3), NHMUK 1966136 (dry shell material); ex Museum Cuming (Acc. no. 1829) .

Label details: ‘ urnula Pfr. New Zealand’

Type locality: ‘New Zealand’ (Reeve 1854 [in 1851–1854]: species 1306).

Previous illustrations of type material: Reeve (1854 [in 1851–1854]: pl. 189, fig. 1306), Tryon (1885 [from Reeve 1854]: pl. 26, fig. 14).

Remarks: Helix urnula Reeve, 1854 and H. urnula Pfeiffer, 1855 are based on the same type material. Pfeiffer’s original description in the Proceedings of the Zoological Society of London issue for 1854 was not published until January 1855 ( Sclater & Waterhouse 1893), and was pre-empted by Reeve’s description published in July 1854. Authorship previously attributed to Pfeiffer (e.g., Pfeiffer 1859: 8; Hector 1873: 4; Hutton 1880: 22; Suter 1913b: 784; Powell 1930: 52; Powell 1979: 343; Spencer et al. 2009: 218), but Reeve (1854) has priority. Helix urnula Reeve, 1854 [= Helix urnula Pfeiffer, 1855 ] is the type species of Wainuia Powell, 1930 , by original designation.

Taxonomy: Wainuia urnula (Reeve, 1854) n. comb. is accepted here as an available valid name. Helix urnula Pfeiffer, 1855 is a junior primary homonym and an objective junior synonym.

Distribution: New Zealand; southeastern North Island, from Wellington to Waikaremoana, and Kapiti Island ( Powell 1979; Efford 1998).
