Type material of land snails (Mollusca: Gastropoda) described from New Zealand by taxonomists in Europe and North America between 1830 and 1934, and the history of research on the New Zealand land snail fauna from 1824 to 1917 Author Brook, Fred J.

A Gray, 1850, Proceedings of the Zoological Society of London, 17 (1849): 164. Type material: Lectotype (here designated), NHMUK 1849.12.3.86; paralectotype (1), NHMUK 1849.12 .3.87 (dry shell material). Label details: ‘N.Z. Major Greenwood’. Type locality: ‘Auckland’ (Gray 1850: 165). Remarks: The original description of this species, which was reproduced by Gray (1851: 64) , was based on material collected c. 1847–1849 at or near Auckland , by Major Joseph Greenwood, and sent to the British Museum. There are apparently no previous illustrations of type material from the British Museum collection. A shell figured by Reeve (1852 [in 1851–1854 ]: pl. 131, fig. 799; also see Tryon 1886 : pl. 62, fig. 41) was from H. Cuming’s collection, and there is no evidence to indicate that it was from the type series of celinde . Our examination shows that NHMUK 1849.12.3.86–87 contains two species. The specimen illustrated here in pl. 3, fig. A, which matches Gray’s original description of celinde , and corresponds to New Zealand workers’ interpretation of this species (e.g., Suter 1913b: 656 , pl. 26, figs. 4, a, b; Cumber 1967c: 65 , figs. 3 A–F, 4 E–F), is here designated as the lectotype of Nanina ? celinde Gray, 1850 . The second specimen in the type lot appears to be Therasiella tamora (Hutton, 1883) . Nanina ? celinde Gray, 1850 is the type species of Therasiella Powell, 1948 , by original designation. Current Taxonomy: Listed as Therasiella celinde (Gray, 1850) by Powell (1957: 118 , 1979: 311 ), Cumber (1967c: 65) and Spencer et al . (2009: 216) . Distribution: New Zealand ; northern North Island ( Cumber 1967c ; Powell 1979 ).
