Notes on some Surinam land snails

During my stay in Surinam (Dutch Guiana) in the first three months of 1963 most of my time was devoted to the study of the marine Mollusca, on which I shall report later. Now and then, however, I had an opportunity of collecting non marines. The following notes are the result of the study of some of the land snails in the material I collected. SUBULINIDAE Leptinaria (Luntia) insignis (E. A. Smith) Luntia insignis Smith, 1898, Journ. Conchol. 9: 28, fig. 8 (Trinidad); Pilsbry, 1906, Man. Conch. (2) 18: 218, pl. 40 fig. 7; Hummelinck, 1940, Studies Fauna Curaçao &c. 2: 98 (Aruba); 3: 115, 116 (Aruba); Morrison, 1943, Nautilus 57: 48 (British Guiana). Varicella clappi [non Pilsbry], Meeuse & Hubert, 1949, Basteria, 13: 18, pl. 3 fig. 15 (greenhouse in Botanical Gardens, Utrecht, Netherlands). Varicella cf. clappi, v. R. Altena, 1960, Basteria 24: 50 (Tambaredjo, Surinam). Leptinaria (Luntia) insignis, Thiele, 1931, Handb. syst. Weichtierk. 1 (2): 552; Haas, 1962, Studies Fauna Curaçao &c. 13: 53, pl. 11 fig. I, J (Saba). The figure published by Haas enabled me to identify this species which Hubert & Meeuse thought to be Varicella clappi Pilsbry, and which I recorded from Surinam in 1960. Recently I had an opportunity of confirming this revised identification by comparison of Surinam specimens with the holotype of the species in the British Museum (Natural History). I found Leptinaria insignis in two more localities in Surinam, viz., in the Botanical Gardens of Paramaribo, and at the base of the ruins of the synagogue at Jodensavanne, on the Surinam River, some 50 km south of Paramaribo. Morrison (1943) states that in British Guiana the species belongs to 'the smaller species of land mollusks that were found mostly on Kyk-over-
