Notes on Bulimulidae (Gastropoda, Euthyneura), 7. Anatomy and histology of Simpulopsis (Simpulopsis) miersi Pfeiffer, 1856

During recent years a group of Brazilian malacologists has contributed substantially to our knowledge of Brazilian Bulimulidae. The second author has been fortunate enough to have had the opportunity to visit some of these specialists twice and to establish a close cooperation. This paper is the second in our joint series treating several species in greater detail. The first paper in this series is by Breure & Dos Santos Coelho (1976). Simpulopsis (Simpulopsis) miersi Pfeiffer, 1856 (figs. 1-7, pls. 1, 2) Simpulopsis miersi Pfeiffer, 1856: 260; Pfeiffer, 1859: 800; Pfeiffer, 1868: 21; Pfeiffer, 1876: 28; Pfeiffer & Clessin, 1881: 229; Pilsbry, 1899: 218; Morretes, 1949: 162.
