Show 1883.] DR. o. BOETTGER O N N E W CLAUSILIA. 341 Sect. Alinda, ex rec. Bttg. 46. CLAUSILIA DENTICULATA (Olivier), Voyage, i. p. 297, tab. 17. fig. 19. Var. SPRATTI, m. Differt a typo t. magis turrita, isabellina, anfr. 14-15, magis protracta, sinulo distinctiore, elevato, labio sinistro denticulis omnino carente. Alt. 18-g-, lat. 3^ mm.; apert. 3\, lat. apert. 2\ mm. Sab. Island of Kos (Spratt). This fine variety differs peculiarly from the type of the islands Andro and Tino by the complete absence of denticulation of the outer lip. Sect. Idyla, v. Vest. 47. CLAUSILIA THESSALONICA, K., var. euboica, Bttg. Nachr.- Blatt. d. deutsch. malakozool. Ges. 1880, p. 50. Admiral Spratt collected this variety, which was till now only noted from Hagia Anna in the north of Eubcea, on Mount Stoura, South Euboea, in 2000 feet alt. Here the form has a more greenish-brown colour, an interrupted peristome, and alt. 14, lat. 3^ mm. Now, in studying again my rich material of this group, I find that also C. spreta, K., from the Prinkipo Islands and from Brussa in Natolia, must be regarded as only a variety of C. thessalonica, K. Sect. Oligoptychia, Bttg. 48. CLAUSILIA SOWERBYANA, Pfr. P.Z.S. 1849, p. 141. This rare, always decollated species must be ranked in the section Oligoptychia, where it represents a peculiar little group (Sprattia) connecting the subsections Armeniaca, Bttg., with Scrobifera, Bttg., and being well characterized by the truncature of the apex and by the acutely striated shell. Admiral Spratt found this magnificent shell in Evder Khan near Adalia, Pamphylia. 49. CLAUSILIA EUSTROPHA, Bttg., 22. u. 23. Bericht d. Offen-bacher Vereins f. Naturkunde, 1883, p. 210. This species, only known till now from the island of Skyatho and from North Eubcea, has been collected in small but typical specimens by Admiral Spratt at the akropolis of Opus, Phthiotis. Alt. 13|- 14^, lat. 3 mm. 50. CLAUSILIA BICRISTATA, Rssm. Iconogr. ii. fig. 619. Var. TETRAGONOSTOMA, P., Boettger in 22. u. 23. Ber. d. Offenb. Ver. p. 213. Has been collected by Admiral Spratt on Mount Oktonia, south of Koumi, Eubcea, at 2000 feet alt., in a form of alt. 17\, lat. 34> mm., alt. apert. 3|, lat. apert. 3 mm., which agrees well with f. ku-mensis, Bttg., but differs in having the same smooth median whorls as the typical form of tetragonostoma, P., from Mount Delphi. |
