Sect. Alinda, ex rec. Bttg. 



46. Clausilia denticulata (Olivier), Voyage, i. p. 297, tab. 

 17. fig. 19. 



Var. sPRATTi, m. 



Difert a typo t. magis turrita, isabellina, anfr. 14-15, apert. 

 magis protracta, similo distinctiore, elevato, labia sinistro peri- 

 stomatis denticulis omnino carente. Alt, 18^, lat, 3^ mm.; alt. 

 apert. 3j, lat. apert. 2^ mm. 

 Hab. 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. euhoica, 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 Eubcea, 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, nmst 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., vii\.\\ 8crobifera, 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., Bocttgcr 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. 1 /i, lat. 3^ 

 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.
