1883.] DR. O. BOETTGER ON NEW CLAUSILI^. 329 



The var. strictecostata, Bttg. (Mon. d. Claus.-Sect. Albinaria, 

 p. 28, t. i. fig. 6), has been found by Admiral Spratt in Sphakia, 

 south of Crete, in a nearly typical specimen. One did not yet 

 know till now any sure locality for this Cretan form, well distinguished 

 from G. tenuicostata typica by the costation of the neck, whose 

 ribs are not at all stronger than in the median whorls, and by the 

 deep-lying spiral lamella, which does not approach the lamella supera. 

 Alt. 171-181, lat. 3|-4 mm.; alt. apert. 4, lat. apert. 2-2-3 mm. 



10. Clausilia CANDIDA, Pfr. p. Z. S. 1849, p. 135. 



This species, specimens of which Admiral Spratt found near 

 Khania, island of Crete, is absolutely identical with C. straminea, 

 Ad. Schmidt, System, d. europ. Claus. 1868, p. 91. 



11. Clausilia aphrodite, n. sp. (Plate XXXIII. fig. 3.) 



Peraff. C. arthurianae, Blanc, sed soi-dide brunnea, penitus albido- 

 costulata, spira exserta validiusque concave producta, apiee con- 

 colori. Anfr. 12|, exceptis duobus primis confertim capillaceo- 

 costulati nee striati, costulis anfr. idtinii antice vix validioribus. 

 Apert. apparatnsque claustralis affims, sed peristomate superne 

 magis soluto, faucibus hepaticis ; lam. supera minus alta, infera 

 vel striata vel subconcava nee semicirculari oblique ascendente. 

 Cceterum C. arthuriause simillima, sed plicis lamellisque omnibus, 

 ut videtur, minus validis acutisque. Alt. 19, lat. 4g mm.; alt. 

 apert. 4|, lat. apert. 3g mm. 

 Sab. Pass over Tvlisso near Megalokastron, island of Crete 

 (Spratt). 



This form is easily distinguished from C. arthuriana, Blanc, by 

 the brown colour and the white or grey ribs of its shell, whilst 

 C arthuriana, from Spiualunga island, Crete, is qnite isabel-coloured 

 and only very finely striated. So the new species has more the ap- 

 pearance of C. liippolyti, Bttg., from Mount Ega, Crete ; but it is not 

 spotted like that, and has a more complicated apparatus claustralis. 



12. Clausilia xHiESSEiE, Bttg. (Plate XXXIII. fig. 4.) 



Nachr.-Blatt d. d. Malakozool. Ges. 1880, p. 48. 



I give here a drawing of this fine shell, not yet figured, which 

 seems to occur not rarely in Akarnauia, Morea {Dr. Theod. Krueper) 

 and in the neighbourhood of Patras, Morea {Thiesse and Consul 

 Nik. Konemenos). 



13. Clausilia bigibbosa, Charp. Zeitschr. f. Malak. 1847, 

 p. 143. 



I possess in my collection the typical form of this species from 

 Natolia. It measures, alt. 15|-20|, lat. 4-4| mm. 



F. MAJOR, m. Ti/po major robust ior que, anfr. tertio usque ad 

 sextum distantius costulato-striatis, crista cervicis exteriore 

 magis geniculata, miiitis rugosa. Alt. 22, lat. 5 mm. ; alt. 

 apert. 5, lat. apert. 4 mm. 



Hub. Arsa, valley near Xanthus, Lycia (Spratt).
