39. Clausilia arcadica, Bttg., Mon, Claus.-Sect. Albinaria, 

 p. 101, tab. 3. fig. 7 {maculosa, subsp. arcadica, Bttg., olitn). 



For this fine-coloured shell I can now add the localities Mamoussd 

 near Vostitsa {Consul Nik. Koncmcnos), Megaspileo near Kalavryta 

 {Konemenos), Ijoth localities in the north of the Morea, and Mount 

 Cylline, Sparta {Thiesse). Having in my hands more copious material 

 than during the publication of my dissertation on the section Albi- 

 naria, I can now with more certainty give my opinion on the specific 

 value of this form. The diagnosis of this species may be : — 



Discr spans a C. maculosa. Desk., typica t. majore, graciliore, 

 temnore, strigis corneo-fuscis distinctiorihus variegata, spira 

 longe attemiata. Anfr. ll-\2h, planiores, iiltlmus hasi di- 

 stincthis gihhosa, obsolete sulcaius, ante aperturam validius 

 costulafo-striatus. Apert. minor, regulariter ovata ; perist. 

 parum expansum, vix aut non labiatum. Lam. .supera vel 

 parva vel obsoleta, recedens ; subcolumcllaris oblique intu- 

 enti aut vix aut non conspiciia ; lunella deorsmn scepe obsoleta. 

 Alt. 16f-20i lat. 3|-5 mm.; alt. apert. 3^-41 lat. apert. 

 2-2—35 mm. 



Hab. Interior of North and Central Morea. 



40. Clausilia schuchi, Rssm., see Boettger, Mon. Claus.-Sect. 

 Albinaria, p. 102. 



Var. oscARii, Thiesse, MS. (Plate XXXIV. fig. 16.) 



Differt a typo t. maxima, valde ventriosa, lactea unicolor, vel raro- 

 strigillata vel punctata, anfr. 11-12, mediis fere semper Icevi- 

 bus, perist, magis expanso. Alt. 19-19|, lat. A^-b^ mm. ; alt. 

 apert. A\, lat. apert. 4 mm. 

 Hab. Vitylo and Mount Cylline, Sparta (Thiesse). 

 This curious form cannot be separated from the little brown- 

 striped typical G. schuchi, Rssm., of Navarino, although it has a very 

 peculiar aspect by its great size, uniform colour, and ventricosity ; 

 but the plaits and lamellae of the mouth and the apparatus claustrahs 

 are absolutely identical in both forms. 



41. Clausilia incrustata, n. sp. (Plate XXXIV. fig. 17.) 



Fernff. C. contaminatse, Bssm., var. solutas, Motiss., sed sub epi- 

 dcrmide lactea fusca ; anfr. ultimus gibhere umhilicali distinc- 

 tiore, magis compresso instructus^proj^e aperturam suhconstric- 

 tus ; apert. minor, angustior, sub sinulo magis compressa; 

 2)erist. breviter expansum, acuium, calloso-labiatum ; lam. 

 supera longissima, acuta; infera multo altior, semilunaris, 

 subcolumellaris, oblique intuenti non conspicua. Alt. 151-] 6, 

 lat. 4-5 mm. ; alt. apert. 3-ij-, lat. apert. 3-3j mm. 



Hab. Island of Servi or Elaphonisi {Spratt). 



This very peculiar shell is distinguished from C. contaminata, 

 Rssm., by its high and long lamella supera, by its very strong 

 lamella infera, and by the totally concealed lamella subcoluraellaris.
