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



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

 near Vostitsa (Co7isnl Nik. Konenu'nos), Megaspileo near Kalavryta 

 {Koncmenos), both 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 : — 



Discrepans a C. maculosa. Desk., typica t. majore, graciliore, 

 tenitiore, strigis corneo-fuscis distinctiorihns variegata, spira 

 longe attennata. Anfr. l\-\2\, planiores, ultimus hasi di- 

 stinctius gihbosa, obsolete sulcatus, ante aperturam validius 

 costulato-striatus. Apert. minor, regidariter ovata ; jperist. 

 parum expansum, vix aid nan labiatum. Lam. .siipera vel 

 parva vel obsoleta, reccdens; sicbcolumcllaris oblique i)itu- 

 enti ant vix ant non conspicua ; lunella deorsum scepe obsoleta. 

 Alt. 16-|-20i lat. 3g-5 mm.; alt. apert. 3^4|-, lat. apart. 

 2-2—35 mm. 



Hab. Interior of North and Centi'al Morea. 



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

 Albinaria, p. 102. 



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



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

 strigillata vel j)vnctata, anfr. 11-12, mediis fere semjjer Icevi- 

 bus, perist. magis expanso. Alt. 19-19|, lat. 4f-5|^ mm.; alt. 

 apert. 4^, lat. apert. 4 mm. 

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

 This curious form cannot be separated from the little brown- 

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

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

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

 are absolutely identical in both forms. 



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



Peraff. C. contaminatse, Bssm., var. solutaj, Mouss., sed sub epi- 



dcrmide lactea fusca; anfr. tdtimns gibbere iimbilicali d/stinc- 



tiore, magis compresso instructti,s,p)rope aperturam subconstric- 



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



perist. breviter expansum, acutum, calloso-labiatum ; lam. 



supera lonc/issima, actda; infera midto altior, semilunaris, 



subcolumetlaris, oblique intuenti non conspicua. Alt. 1.5^16, 



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



Hal). 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.
