both, by the proportionately longer pedicle and its direction in rela- 

 tion to the spatula. 



Section Transylvanica Westerlund. 



Clausium nacreous-white; spatula bilobed, broad towards the 

 base, rapidly diminishing in width towards the pedicle, merging into 

 and continuous with the pedicle, concave ; outer margin short, solid, 

 and rounded, intercepted near the base by the orifice ; inner margin 

 long, continuous, and folded except at the lobe, which is raised, 

 solid, and often spirally produced ; pedicle narrow and sinuous, ter- 

 minating by fusion into the columella at the base of the penultimate 

 whorl, fusion opposite to the aperture of the shell. 



plumbea Rossmassler. — Clausium large, spatula deeply exca- 

 vated, outer lobe short, slightly produced, inner lobe narrow, 

 raised, very solid towards the base, then becoming deflected and 

 extended spirally. Kronstadt, Transylvania. Plate 6, figure 2. 



straminicoUis Parr. — Clausium very solid, spatula narrowly ex- 

 cavated, outer lobe short, not produced beyond the orifice which 

 is narrow, inner lobe thickened, deflected and spirally produced. 

 Butschetsch, Transylvania. Plate 6, figure 3. 



regalis M. Bielz.— Clausium solid, spatula somewhat deeply and 

 squarely excavated, outer lobe very short, only slightly produced, 

 inner lobe extremely solid, raised and thickened and greater in 

 width than in any other species. Lower slopes of N. Piatra 

 Mare, Transylvania. Plate 6, figure 4. 



angustata E. A. Bielz.— I have not seen examples of this species. 

 jickelii Kimakowicz. — I have not seen examples of the typical form, 

 var. occidentalis E. A. Bielz.— -Clausium small and ex- 

 tremely fragile, spatula not deeply excavated, outer lobe 

 very short, not produced at the orifice, inner lobe pro- 

 duced but not thickened except at the extreme end, 

 broad, and similar in this width of lobe to regalis Bielz. 

 Val Rosea, Petroseny, Transylvania. Plate 6, figure 5. 

 . deubeli Westerlund. — Clausium fairly solid, rather short, inner 

 /and outer margins nearly parallel, outer lobe short, slightly pro- 

 duced, inner lobe solid, raised, spirally deflected, orifice squarely 

 excavated. Behind Bacsfalu, Transylvania. Plate 6, figure 6. 



elegans E. A. Bielz. — Clausium similar to deubeli, but with a 

 rather longer spatula ; orifice very distinctly squarely excavated, 

 deeper cut and more central. Dumbroviciora Schlucht, Rou- 

 mania. Plate 6, figure. 7. , . 



canescens Parr. — Clausium small and solid, spatula narrow, outer
