AGARDHIA. 155 



Transsylvania, the territory of typical bielzi, as noticed by 

 Kiniakowicz, and found in a lot before me from the Rodna 

 Mts., one of which is drawn in pi. 16, figures 15, 16. It seems, 

 therefore, hardly worth recognition as a subspecies. 



la. A. bielzi romanica (Kim.). 



Striation of the shell much finer and less distinct. Colu- 

 niellar lamella placed very high, but little emerging and de- 

 cidedly obsolete. Parietal lamella rudimentary, scarcely indi- 

 cated. The lowest palatal [basal] fold is wanting, the two 

 others are markedly weaker than in the type form. Length 

 4.6, diam. 1.6 mm., 8% whorls (Kim.). 



Southern slope of the Transsylvanian Alps south of the 

 Tomoser Pass in Rumania and spreading over the Kronstadt 

 and Bodza Mountains.

Subgenus Agardhiella Hesse.

 195; for "die Sippe der A. truncatella." 



Agardhias in which there are no palatal folds; outer lip 

 tooth, parietal and columellar lamellae may be either present 

 or wanting; when an angular lamella is present it emerges 

 near the termination of the outer lip. The embryonic 1% 

 whorls are microscopically wrinkle-pitted, after which axial 

 riblets abruptly set in. Type A. truncatella. 



These forms occur from the Friuli to Transylvania and at 

 least as far south as Philippopolis in Rumelia. The species 

 and races seem to be somewhat numerous, but outside of Aus- 

 trian and Transylvanian collections, specimens are still rather 

 scarce. The local races have been little understood, but 

 Kimakowicz, Hesse, and especially Sturany and Wagner, have 

 worked most of them out satisfactorily.
