14 ORCULA. 



79 (Grimming, Alpe Lawinenstein, cliffs of Altausseer Lake, 

 Steiermark). 



Pupa pollonerce Pini, Atti. Soc. Italiana di Sci. Nat., xxvii, 

 1884, p. 79, fig. (Val di Non, Tirol) ; cf. Gredler, Nackrbl. d. 

 m. Ges., xvii, 1885, p. 38 (as a synonym of P. gularis var. 

 spoliata) . 



Distinguished by the palatal callus, from which, except in 

 var. spoliata, a lower-palatal fold runs inward. It is usually 

 more slender than other species of the region. 



0. gularis in the young stage has lamellae, that of the pari- 

 etal wall showing knots exactly as in 0. doliolum, according 

 to Reinhardt. 



2a. 0. gularis restituta (Westerlund). 



Two columellar lamella? long, strong, parallel, running to 

 themargn. Carinthia, Feestritz valley at Stein {Westerlund, 

 Fauna, iii, 1887, p. 85). 



2b. 0. gularis spoliata (Rossni.). PL 1, fig. 15. 



No palatal fold; neck more swollen (Bossm.). 



Tyrol Alps (Rossm.) ; Val di Non, Nonsberg, Tyrol, for P. 

 pollonercc). Central Carpathians. Galizian side of the Tatra, 

 Rosenberg and other places in the Waag valley (Reinhardt). 



A specimen from Dennberg, Tyrol, received from the Boett- 

 ger collection, is figured. It is but slightly swollen behind 

 the aperture, and measures, length 5.3, diam. 2.6 mm., 8^ 

 whorls. 



Gredler has shown that P. pollonerce Pini is identical with 

 spoliata. 



2c. Orcula gularis pseudodolium "Wagner. 



Shell larger, more ventricose, more strongly striate than in 

 the typical form from Carinthia, and thus strikingly recalling 

 Orcula dolium. Also the upper columellar fold is stronger, 

 emerging further, and also distinctly visible in a direct view 

 in the aperture ; often as strongly developed as in 0. dolium 

 Drap. The palatal callus is as strong as in 0. gularis spoliata 

 R., but with a short, fold-like extension; the peristome more 

 expanded. Length 7, diam. 3 to 3.5 mm. (Wagner).
