ORCULA. 133 



(Gurnitzer Schlueht and in a Schlueht of the Windachwald). 

 The shortly conic shells there have average size of 5.4 x 2.95 

 mm. This is Orcula co-nica minor, new local form, H. von 

 Gallenstein in schedis (fig. 40). 



Among typical conica from two places in the Karawanken 

 (Grosser Suhagraben bei Maria Elend and Windischbleiberg) 

 there are specimens standing midway between the two species 

 in being more cylindric than typical conica and more conic 

 than typical dolium, with a weakly labiate peristome and two 

 thin, equally strong columellar lamellae reaching to the edge 

 of the peristome (as occurs exceptionally in 0. dolium) ; so 

 that it seems impossible to refer them with certainty to either 

 species (text-figs. 41, 42). The number in each place is very 

 small. Can it be that there are transitions between 0. dolium 

 and 0. conical 



Orcula doliolum (Brug.) var. (Vol. 27, p. 17). 



Valley of the Vantsch River, Darvaz, Pamir (Kaznakov). 

 "These specimens agree with those of middle Europe in size 

 and sculpture and differ from them only in that the shell is 

 quite cylindric (not broader above), and that the two colu- 

 mellar lamellae are more weakly developed and not visible in 

 a direct front view in the mouth. Wholly similar are many 

 specimens from Transcaucasia. The species has been reported 

 for Central Asia (Rosen, 1901) and is known from various 

 places in the mountainous part of Turkestan. It has been 

 recorded from Kopet-Dag in Transcaspia, Baron 0. von Rosen, 

 and from north Persia (0. Boettger 1898), so that it is easy 

 to make the connection with its occurrence in Transcaucasia 

 and Asia Minor. It is well known to extend thence over cis- 

 Caucasia (Retowski, 1914) and the Crimea (Lindholm 1926) 

 to southeastern and middle Europe. It is a pronounced moun- 

 tain dw^eller" (Lindholm, 1931, Abhandlungen der Pamir- 

 Expedition 1928, VIII, p. 43).
