ABIDA. 303 



A. frumentum castanea Gredler. ''Nearly of the size and 

 shape of elongata Essm., with which it lives, but beautiful 

 reddish brown. This extremely notable color-variety if not 

 a hybrid of frumentum and megacheilos extends only along 

 a fifteen-minute stretch between Nago and Torbolo, in the 

 Sarkathal, but is found in abundance here on the road walls, 

 as well as upon Mt. Brione" (Gredler). 



Described as a variety of P. frumentum, but it may belong 

 rather to A. Ulyrica. I have not seen it.

The shell is usually somewhat larger (than frumentum), 

 more slender, with the summit drawn out longer, and the 

 striation finer and irregular; a callous (behind the lip) is en- 

 tirely wanting (Rossm.). The angular lamella is slightly 

 forked in front, and is often almost continuous with the spiral 

 lamella. A quite small twin lamella runs inward from the 

 callous at the posterior angle of the lip. The palatal plicae 

 emerge further on the lip, and the sutural plica is longer than 

 in frumentum. There is sometimes a small infrapalatal plica. 



Length 10 to 11, diam. 3.5 mm. ; 10 to 11 whorls. 



Carinthia, Dalmatia, southern Tirol.
