This form has generally been ranked as a variety of A. 

 frumentum, but possibly the relations of the various forms 

 may appear clearer by giving it specific standing, as Com- 

 mandant Caziot holds. This author (t. c., p. 156) has wholly 

 misunderstood Rossmaessler's plain statement that P. callosa 

 Ziegler (undescribed) is typical frumentum, and the other 

 Illyrian form which Ziegler thought was frumentum is the 

 new variety Ulyrica. 



Torquilla triticum Ziegler, from Dalmatia, was mentioned 

 by Porro, 1839 (with the undefined varieties elongata and 

 curt a Z.), and by Villa, 1841, but it was first described by 

 Stabile, whose diagnosis and figures show it to be identical 

 with Ulyrica. The following dimensions are given by him. 



Length 10, width in the middle 3% mm. (triticum). 



Length 9, width 3% mm. (var. parva Stabile, Bianza, Lom- 

 bardy) . 



Length 12, width 3% rnm. (var. magna Stabile). 



The following described varieties are referable to iUyrica 

 as races or local forms of some degree. 



A. Ulyrica elongata Eossm. PL 45, fig. 4. Shell larger, 

 darker, rather cylindric, pointed, without cervical callous, the 

 folds strongly developed. Very abundant on a low, shrub- 

 covered breastwork, Passeggio a S. Andrea, near Triest; also 

 from Windischgraben near Ferlach in Carinthia. This form 

 is P. adjuncta Zgl. (Rossm. ) . 



A. Ulyrica minor Rossm. PI. 45, fig. 3. Shell smaller, 

 weaker, with the palatal plicae not very well developed, gener- 

 ally only the median two fully developed, and without a cer- 

 vical callous. I found this form on the Karst between Op- 

 china and Sessana, under limestone blocks, and near Laibach 

 on limestone din's, especially on the Grossgallenberge and 

 near Verbleine, at the last place in company with var. Ulyrica.
