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 Eossmaessler'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 illyrica. 



Torquilla, triticum Ziegler, from Dalmatia, was mentioned 

 by Porro, 1839 (with the undefined varieties elongata and 

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

 Stabile, whose diagnosis and figures show it to be identical 

 with illyrica. The following dimensions are given by him. 



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



Length 9, width 3y 2 mm. (var. parva Stabile, Bianza, Lom- 

 bardy). 



Length 12, width 3^2 mn i. (var. magna Stabile). 



The following described varieties are referable to illyrica 

 as races or local forms of some degree. 



A. illyrica 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 Wiudischgraben near Ferlach in Carinthia. This form 

 is P. adjuncta Zgl. (Rossm.). 



A. illyrica minor Eossm. 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 cliffs, especially on the Grossgallenberge and 

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