the Transylvanian Alps, south of Tomoser Pass, in Rumania 

 (Kim.). 



Torquilla frumentum Drap. var. hungarica Kim., Ver- 

 handl. u. Mittheil. des Siebenbiirgischen Vereins fur Natur- 

 wiss. in Hermannstadt, xl, 1890, p. 102. Pupa frumentum, 

 and P. f. var. illyrica in part of Clessin and Westerlund. 



In a large series from Nandor received from E. A. Bielz, 

 the aperture is exactly as in frumentum, but the callous be- 

 hind it is weaker or wanting, and the striation is finer. The 

 shorter shells, about 6 mm. long, have the upper half conic ; 

 the longer ones, 8 mm., are markedly cylindric. While not 

 strongly differentiated, it appears to be distinguishable as a 

 peripheral southeastern race. 



Abida frumentum pachygastra, (Ziegl., Rossm.). PL 42, figs. 

 7, 10, 11. 



Shell cylindric-fusiform, acuminate, ventricose, corneous-

 stome reflected; the throat many-folded: two folds on the 

 columella and on the parietal wall, in the palate five or six. 

 Length 5, diam. 1% lines; whorls 11 (Rossm.).

This form is more glossy and less distinctly striate than A. 

 frumentum; there is no whitish callous behind the lip; the 

 angular and parietal lamellae are a little further apart, the 

 parietal lamella is less regularly arcuate, viewed from below ; 

 the spiral lamella is longer and slightly curved (fig. 7) . Kues- 

 ter (1875) has argued that it differs specifically from frumen- 

 tum, which may be true, but most authorities have reckoned 

 it a variety. Specimens from Riva measure 8.5 to 10 mm. 

 long. Rossmassler's figures are copied in pi. 42, figs. 10, 11.
