Var. antiochensis, n. v. A broad form from Antioch 

 (Hesse coll., from Berlier) which Hesse has identified as var. 

 nitida Mouss. (Archiv f. Molluskenkunde, vol. 59, 1927, p. 

 177) has no lower-palatal fold within. In two of the three 

 examples there are two cord-like lamellas between the parietal 

 lamella and the suture (pi. 19, figs. 10, 10a). In the third, 

 only one lamella is there (PI. 19, fig. 11). 



Length 9.8, diam. 4.6 mm. (Fig. 10, 10a, type). 



Length 10.5, diam. 5.0 mm. 



Length 9.5, diam. 4.8 mm. (Fig. 11). 



Whether this is really var. nitida of Mousson is not material, 

 since that name cannot be used, being a homonym.

Vol. 27, p. 36. In this form there is a very small lower- 

 palatal fold, which is visible externally as a short white mark- 

 ing above the umbilical rima in fresh shells (fig. 13a), and 

 internally appears as a very low callous fold (fig. 12). The 

 specimens figured are from Aleppo, Hesse coll., and were 

 recorded as Orculella orientalis in Archiv f. Molluskenkunde, 

 vol. 59, p. 176, 1927.

I am inclined to rank this as a distinct species, differing 

 from V. ventricosa by the constantly longer spire. The follow- 

 ing appears to be a synonym.
