 reflected. Length 4-4%, diam. 1^-1% lines (Kuester).

The accessory lamella between the angular and the end of 

 the outer lip is more developed than in illyrica or any form 

 of the frumentum series. The angular lamella approaches the 

 parietal rather closely. The spiral lamella is long, as in illy- 

 rica. The parietal lamella has a longer inward continuation 

 than I have seen in any other of the frumentum group. On 

 the last half-whorl the white lines over the palatal plicae are 

 conspicuous. The specimens examined are larger than the 

 types of Kuester, measuring from 10 mm. long to : length 11, 

 diam. 4 mm. ; 101/2 whorls. 



Figs. 12 and 15 are copied from Kuester. Fig. 16 from a 

 specimen from Mme. Paulucci, and figs. 13, 14 specimen from 

 Terver. 



It has often been considered a variety of frumentum, but it 

 is more distinct than any of the other forms.

The shell is minutely perforate, cylindric, the upper half or 

 third tapering to the obtuse apex ; cinnamon-brown (but vary- 

 ing from much darker to paler) ; finely striate. Whorls 

 slightly convex, the last rounded below, and showing whitish 

 lines over the internal plicae. Aperture brown within, the 

 teeth whitish. Angular lamella continuous with the spiral, 

 which penetrates as far as or a little beyond the parietal (fig. 

 11). A short twin-lamella within the lip-insertion. Parietal 

 lamella high in the middle, tapering towards both ends. 

 Columellar lamella a little stronger and longer than the sub-
