148 AGARDHIA. 



There are three of these, and perhaps a fourth close to the 

 suture. 



A specimen collected by Baily at Rapallo measures: length 

 3.7, diam. 1.45 mm. ; &y 2 whorls, being smaller than Pollonera 

 indicates. The heavy but adnate parietal callus is a promi- 

 nent feature. The parietal lamella is stronger than in bipli- 

 cata. 



5. Agardhia biplicata (Mich.). PI. 16, figs. 1, 2. 



Shell lengthened, cylindric, pellucid, glossy glabrous, urn- 

 bilicate, whitish. Nine nearly flat whorls, the upper ones 

 small, the rest equal. Aperture triangular; columella with 

 one fold, inner lip one fold, outer lip swollen ; peristome re- 

 flected, white. Apex very obtuse. Length 2y 2 lines, diam. 

 % of a line (Michaud) . Michaud adds that there are also two 

 folds within the lateral border of the aperture. 



Shell cylindric, umbilicate, pellucid, subglabrous, obtuse at 

 the apex, under a lens slightly striatulate. Whorls 8 to 10, a 

 little convex, the last somewhat compressed at base, obtusely 

 crested around the circular umbilicus ; suture deep. Aperture 

 suboblique, subtriangular, rounded below; peristome paler, 

 reflected, interrupted, the margins connected by a callus. 

 One strong emerging parietal lamella, continued very far in- 

 ward, above it a conic supplemental denticle situated deep 

 within. One columellar lamella strong, transverse, situated 

 high. Outer lip having a conic tooth. Four palatal folds, of 

 which the lower and upper are rudimentary and deep within, 

 the second and third lamelliform and produced towards the 

 margin. Length 4^2, diam. iy 2 mm. (Pollonera) .
