Long. 7, lat. 4 mm. 



A highly ornate little Faula^ near F. Glanvilleana, Ancey, 

 but of considerably larger size. The specimens before us are 

 unfortunately not in very good condition, but happily the 

 mouth-processes in one are quite perfect. The shell is tur- 

 binate or pyramidal, subrimate, sinistral^ much attenuate 

 towards the apex, nine-whorled (inclusive of the two tumid 

 apical) ; the whorls are canaliculate at the sutures and have 

 the appearance of tiling, each superini))ending the other; they 

 are rudely lirate, the lira^ close, incurved ; the last whorl is 

 short ; aperture rhomboid ; outer lip white, wrinkled, with 

 nine plaits or teeth — of these the parietal plicre (2) and the 

 basal (2) are long, thin, and deep-seated, and very similar, as 

 are the two columellar jdaits, the labial teeth (two), and one 

 small columellar ; one of the labial comes very near being 

 a plait.
