8. FAUXULUS GLANVILLIANUS (Ancey). 



Shell ovate-subconoid, imperforate but with a long rima- 

 tion, thin, somewhat shining, whitish, pellucid, sinistral. Spire 

 conoid-subventricose, with convex outline, smooth and a little 

 obtuse at the summit. Whorls 8*4 to 8%, regularly and 

 gradually, slowly increasing, but slightly convex, separated 

 by a simple, not deep, suture, obliquely, arcuately and reg- 

 ularly striate, the last whorl more convex, tapering, com- 

 pressed-carinate in front, around the place of the umbilicus; 

 striae suddenly breaking off in the middle of the last whorl, 

 yet visible below, the median space simulating a narrow angle. 

 Aperture upright, irregular, strongly ringent, ascending 

 above, subrhombic, whitish, obstructed and nearly closed by 

 lamellae as follows: one strong, entering parietal; 4 palatals, 

 the upper [= angular lamella] large, at the superior angle, 

 oblique, and outside prominently separated from the rest by 

 a lobe which has the appearance of being tubular within; 

 second and third subequal, the lower strongly twisted; 3 

 columellar lamellae, strong and subequally spaced. Peristome 

 thickened, subexpanded, the lamellae reaching to the margin, 

 the outer margin lobed above, then nearly straight, and 

 slightly angled near the base, then running straight, basal 

 margin strongly angular, columellar margin long, flatly 

 straight, the margins continuous by an appressed parietal cal- 

 lous. Length 4, diam. 2, alt. of aperture 1% mm. (Ancey).

Mr. Ancey 's upper palatal lamella is the angular lamella, 

 as Mr. Burnup pointed out. It is separated from the palatal 

 plicae by the sinulus or "lobe." His second and third, de- 

 scribed as subequal, are the suprapalatal and upper palatal 

 plica, and his lower is the lower palatal plica. Nothing is
