198 TORNATINA. 



may at once be recognized in the top of each. The species seems 

 considerably to resemble Bulla (Tornatina) polita A. Adams, from 

 Manilla, but the lip is not posteriorly produced. (Wats.). 



T. MARINE Ten ison- Woods. Unfigured. 



Shell smail, ovate, thin, white, smooth and polished ; spire slightly 

 exserted ; whorls 5 ; nucleus situated vertically ; suture deeply 

 channelled ; aperture narrow, scarcely constricted in the middle, the 

 labrum acute, the columellar lip thickened and twisted in front. 



Alt. 5, diam. 2, spire hardly 1-5 mill. (T.-W.).

T. PACHYS Watson. PI. 24, fig. 33. 



Shell rather large, gibbously oval, being tumid in front and con- 

 tracted upwards, truncated above, where the edge is carinated and 

 furrowed, with an impressed top and a papillary apex. Sculpture : 

 Longitudinals the lines of growth are few, sinuous, and very 

 slight. Spirals round the edge of the impressed top is a rounded 

 keel, with an exterior strongish rounded-furrow, outside of which is 

 a narrow sharpish keel ; within the apical pore the whorls are 

 sharply keeled above the channelled suture ; the only other trace of 

 spiral striation is behind the outer lip, where the fresh shell shows 

 some trace of a spiral texture. Color horny yellowish-white. 

 Mouth club-shaped, large, the full length of the shell being a little 

 produced posteriorly, shortly curved across the body, ample in front. 

 Whorls 4, the earlier ones only indistinctly visible in the impressed 

 top ; the apex is papillary. Suture deeply channelled, with a sharp 

 keel above it; this keel runs out not above but on the edge of the 

 funnel-shaped top. Outer lip rises from the inner side of the apical 

 depression, and slopes flatly outwards, forming thus the patulous 

 opening of the funnel-shaped depression ; at the apical keel it is 

 angulated ; from this point it makes a convex sweep, which has a 

 slight-contraction about the middle ; it is patulous and somewhat 

 elliptical in front. Top nearly flat, only the outer lip rises slightly 

 above the level ; the apical depression is funnel-shaped, having a 

 wide converging mouth and a small, not deep hole in the middle, 

 with a papillary apex in the centre. Inner lip ; a broadish distinct 

 white glaze extends across the body, on which the curve of the lip 

 is very regularly convex on to the narrow, long, low and twisted
