Shell ovately globose, solid, glassy ; sculpture microscopic transverse striae ; colour pearly white ; spire moderately high, sides rounded ; apex very blunt; suture linear ; whorls 4|, flatly convex ; aperture circular, vertical; peristome solid, sinuate on upper outer margin, when viewed from the side, with a slot at the suture ; the columellar margin broad, cut off from the peristome by a well-marked sinus. Size: maj. diam. 2*7 ; alt. axis 4*3 millim. Hub. Busan Hills (A. Everett). Only one specimen of this very disti ict species was found. It is noticeable for its small size and white colour.

Size: maj. diam. 3*0; alt. axis 6*9 millim. Hab. Busan Hills (A. Everett). The collection only contains four specimens of this species, but all in good preservation. It also occurred in the cave explorations made by Mr. Everett. 56. PUPINA EVANSI, n. sp. (Plate XXXIX. figs. 3, 3 a.) Shell globosely oval, polished, solid ; sculpture very minute, transverse, distant striation, probably more marked in the living state; colour quite faded, a slight tinge of brown remaining, so that it was probabiv of a bright polished brown; spire high, sides convex ; apex blunt ; suture very shallow ; whorls 5, sides convex ; aperture circular, perpendicular ; peristome thickened, discontinuous, not sinuate on margin, a very narrow slot at the columellar margin, another near suture.

Only two specimens were found by me iu the cave-earth ; it is quite distinct from the two other Pupinas discovered by Mr. Everett. |
