I am informed bv Mr. Edgar Smith that although the British Museum purchased all the types in Mr. Henry Adams's collection, this shell was not among them, and that the type is probably lost. 38. ALYCEUS HOSEI, n. sp. (Plate XXXVII. fig. 2.) Shell dextral, tubinately pyramidal, narrowly umbilicated ; sculpture very fine close regular costulation, slightly better defined at the sutural tube, quite smooth thence to the aperture; colour very pale with a slight tint of sea-green ; spire high ; apex pointed; suture well impressed, the sutural tube fine and short ; whorls 5|, sides convex, the last with a slight contraction in front of the sutural tube; aperture circular; peristome sharply edged, the outer lip being much expanded and rising on the last whole but one and contracting again on the inner margin ; columellar margin circular. Size: maj. diam. 5*75; alt. axis 6*25 millim. Hab. Busan Hills (A. Everett). 39. ALYCEUS EVERETTI, n. sp. (Plate XXXVII. figs. 5, 5 a.) Shell dextral, not depressedly tubinate, widely umbilicated ; sculpture quite smooth above, close costulation at sutural tube, gradually decreasing to a few distant very minute striae, fine close costulation within the umbilicus; colour whitish, apex pinkish brown; spire suhconic ; apex papillate; suture deep, the sutural tube 1*5 millim. in length, well developed ; whorls 4, sides convex, the last slightly constricted near sutural tube, then swelling and descending towards the aperture; aperture oblique ovate, angulate above at inner upper margin of the peristome ; peristome double, the outer expanded slightly and to its greatest extent on lower inner margin ; columellar margin rounded. Size : maj. diam. 5*0 ; alt. axis 2*5 millim. Hab. Niah Hills (A. Everett). Only one specimen of this species was found. 40. ALYCCEUS SPECUS, n. sp. (Plate XXXVII. figs. 4, 4 a.) Shell dextral, globosely conical, narrowly umbilicated ; sculpture fine rather distant ribbing, stronger at sutural tube and more distant anterior to it; colour bleached ; spire conic ; sides flat; apex blunt; suture impressed, the sutural tube moderately long, stout; whorls 4, rounded ; aperture circular, angulate above near suture; peristome double, outer expanded ; columellar margin rounded. Size: maj. diam. 3*25; alt. axis 1'75 millim. Hab. In limestone caves at Jambusan (A. Everett). I found four examples of this small species when looking over the cave-earth .'-ent home by Mr. Everett; it has not yet been found livine, but is doubtless abundant in suitable localities. |
