346 LIEUT.-COL. H. H. GODWIN-AUSTEN ON [June 18, Operculum horny, multispiral, black-br >wn, with a pale centre, with a central minute hollow showing dark upon it, like the bull's eye of a target. Hab. Busan Hills (A. Everett). I place this species in the genus Jerdonia with doubt, the oper­culum of the S. Indian shell J. trochlea being of a decidedly cal­careous nature ; but unless the animal differs in other respects, it is not desirable to create a new genus only on the single character of the operculum. ALYCCEUS, Gray. Alycceus hochstetteri, Pfr. Alycceus hochstetteri, Pir. Malak. Blatt. vii. p. 215, pi. iii. fig. 14 (1860). 35. A L Y C C E U S S P I R A C E L L U M , Adams & Reeve. (Plate XXXVII. figs. 6, 6 a.) Cyclostoma spiracellum, Adams & Reeve, Zool. Voy. Samarang, Moil. p. 56, pi. xiv. fig. 1 (1860). This figure is not sufficiently good for the identification of the species, and I have therefore given an enlarged drawing taken from a typical specimen in the British Museum. 36. ALYCHEUS GALBANUS, n. sp. (Plate XXXVII. figs. 1, 1 a.) Shell dextral, pyramidal, closely umbilicated, the last whorl slightly constricted and swelling again towards the aperture ; sculpture very fine irregular transverse striation, a few stronger costulate strise near the sutural tube, smooth in front of this ; colour pale yellowish sap-green, dark on the apex ; spire high, conic; apex sharp ; suture moderately impressed ; sutural tube only 0*7 millim. in length, blunt; w horls 6, rather flat-sided; aperture circular; peristome double, the outer much expanded on the upper outer margin and forming a sharp nick on the columellar side ; columellar margin rounded. Size: maj. diam. 6*0 ; alt. axis 4*75 millim. Hab. Niah Hills (A. Everett). There are not many specimens of this pretty shell in the collection. 37. ALYCEUS GLOBOSUS, H. Adams. (Plate XXXVII. figs. 3, 3 a.) Alycceus globosus, H. Adams, P.Z. S. 1870, p. 794. Hab. Busan, near Sarawak. Shell dextral, globosely pyramidal, narrowly umbilicated ; sculp­ture very fine regular costulation, quite smooth from sutural tube to the aperture ; colour on apex pale orange, the rest very pale white with a slight green tinge ; spire conical, somewhat depressed ; apex blunt; suture well impressed ; the sutural tube short and club-like ; whorls 4, sides very convex, the last but very slightly constricted ; aperture circular ; peristome double, the outer lip much expanded on the columellar margin, covering the umbilicus. Size: maj. diam. 3*0; alt. axis 2*90 millim. Hab. Sarawak proper and Busan Hills.
