Shell small, dextral, umbilicately fissured, oblong, thin, shining, smooth, white ; whorls 5, rounded, the last small, suture impressed, narrow ; apex obtuse j aperture somewhat squarely ovate, longer than broad, denticulated with 5 teeth, 4 prominent, the upper one large, placed in the centre of the aperture, and extending upwards in a thick rounded callus, the second placed to the left, minute and rounded, the third on the columella, thick and pointed, the fourth facing the upper, moderately pointed, the fifth about equal in size to the fourth ; the aperture divided into four parts, peristome thickened and expanded, smooth and white, margins joined by R thick callus continuous with the peristome and extending over the body-whorl.

4. PUPA (VERTIGO) SCOTTI. Shell dextral, fissured, cylindrical, thin, transparent, pale browii ;

whorls 5+, roundly cnnvex, last small, obliquely and trausversely faintly striated ; apex roundly obtuse ; aperture small, ovate, denti- culated within with 4 prominent white teeth, one placed on the bodj- whorl, elongated and rounded, a second on the columella large and acute, two placed inside the outer lip, the lower one long and pro- minent, the upper moderate and rounded ; peristome whitish, thick- ened and expanded; margins continuous, with a thin coating of callus over the perforation.

Length 3, breadth 4 lin. Hub. Fitzroy Island, north-east coast of Australia; only one

specimen obtained, at the watering-place, under a bit of wood (coll. Brazier).

I have named this after the Rev. W. Scott, Astronomer, Sydney.

whorls 4+, increasing rapidly, last large, flattened, spirally keeled, with one above and one below the periphery, the space between them having a hollow appearance ; umbilicus large, with a keel sur- rounding it ; aperture oblique, circular ; peristome simple, thin, acute. Operculum horny yellow, thin, concave, multispiral.

lin. Diam. maj. 1, min. 8 , alt. Hub. Fitzroy Island, north-east coast of Austrslia ; found under

wood, near a freshwater stream (coll. Brazier). This interesting species belongs to the new subgenus Ditropis of

l{lanford ; it reminds one of a miniature Tropidophora cuvieriana or T. tricarinata, with its prominent keels.

I have named it after Mr. White, F.R.A.S., Astronotner, of Mel- bourne, Victoria.

*6. DIPLOMMATINA GOWLLANDI. (Plate LXXXIII. figs. 19-21.) Shell dextral, rimate, acuminately oblong, white, hyaline, finely

and obliquely ribbed, interstices smooth ; spire conical, apex acute, sometimes decollated ; whorls from 6 to 7, sometimes 9, the first three forming the apex are regular and tapering, the fourth broad, the fifth longer and broader, the sixth very small, having a pinched or distorted appearance in front, the seventh or last extends nearly up to the suture of the sixth ; aperture vertical, subcircular ; peri- etome thin and broad ; margins continuous, shining, the outer broadly expanded, the columellar margin thick, straight, slightly channelled in front, tooth within minnte.

Diam. maj, 18, min. 8, alt. 6 lin. Hub. Fitzroy Island, north-east coast of Australia ; found at the

root of a large tree, crawling upon the grass (coll. Brazier). This curious species differs from any of the Diplommatina! that I

have met with, the first three whorls forming the apex being regular aiid tapering, the fourth a little broader, the fifth still longer and broader, the sixth having a pinched-in appearance, while the last is large, giving the shell a most distorted aspect ; the greatest breadth is at the fifth whorl, the least a t the sixth. The few hundreds that I collected are all of the same description. I have named it after my late lamented friend John Thomas Ewing Gowlland, Staff-Com- mander H.N,, who was unfortunately drowned while surveying in Port Jackson, August 1874, and who was in charge of the steamer that conveyed the Eclipse Expedition to Cape Sidmouth.

*7. GEORISSA MULTILIRATA.

Shell imperforate, globosely conical, reddish brown, strongly spi- rally striated, interstices rather rough, shining ; whorls 4, roundly convex, suture channelled j spire conical, apex papillary, base convex, very finely marked with spiral lines ; aperture vertical, lunate ; peri- stome thickened ; columellar margin straight, thickened, with a white callus around the perforation, which is hollowed out. Operculum shelly, ovate, smooth, brownish, with a long pointed shelly protu- berance on the underside or place of attachment to the animal.
