SUTER: NEW ZEALAND LAND MOLLUSCA, 37

— Note. —Laoma (PuRtxeNaTHus) AcCANTHINULOPsIS, Sut., which I 
described in Trans. New Zeal. Inst., vol. xxii (1891), is a synonym 
of Laoma (Phrixgnathus) phryna, Hutton. Since my description 
i published, well-preserved specimens of Z. phrynia have come 
into my possession, and, after careful comparison, | have come to 
the conclusion that my species is nothing more than a local variety. 
9. Laoma (Parixenarnus) Moriteyporrrt, n.sp. Pl. IV, Figs. 19-21. 
| Shell very small, depressly-turbinate, pale-horny with irregular 
radiate streaks of chestnut; faintly glossy, very thin, semi-transparent, 
‘smooth, microscopically decussate. Spire broadly conoidal, arched; 
periphery slightly keeled; whorls 4, gradually increasing in size, 
‘convex, the last not descending in front. Protoconch smooth, blunt. 
Aperture transverse, lunate; peristome straight, acute, outer lip some- 
what keeled, basal lp broadly arched, columella lip subvertical, 
‘slightly reflexed, and callous. Umbilicus narrow, deep, one-sixth of 
the major diameter. Base rounded. Diam. 2°5, alt. 1°65 mm. 
Type in my collection. 
Hab.—Mt. Wellington lava-fields, Auckland (H. 8.). 
_ This is another species closely allied to LZ. phrynia, but it is smaller, 
more depressed, is not ribbed, is microscopically decussate, and has 
a slightly narrower umbilicus. Named in honour of Dr. O. F. von 
Mollendorff, Manila. 
10. Laoma (Purixenatuus) Hamitroni, n.sp. Pl. IV, Figs. 22-24. 

















Shell minute, subdiscoidal, umbilicated, yellowish-horny, glossy, 
pellucid, smooth, with distinct lines of growth, impressed at the 
suture, not decussate. Spire flat, but little elevated; periphery 
rounded; whorls 33, slowly and regularly increasing, convex, the 
last not descending. Protoconch microscopically spirally striate. 
Aperture diagonal, rotundly lunate; peristome straight, acute, outer 
and basal lip regularly rounded, columella almost straight, oblique, 
much reflexed. Umbilicus about one-eighth of the diameter, deep. 
Base rounded. Diam. maj. 2°5, min. 2; alt. 1:25 mm. 
/ype in my collection. 
Hab.—Macquarie Island, where it was found by Mr. A. Hamilton, 
of Dunedin, in whose honour the species is named. 
_ The specimens were kindly given to me by Prof. J. T. Parker, 
of Dunedin. 
_ this species has its nearest allies, such as Zaoma occultus, Cox, etc., 
in Tasmania; and it is no doubt also very near to L. Campbellica, 
Hilhol, but I have not yet seen that species. 
11. Laoma (PHRIXGNATHUS) SUBLUCIDA, N.sp. 
q Shell small, depressly-turbinate, subperforate, whitish-horny, glossy, 
Semi-transparent, smooth, with faint, radiate, rufous streaks extending 
0 the umbilicus, not decussate. Whorls 5, gradually increasing, 
Hatly rounded; suture impressed; periphery rounded. Protoconch 
Smooth. Aperture transverse, lunate; peristome straight, acute, 
Slightly callous; outer and basal lip regularly arched, columella lip
