face wasin places so wet that he could brush off water with his hand. 
Professor von Haast reiterated his former statements, He said 
that the changes noted by Mr Grey had been produced by damp 
air blowing into the cave. Mr Gray could not analyse the outer 
layer spoken of by Professor Hutton, because it did not exist ; but 
Protessor von Haast allowed that in another cave a layer of stalag- 
mite overlaid the paint. The real question was, he said, whether it 
was the outer layer only that had scaled off, or pieces of the rock. 
Professor Hutton said that if that was the question he quite 
agreed with Professor Haast that the rock scaled with the stalag- 
mite. He never supposed that the scalings were only one-fiftieth of 
an inch in thickness. 
(4.) Descriptions of New Land Shells, by Professor F. W. 
Hutton. 
Patula tapirina, n. s. (P. coma, Trans. N.Z. Inst., XIV., p. 
150.)—More closely ribbed than P. coma, less closely than in P. 
infecta and P. buccinella; the right lip produced forward. Hab. 
Dunedin. : 
Microphysa pumila, n. s—Minute, sub-discoidal, widely umbili- 
cated, with distant membranous ribs; horny brown. Hab. North 
Canterbury (C. Chilton). 
Gerontia,n.g.—Like Patula, but theanimal with a mucous gland. 
Gerantia pantherina, n. s—Sub-discoidal, widely umbilicated, 
obliquely striated with membranous striz; horny brown. Diam. 
°37. Hab. Greymouth (R. Helms). 
Strobila leiodon, n. s— Minute, sub-discoidal, narrowly umbili- 
cated, closely ribbed; interior with seven body plaits, ten parietal 
plaits, and one columellar plait ; colour horny, banded with rufous. 
Hab. Greymouth (R. Helms). 
Amphidoxa cornea, n.s.— imperforate, striated, whorls 23, rounded; 
colour pale horny, without markings. Hab. Auckland (T. F. 
Cheeseman). 
Amphidoxa costulata, n.s.—Narrowly umbilicated; whorls 33, 
rounded, ciosely ribbed, and spirally striatulated; colour horny, 
banded with reddish. ab. Auckland (T. F. Cheeseman), 
Phriagnathus, n. g.—Shell conical, or turbinated, of 5 or 6 
whorls; jaw papillate, imbricately folded; teeth quadrate, bicus- 
pid; no caudal gland. 
P. marginatus, n. s.—Conical, umbilicated, carinated, striated, 
suture margined; colour horny, banded with reddish-fulvous. Hab. 
Greymouth (R. Helms.) 
Thalassia (?) propingua, n. s.—Narrowly umbilicated, convexly 
conoidal, carinated, the base rounded, strongly striated; colour 
pale horny, with numerous narrow zig-zag bands of red, often 
broken up into a series of spots. Hab. Weka Pass (C. Chilton). 
Less acutely keeled than 7. zealandie. The generic position of the 
species is doubtful. 
Zonttes helmsti,n.s.—Narrowly umbilicated, with thin rather dis- 
tant ribs, whorls broader than high; colour horny brown, some- 
times variegated with rufous fuscous. ab. Greymouth (R. Helms.) 
Zonites fulminata, n.s.—Narrowly umbilicated, striated, columel- 
lar lip callous, reflected over the umbilicus; colour horny, with 
zig-zag red bands. Hab. Stewart Island (T. Kirk.) Near H. venu-
