MOLLUSCA FROM ALPINE ZONE OF MOUNT KOSCIUSKO — HEDLEY. 103 
lines are evanescent. The penultimate whorl has 61 coste. The 
first whorl is spirally grooved. Aperture oblique, lunate ovate, 
lip deeply incurved at the suture, rising above the vertex, arched 
above and below, not thickened and scarcely reflected at the 
columella. Inner lip overlaid by an opaque granular callus 
burying in its advance the costai in its path. 
Diameters, major 3^, minor 2f, height 1| m.m. 
Log. — Wilson’s V alley, at an altitude of 4,500 ft., Mt. Kosciusko, 
N.S.W. (Helms).

This species nearly approaches E. antialba , Beddome, from 
Tasmania, from which its narrow umbilicus and shallow spire 
readily distinguish it. Other species compared by their respective 
authors to E. antialba are E. subantialba , S liter, from New 
Zealand, and E. a mnia , Tate, from Central Australia ; besides 
other differences both are much smaller than that now introduced. 
Tlammulina excelsior, n . sp. 
(Plate XXIII., Figs. 2, 3, and 4). 
Shell large for the group (subgenus Flammulina ), turbinate, spire 
rather elevated, thin, translucent, surface dull, barely perforate, 
whorls three, rapidly increasing, last flattened above, rounded at the 
periphery and ventricose on the base. Suture impressed, coloured 
on a pale ground by angular brown flamesof irregular pattern, usually 
most distinct at the suture and fading away both at the periphery 
and on the penultimate whorl, frequently directed downwards 
and forwards they cross the growth lines diagonally and breaking 
up about the periphery produce a mottled pattern. Sculpture, 
close irregular growth lines commence as coarse wrinkles at the 
suture and fade into the smooth base, faint spiral scratches are 
seen under the microscope to cross these ; the earliest whorl 
exhibits regularly spaced costae crossed by fine spiral stria}. 
Aperture oblique, ovate, lip sharp, the somewhat twisted 
columella is folded over a minute perforation ; a thin granulated 
callus is spread over the inner lip and curves around the umbilical 
region. Diameters, major 9, minor 8, height 6 m.m.

This very fragile shell of a group hitherto unrecorded from 
Australia seems in shape to be nearest allied to F. cornea , Hutton, 
from Auckland, New Zealand, from which its size, colour, and 
perforation distinguish it. In a bottle with Cystopelta , but without 
locality more precise than “ Victoria,” Prof. W. Baldwin Spencer
