licus deep ; aperture roundly lunate; peristome thin, acute, margins 
nearly approximating, columellar margin not reflected.

Hab. Knocklofty; also the Old Mill, Hobart Town, Tasmania, 
under logs (Coll. Brazier). 
This species comes near to H. tasmanie, Cox, from Mount Wel- 
lington—a rare shell to obtain; whereas H. neglecta is a very 
common species in the localities I have given. 
6. Hretrx (CHAROPA) AMMONITOIDES, 0. s. 
Shell umbilicated, flatly discoid, not shining, finely and promi- 
nently irregularly ribbed, the interstices with very fine striz, white 
beneath a thin brownish epidermis; spire flat, suture slightly im- 
pressed; whorls 34, very regularly increasing, last rounded above 
and below, base convex, with striz the same as on upper surface ; 
umbilicus large, with the bottom flat, not very deep; aperture ob- 
lique, roundly lunate ; peristome simple, the thin epidermis covering 
it, margins approximating. 
Diam. maj. 0°11, min. 0°10, alt. 0°5 une. 
Hab. Mount Nelson, Tasmania, under stones in moist places 
(Coll. Brazier). 
This little species has the appearance of an Ammonite in form ; 
but it must not be confounded with Helix ammonitoides of Reeve, 
which is only a synonym of Helix omicron, Pfr. 
7. Heirx (?CHaARoPA) DISPAR, 0. 8. 
Shell umbilicated, depressedly convex, arcuately, coarsely, and 
sharply ribbed, interstices with very fine radiating striz, bright, 
horny; spire conoidly obtuse, suture depressed; whorls 5 to 53, 
convex, last rounded, not descending, base convex, with radiating 
striee descending into the deep umbilicus ; interior of the aperture 
with a little oblong white prominent callous tooth nearly on the 
base ; aperture vertical, semilunar ; peristome simple, acute, margins 
joined by a thin callus (in some specimens prominent), basal 
margin not reflected. 
Diam. maj. 0°13, min. 0°11, alt. 0°11 une. 
Hab. Mount Wellington, Tasmania, under leaves (Coll. Brazier). 
This species is the only one I know of in Tasmania with the small 
tooth in the interior of the aperture. We have H. biscutata, said 
to come from the same locality, but none so small as the present 
little species, which is somewhat like a small species that I have 
from Norfolk Island. 
8. Heirx (HYALINA) NELSONENSIS, 0. s. 
Shell umbilicated, depressed, very thin, shining, pellucid, obliquely 
and finely striated; spire slightly elevated, obtuse; whorls 34, last 
increasing, convex, slightly depressed above at the mouth, base 
convex, faintly marked with indistinct strize of a reddish horn-colour ; 
umbilicus moderately large; aperture nearly diagonal, slightly
