Shell very .small, siil;coiiical, whorls a little rounded, sutures lightly im- 
pressed, last whorl deseeiidiiig rather' rairidly, mouth sirbeireirlar, oblique, 
outer lip thin, eolumella rather' broadly relleeted, obscirr'ing- a little the narrow 
open do('p umbilierrs. Color'atioir pale browrrish. Aprex very finely eon- 
ceritrieally striate, aborrt two whorls, adult whor'ls thr'ee arrd a half, sculpture 
with fine growth striae and thr'srr ar'e crossed by ver'y obscure eorreentrie 
striatrou. A ferv distant large atr'iae develop but they carr scar-ccly be called 
ridges: these rrurrrber about lwenty-tr\-e to llrir'ty birt they are irregular'ly 
spaced and never- pr'omirierrt. Breadth 1 rrrrrr. : height .8 mm. 
Found ali\’e under' karr'i bark in dense wattle ser-ub. 
FAMILY DIPNELICIDAE. 
This family was introduced for arr irrteresting' shell from Hammock 
Island, South Austr-alia, and it was r-emarked “It has not yet been discovered 
on the mainland, which srrggests that it is a I’elict form of great age.” Mr. 
Sidney W. -laeksorr collected, at the Bow Kiver arrd Deep River, specimens of 
another cur-rorrs shell, arrd though it ditfer's in detail it seems to recall the 
South Australian shell rrr sortre respects. It apparerrtly does not fit into any 
of the other families, such as Char'opidae, Lamnidae, Flanrmulinidae or 
Rhytididae. 
Germs ANNOSELIX gen. nov. 
Tyjre A. dolosa-sp. nov. 
Plate I., lig.s. 24 and 27. 
A very curious little shell, i-egrrlarly broadly conical, the base convex, the 
pori|)hery keeled, umbilicus deep, very rnirrow, the mouth squarish, the outer 
lip thirr, columella. 
Coloration brown, base paler browrr, but sometimes flamed with reddish 
brown. 
One apical whor] apparently smooth but obscurely radially str-iate, the 
str'iae developing on the adult whorls Avithorrt any' intervening varix. Thera 
are four and one-half adult whorls regularly increasing, whorls flattened, 
sutures scarcely inurressed. The r-adial striae develop slowly and become very 
numerous and fine, while a delicate concentric striation also forms, j)rodueing 
a very fine semi-cancellate appearance. On the ba.se the concentric spirals 
generally predominate. Breadth, 7., 5 mm. ; height 5 mm. 
The type is from Deej) River, and some specimens from Bow River. 
South Coast, show that, in some cases, the radials, every now and then, 
strengthen into ridges and create a fringe at the periphery and continue 
strongly on to the base. This fringe sticks out a little, and presents a saw- 
like appearance to the peripheral keel. 
FAMILY CHAROPIDAE. 
This family has a few members in Y'estc-rn Australia, but there may' be 
many' more, as they are minute and difficult to find. Seven species have been 
described and while one is rejected, a few are added. One eastern genus, 
Femarjera, based however on a western shell, i.s admitted, Init the remainder 
of the species ajipear to be of endemic origin. All the species so far seen 
have no armature of the mouth, and all are openly- umbilicate. The features 
of the family are the small size of the shell, the depressed helicoid form, com- 
monly- discoidal, with an adult sculpture of numerous radial ridges of varying 
strength.
