District (liicluinl Helms). 
The Western shell has been associated with pacificus by Smith, and 
Pilsbry, although the latter noted the discontinuous distribution, and tigured 
as representative of a Xortli Queensland island shell, siieeimens from 
Narrabri, inland New South Wales, Forrest River, West Australia, and ap- 
parently only one from Fating- Island, almost in the south of Queensland. 
The last named, as would naturally be concluded, appears to be the nearest 
to Ihe true paci/ica. The Forrest River shell is here named. Shell small, 
pupoid, dextral, whorls convex, sutures deeply impressed, umbilicate, apex 
obtuse, coloration pale brown, outer lip white. The apical whorls are smooth, 
the adult whorls obli(iuely lincdy striated with threads, in some cases well 
marked, the mouth rather small. Length 4.25 mm.: breadth 2 mm.

Mr. W. W. Froggatt collected a few specimens of a puiiioid shelli in the 
Rarrier-Napier Range, and these break u[' the “pacifica’’ pihantasy. 
They are detlnitely of that association, but also perfectly distinct, being 
smaller than any of the so-called forms, measuring 3.5 mm. length by 1.5 mm. 
in breadth. The whorls are Hatter than in the previous sprecies though the 
.sutures are deep, the shell darker coloured, the sculpitnre weaker, the mouth 
comparatively larger, the shell having; a more squat aiijiearance. 
This is apjiarently the lirst inland represeulali\e in Australia of the 
‘‘pacified” series.

Aprparently there is deflnite loc.-d variation in this species as -well as 
individual variation, and a good series from Cardanumbi .shows all the spreci- 
mens to be broader than cotypes of Itelliana. The.se may be regarded as a 
subspiecies T. h. contexta nov. The tyj'c measuring 0 mm. in length by 
2.75 mm. in breadth, .some even being broader, whereas the typje of belliana 
was only 4.5 mm. in length by scarcely 2 mm. in breadth, piaratypes lieing 
more slender still. A series from Nangeenan via Alerredin collected by Air. 
E, Sedgwick, shows a more conical form than any of Pilsbry’.s excellent 
lig'ures, recalling a de.xtral lig. 9 (contra da). The .shells are variable in size 
but all .show the same shape, the whorls flatly rounded, the sutures deep), the 
angular nodule rathei- small, and may be called T. b. asserta, snbsp. nov., the 
type measuring 5.5 mm. in hniglh and 2.5 mm. in breadth. 
FAAIILY PUPILLIDAE. 
The usage of northern families for southern shells will pirobably later 
be as amusing to onr sneccssors as son;e of our predecessors’ wmrk is to our- 
selves. Nevertheless it is necessary to have some refuge' for these wails, and 
therefore the above is here used w-ith reservation.
