170 DR. J. C. COX ON NEW AUSTRALIAN SHELLS. [Mar. 24, 
3. Descriptions of eight new Species of Shells from Australia 
and the Solomon Islands. By Jamgs C. Cox, M.D., 
C.M.Z.S. 
(Plate XVI.) 
1. Hexrx RAInBrIRDI, Cox. (Plate XVI. fig. 1.) 
Shell deeply openly umbilicated, globosely turbinate, rather thin, 
faintly striated, dark chestnut-brown, almost black, ornamented by 
two broad dark yellow bands about the centre of the whorls, and one 
round the umbilicus, which is much excavated and broadly funnel- 
shaped ; spire broadly conoid, obtuse ; whorls 63 to 7, convex, last 
deflected in front; aperture oblique, roundly lunate; lip dark and 
metallic at the margin, broadly expanded and somewhat reflected ; 
margins approximating, joined by a thin callus; columellar margin 
much expanded, overhanging the broad, open, funnel-shaped umbi- 
licus. 
Hab. Mount Dryander, Port Denison, Queensland. 
Diameter—greatest 1°75, least 1°20; height 1°35 inch. 
This fine species, named after its discoverer, was sent to me as 
Helix mitchelle, Cox, which in general appearance it much re- 
sembles ; it is, however, easily distinguished by its less conical shape, 
and by its being openly umbilicated, whereas H. mitchelle has a 
covered umbilicus. 
2. Hexurx THATCHER], Cox. (Plate XVI. fig. 2.) 
Shell deeply and openly umbilicated, depressedly globose, rather 
solid, finely obliquely striated, dull horny yellow, ornamented with a 
broad, dark chestnut band below the suture, with five or six fine 
dark lines round the centre of the whorls, and also a dark undefined 
zone round the umbilicus, which is of the same colour; this dark 
coloration extends across the last whorl in a broad undefined band 
along the margin of the aperture, and joins the band beneath the 
suture; spire flatly conoid ; whorls 63, flattened, the last becoming 
much inflated, rapidly enlarged and a little depressed in front ; base 
flat; aperture oblong-oval, large, oblique, livid white within; lip 
slightly thickened and everted, of a lighter colour than the interior ; 
margins approaching, joined by a thin dark callus ; columellar margin 
much dilated, half concealing the umbilicus. 
Hab. Mount Bersaker, Rockhampton, Queensland (Raindird). 
Diameter—greatest 1°60, least 1°20; height 1°15 inch. 
An interesting species, of an intermediate form between Helix ap- 
pendiculata and H. incei, but easily distinguished from either by the 
marked inflation of the last whorl. 
3. Hewrx nov#-GEorGIENSIS, Cox. (Plate XVI. fig. 3.) 
Shell imperforate, globosely depressed, surface corrugated and 
shiny, white, ornamented with 5 or 6 narrow brown bands; apex 
of spire bluntly rounded; whorls 4, rapidly increasing in size, each
