Oenus GLOBOEHAGADA Iredale 
1933 — Glohorliagada Tredale, Kec. Ausir. Mus., A’ol. XIX, p. 52, Aug. 2. 
Orthoty|ie Helix (llddra) priulhoannix Smith. 
1 distinguished this form as a subgeuus of Rhagada, observing that the 
type species was globo.se, with open circulai' mouth, the columella thickened, 
uuich reflected and appressed. but not closing tbe umbilicus, a thick glaze 
Joining the inner and outer lips. 
The globose form separates this group clearly and the apertural charac- 
ters appear distinct troni those of true Ehagada. I'he colinnella crosses the 
umbilical cavity whereas the llJi/ignda specii's have it entering it.

“Shell uinbilicate, globose (whitish, clothed with a yellowish epidermis); 
whorls five convex, rapidly increasing, striate with (.blique growth lines, the 
last whorl large, iuHated, obliipudy descending smldeuly at the aperture; 
spire obtusely conoidal ; aperinre rotunda tely-lunate, length about three-fifths 
of the height of the shell; peristome intei'iorly slightly thickened, outwardly 
scarcely expanded, a little effuse anteriorly, a thin callus Joining the margins, 
columeila obli(|ue, rellected, dilated above, almost hiding the umbilicus. Diam. 
mag. 25, min. 20 mm.; alt. 22 mm. Aperture 1-1 long, 11.5 broad. Ilab. as 
above. 
This is a smooth globular species, probably rvithout much coloration, 
judging from the only t wo s]»ecimens at hand. These are in a dead condition, 
without any trace of colour, and jirolmbly arc move or less bleached. The 
umbilicus is deep and moderately broad; the inner edge of the oblique 
columella is gently arcuatiq bid the outer margin is almost .straight or faintly 
incurved.”

Specimens from Broome agree fairly save that they are slightly larger, 
and topotypieal examples are not available.
