Although Cox figured this form ho did not mention it in the text, and 
Pilsbry also figured a .S])eeimen whieh is here rofigured, and then Kohelt 
brought in a Brazier iMS. name tor this sliell. There are many specimens in 
the Australian Hiiseiim hearing Brazier’s M8. name, and localised as Doubtful 
Island, hut U’hicli Doubtful I. is intended must he found out by local collectors 
On the labels here it is said to be “Doubtful Island, King George’s Sound,’’ 
and many shells of the vi(do series are also so lalxdled, one set being the 
castaneus form (Pilsbry ’s fig. 18)., and another set agreeing with Pilsbry’s 
figure 3. It there he three distinct series of Both n'enihn/on living on Doubtful 
Island, the ])lace is in need of close investigation. The shell is a small thin 
representative of the kingii form, but is smaller, nari’ower and not so atten- ! 
uate as the tyi.dcal shell. It is always of a fawn colour, rarely streaked i, 
with reddish and the red circumbilical 2 >atch is usually absent. The apex i 
is elevated, normally i)unctate, th(> punctations linking u]) into lines, the 
adult scul]}ture easily separated, rough radial ribbing develo})ing below the 
suture Avhere it persists through growth. The radials become obsolete with ' 
age, while a regular series of concentric lines ai)i.H‘ars on the earlier whorls, 
none of which cuts the ra<!ials. The columella is apiJressed, almost closing 
the umbilicus, but generally a chink remains. The length of the figured 
specimen is 20 nun. with a breadth of 10 mm. 
Recent research suggests that this Doubtful Island is the island off 
Doubtful Island Bay, and this is confirmed by the name ma.ru'eJli as there 
is a Mt. iMaxwell overlooking that hay.

Specimens collected by E. Gratwick, 70 miles east of Israelite Bay, 
that is, some twenty miles east of the type locality of grahcicki. arc all 
dead, but show T'cmaiirs of the colour pattern, which is that of the liingii 
series. The shai)e is elegant, the body whorl not swollen, but the aperture 
about e()ual to the spire, the texture thin, the sjure is not acuminate. The 
coloration shows regular reddish flame streaks on a whitish ground, some 
however nearly unicolor. Apex elevated, ()unctat(‘, the succeeding seid)>- 
ture regular wavy growth lines rvith transverse cross lining but the rvholo 
seuli)tur(* very weak: the iiuckering below the suture is well marked and 
a little of the longitudinal radials remains on the body whorl. Golumella 
twisted and api^ressed so that no umbilical fissure remains, the shell 
appearing imperforate. A thin glaze crosses from the inner lip to the edge 
of the oiiter which is thin. Length of type 24 mm., breadth 12 mm. 
The locality is in the annual rainfall 15-20 inches belt.
