not given). Menke described scabricosta from Mistaken Island, 
in King George Sound. The right side of reoi is straighter than 
the rounded left margin, and the back depressed; spiral riblets 
numerous, unequal, separated by deeply cut grooves, their sum¬ 
mits cut by fine radiating striae, and further rendered uneven 
by more or less developed folds radiating from the suture; spire 
rather elevated; columellar plate narrow, obliquely truncated 
at base; inside silvery, very iridescent, with pink, green and steel 
blue reflections; columellar plate narrow, obliquely truncated at 
its base; perforations a little raised, numerous. The orbicular 
form, and knotted spiral cords separated by deep grooves are 
characteristic; the columella is rather narrower than usual.

Lamarck 1843: = H. cunnin ghami Grav: = //. granti Pritchard 
5c Gatliff 1902). “The Conical-tubed Haliotis.” Very large, 
rounded-oval, flattened and disc-shaped; distance of protoconch 
from margin about one-fourth the length of shell. Length 175, 
breadth 135, height 35 mm. Not uncommon, on rocks just be¬ 
yond low tide mark, from Glenelg River to Yorke Peninsula. 
Not recorded from Western Australia. Recorded from Victoria. 
(Type locality—Kangaroo Island, South Australia). The out¬ 
line is rounder than H. naevosa Martyn, and flatter; right side 
less curved than the left; the tube-like perforations stand upon 
a strong keel which sometimes makes the dorsum appear con¬ 
cave; colour dull red, with obliquely radiating revolving flames 
of whitish-yellow on the earlier part of the body whorl; it may 
be reddish-brown, variegated with green and darker brown; 
finely spirally striated near the apex, but later this sculpture gives 
place to coarse wrinkles of growth; there are also low radiating 
waves or folds in places; spire is not much elevated; inside is 
light, veiy iridescent, red and silver predominating; columellar 
ledge or plate flat, broad; cavity of spire large, verv broad, shal¬ 
low; open holes variable in number, from seven in young speci¬ 
mens to lour in senile individuals. Verco considers it open to 
question whether this is not really a variant of H. naevosa Mar¬ 
ty 11 ? as although many examples can be easily distributed in their 
typical species, others cannot be so readily named. 
H. scalaris Leach 1814. PI. 1 , fig. 5. (= II. tricostalis La- 
marck 1822: not II. rubicund us Montfort, which is not an Aus¬ 
tralian Shell). Rounded-oval, depressed; reddish or variegated 
olive and green; with a strong spiral rib on each side of the row 
oi holes, and prominent elevated radiating lamellae around the 
spue; open holes, five to six. Length 75, breadth 53 mm. In
