It is most nearly allied to H. australis, Chemn. 10 t. 166. f. 1604, but differs from it in being rounder and more distinctly ribbed.
104. Haliotis cunninghamii (n.s.)
Testa ovato-rotundata tenuis depressa rugoso-subplicata spiraliter striata intus argenteo et rubro margaritacea, spira prominula, foraminibus parvis. Icon. —
Shell roundish-ovate, thin, depressed; the outer surface very slightly concentrically plaited and rough, and finely, regularly, spirally, striated; the row of perforations slightly elevated, pierced with eight or nine small slightly-tubular holes; the spire rather prominent, apex placed about one-fourth of the breadth of the shell from the sutural angle on the outer lip, consisting of four whorls which rapidly enlarge; the inside expanded out, disk nearly flat exhibiting one distinct whorl; the columella lip narrow, rather long, flattened; the outer lip thin, truncated; the nick of the imperfect perforation placed about one-third the length of the outer lip from the end of the columella lip: length six inches, breadth five.
This shell, at the wish of Captain King, has been named after Mr. Allan Cunningham, the botanical collector of the voyage.
This species, although nearly allied to Haliotis midae, is quite distinct from it.
105. Haliotis squamosa (n.s.)
Testa ovato-oblonga convexa rugoso-plicata aurantio-rubens spiraliter costata, costis tuberculato-muncatis, fauce margaritacea, spira retusa. Icon.
Shell ovate-oblong, convex, externally transversely rugose, plaited and spirally ribbed; the ribs concentrically striated and furnished with numerous raised scale-like tubercles; the row of perforations scarcely round contains ten or twelve rather large holes; the spire slightly raised, very near the edge, consisting of two or three very rapidly-enlarging whorls; the inside concave, showing the external ribs, reddish pearly; the columella lip narrow, depressed, bent; the outer lip thin, strait, or cut out; the imperfect perforation about one-fifth the length of the outer lip from the end of the columella lip; length two, breadth one inch and a quarter.
This species is very distinct on account of its long form, and curved lower face, as well as its outer surface.

This specimen, which is the largest I ever saw, measures three inches and a half by two and a half. It was found upon Rottnest Island, on the West Coast.
