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.
