but sometimes may he found crawling amongst rocks. It has no operculum. The Australian specimens are more handsome than the New Zealand ones. The Maori name is Pupuwaitai.
LOTORIUM RUBICUNDUM.—The lower figure, until lately known as the Triton nodiferus, from the old legend that it was the shell on which Triton blew at the bidding of Neptune to calm or rouse the waves, is a heavy, solid shell, varying a great deal in shape and colour; but usually brownish pink, variegated with dark brown. No difficulty will be found in identifying it. The specimens from Australia have more pink and less brown, and are not quite us fine as those of New Zealand. It is found on rocks and grassy banks in the North Island, but from being sluggish in its habits the point of the spire in large shells is usually worm-eaten, and good specimens over six inches long are seldom seen. The Lotorium tritonis, the largest wnivalve in the world, is similar to the Lotorium rubicundum, but not quite as solid or heavy. It has occasionally been found in the Northern part of New Zealand. The Maoris used it as a trumpet, fastening a mouth-piece to the spire. The Polynesian specimens of the Lotorinum tritonis attain a length of nearly three feet, but nine or ten inches is the extreme length of our specimens. The Maori name is Pupukakara, or Putera.
SIPHONALIA DILATATA (Plate IV.).—Fig. 1 has a pale yellow or greenish interior, the outside being reddish brown. Common on sandy, exposed beaches, and is sometimes over five inches long. The Maori name is Onare roa.
SIPHONALIA MANDARINA (Plate IV.).—Fig. 2 grows to the same length as the Dilatata; but is a narrower and more graceful shell. The interior is usually greenish. Found in the same localities as the Siphonalia dilatata.
SIPHONALIA NODOSA (Plate IV.),—Fig. 3 is a pretty shell, sometimes 2½ inches long. The interior is whitish, and the exterior the same colour, with purple and white markings. It is common on ocean beaches and sand banks in harbours.
STRUTHIOLARIA PAPULOSA (Plate IV.).—Fig. 4 is a handsome yellowish shell, with brown or purplish stripes. The interior is purple. The nodules on the whorls are very prominent. This shell is sometimes four inches long, and the lip, when the shell has attained full size, is remarkably strong and solid, forming a
