but sometimes may be 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 as 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 univalve 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 Lotorium 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 
Putara. 
SIPHONALIA DILATATA (Plate IV.).—Fig. 1 has a pale 
yellow or greenish interior, the outside being reddish brown. Com- 
mon 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 24} 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
