THE MOLLUSCA—HEDLEY. 443 
tapering to a slender point, the lower swollen to bulbous. Colour, 
which alters in drying, reddish purple to lilac, the apex and the 
lower row of gemmules usually cream. Whorls about eighteen. 
Gemmules subcircular, polished bosses, shelved above, separated 
by about half their own diameter, in two rows of about twenty- 
two ina whorl, alternating vertically ; the interspaces between 
the gemmules are spirally wrinkled. On the antipenultimate 
whorl a spiral thread arises between the two rows of gemmules, 
but following the sinuations of the upper, this gradually in- 
creases, becomes segmented, and on the last whorl forms an 
additional row of gemmules. Just behind the aperture extra 
rows are also intercalated. The protoconch is acicular, four or 
five whorled, the whorls bicarinate, crossed obliquely by numerous 
fine bars, which bead the carinz. The aperture is perpendicular, 
almost square, lip reflected, the right margin crossing the canal 
in a spur, the canal being closed by its anterior wall folded over, 
but not touching the pillar. Anal notch deep, a subcircular, 
subtubular, orifice in the place of the last sutural gemmule ; 
onwards from the last actual gemmule the lip is free from the 
body whorl. Length 74 mm. 
Common in shallow water in the lagoon of Funafuti. As the 
rare 7’. violacews has been generally confounded with the com- 
mon 7’. ruber, whose aperture is quite different, most literary 
records are untrustworthy, and I forbear to quote them. I have 
myself collected the species at Port Moresby and Milne Bay, British 
New Guinea, and at Oubatche and Noumea, New Caledonia. 
Specimens of 7’. ducosensis, Jousseaume, received from Noumea, 
from Mr. R. C. Rossiter, belong to the pale form of 7’. ruber. 
TRIFORIS CLIO, sp. nov. 
(Fig. 30). 
Shell rather small and slender. Oolour cinnamon-brown, lowest 
row of gemmules and extremity of canal white, other gemmules 
pale brown. Whorls fifteen. Protoconch five whorled ; first two 
together swollen and subglobose, shagreened, remainder bicarinate 
by a median furrow and crossed by numerous fine bars which 
bead the carine. The adult whorls are beset by first two, then 
three, and finally four spiral rows of gemmules, eighteen to a 
whorl, set vertically, gemmule above gemmule, up the spire. Broad 
furrows ascend vertically from whorl to whorl, deeper than the 
spiral interspaces which part row from row. The gemmules are 
lozenge shaped, polished, standing half their length apart and 
linked to their neighbours in a row by a coloured band smoother 
and shallower than the remainder of the vertical furrow, of which 
it forms a part. Between the gemmules the surface is roughened 
by close fine spiral hair lines. Two unbeaded cords run round 
the base. Aperture nearly vertical, outer lip bending round a
