ABSTRACT
Thirty-three Recent calliostomatids are recorded from New
Zealand, ten of which are described as new Calliostoma (Otu-
haia) blacki (Dell, 1956) is renamed due to homonymy, and
the following taxa are newly synonymized: Venustas tigris
chat liamensis Dell, 1950 with Calliostoma (Maurea) tigris
(Gmelin, 1791); Maurea punctulata ampla Powell, 1939 and
V. punctulata multigemmata Powell, 1952 with C. granti
(Powell, 1931); V. cuuperi Vella, 1954 and Thoristclla chath-
amensis profunda Dell, 1956 with C. blacki (Powell, 1950),
which is resurrected from synonymy under C. joveauxanum
(Dell, 1950); Zizijphinus hodgci Hutton, 1875, Z. ponderosus
Hutton, 1885, and C carnicolor Preston, f907 with C. sctectum
(Dillwyn, 1817); C. undulatum Finlay, 1923 and C. pellucidum
spiratum Oliver, 1926 with C. pellucidum (Valenciennes, 1846).
Lectotypes are designated for Trochus selectus Dillwyn, 1817,
T. pellucidus Valenciennes, 1846, and Calliostoma onustum
Odhner, 1924.
Key words: Mollusca; prosobranch gastropods, Trochoidea;
Calliostomatidae; Calliostoma, systematics.
INTRODUCTION
The family Calliostomatidae comprises about 250 living
species. They occur in all oceans from the intertidal zone
to about 3000 meters depth, mostly on rocky ground. All
known species are carnivores, most feeding on cnidaria,
and sometimes carion, though a few feed exclusively on
sponges. The group is particidarK well represented in
the New Zealand region, with 33 living endemic species,
including some of the worlds largest, notably Callios-
toma (Maurea) tigris (Gmelin, 1791), which may e.xceed
100mm in shell height.
Besides the 33 Recent species recorded herein, at least
double this number are known from the New Zealand
Cenozoic (Early Eocene
