Popis

Natal hunter snail
A relatively large species with the apex of the spire characteristically tapering, giving the shell a distinctive biconical shape; surface not obviously glossy, some specimens more or less smooth, others sculptured with indistinct, close-set axial riblets; suture line often rather more coarsely milled or puckered; apertural dentition typically 5-fold (though very variable), but all teeth relatively weak: 1) a parietal lamella; 2) a mid-labral tooth; 3) a tooth inside basal lip, to left of centre; 4) another on columella lip; 5) a low, deep-set columella shelf; some individuals with an extra weaker tooth above labral tooth; there may also be a slight bump to the right of the basal tooth. Length up to 11 mm. Head-foot greenish-yellow to green, neck and tentacles darker.
Endemic to the Zululand-Transkei region, from Dukuduku Forest (St Lucia) south to Dwesa Nature Reserve in southern Transkei; primarily coastal, but recorded inland to Botha's Hill and the Kranskop area; little habitat data available, but the localities suggest it is to be found in dune, coastal lowland and scarp forests, and riverine woodland; occasionally found alive in leaf-litter during dry periods, but evidently largely arboreal. Has been collected on the undersides of the lower leaves of large trees such as the stink ebony (Heywoodia lucens). Few specimens have been found in recent years and the species may now be rare; undoubtedly it has suffered from dramatic reduction in its habitat. Compare with C. pondoensis
