Conus omaria Hwass in Bruguière, 1792
Omaria cone, 81mm

Conus omaria is moderately common on lagoon interisland reefs and pinnacles. On many reefs, it is found under rocks in the daytime and emerges at night to feed on mollusks. But they seem most common in lagoon Halimeda patches, where they may be active during the day as well. It is similar to a number of other tented cones, but is most often confused with Conus episcopatus, from which it differs by its typically more cylindrical body shape and the shape of its spire. Usually, the widest part of Conus episcopatus is right up at the shoulder of the spire, while on C. omaria, it is a bit anterior of the spire. The pattern of the tents and brown markings also differ between the two species, but that takes developing an eye to discern the differences.

Here are a couple with their egg capsules.
