Remarks
Trigonostoma obliquata had been caught from Wakayama and southward to
tropical Ocean. However, this shell was found also in Mouth of Tokyo Bay
recently. Cancellariidae live in tropical waters in the world, and this
family contains a lot of interesting shape shells .
Trigonostoma pellucida of the Philippines and Trigonostoma milleri
of Galapagos have especially strange shape.
