One kind of the conch that イトグルマ (a spinning car, a scientific name: Columbarium pagoda pagoda) is classified in new stomach foot eyes オニコブシ department イトグルマ subfamily. It is from the Choshi - Sea of Japan central part and to the south and is distributed over the fine sand bottom of depth of the water 20-300m of the East China Sea.

Form

Husk high 5-8cm, a spinning car type about husk 3cm in width. The husk color of the brown, husk list when is shiny, is various when there is not it. A water pipe groove occupies about 2/3 of higher husk very for a long time, and there is a small splinter line a lot. In addition, a clear angle is at the husk bottom; on the corner with the splinter line of the 1~3 book (is generally considered to be one line as for one line of chart type). This splinter row is one of the important characteristics to distinguish it from an approximate kind, but is often vague.
