Entemnotrochus rumphii, common name the Rumphius' slit shell, is a species of large sea snail with gills and an operculum, a marine gastropod mollusk in the family Pleurotomariidae, the slit snails.[2]
This marine species occurs off Japan, Taiwan and the Philippines.[3]
The width of this large gastropod shell is 130–285 mm.[3] The shell has a broadly conoid shape with a convex base. It is moderately umbilicated, the umbilicus penetrating to the apex. It is a little plicated within by the prominent growth lines. The color is yellowish-white, with flames of orange or carmine red, and light violet, particularly developed on the body whorl. The apex is eroded and yellow. The number of whorls is uncertain, probably between 11 and 13. The whorls are visibly convex and divided into nearly equal portions by the slit fasciole, which is a little above the middle. The sculpture is composed of oblique, radiating striae, more prominent on the upper whorls. The base of the shell is almost smooth, with a slight stride of growth and very fine concentric lines. The nacreous aperture is obliquely quadrangular. The basal margin is continuous with the columella, and is not angulated at its junction with it.[4]

Entemnotrochus rumphii (Schepman, 1879) é uma espécie de molusco gastrópode marinho da família Pleurotomariidae, sendo a maior espécie dentro de sua família,[2] podendo atingir tamanho acima de 25 centímetros.[3]
Entemnotrochus rumphii, juntamente com a outra espécie conhecida do seu gênero, Entemnotrochus adansonianus (Crosse & P. Fischer, 1861), do Caribe, são dotados de concha cônica, pesada e sólida, possuindo as fendas laterais, típicas de Pleurotomariidae, mais longas do que as dos membros de outros gêneros.[3] E. rumphii apresenta concha de coloração creme a amarelada com difusos desenhos, de cima a abaixo, em tons de laranja e vermelho.[4] Possuem o umbílico aprofundado.[5]
São encontradas em águas profundas do oceano Pacífico (Indonésia,[6] Filipinas, Taiwan e Japão).[5]

龙宫翁戎螺（学名：Entemnotrochus rumphii），俗稱為龍宮貝，是原始腹足目翁戎螺科翁戎螺属的一种。分布于日本、台湾、印尼沿岸，常栖息在深海。[1]
龍宮翁戒螺是非常古老的生物，出現於古生代寒武紀，距今約五億七千萬年至四億九千萬年前; 繁盛於中生代，而由新生代開始漸趨絕跡。在1968年開始陸續有漁船在東沙群島、釣魚台列嶼、台灣海峽撈獲活體，故可稱之為「活化石」。
