/plʊˈrɑdəˌmɔɪd/

Origin: A borrowing from Latin, combined with an English element. Etymons: Latin Pleurotoma , -oid suffix.

Etymology: < scientific Latin Pleurotoma (see pleurotomid n.) + -oid suffix. With use as adjective compare slightly later pleurotomine adj. With use as noun compare slightly later pleurotomid n. N.E.D. (1907) indicates the stress as pleuˈrotomoid.

Zoology. rare (disused).

A. adj.

Resembling or allied to the genus Turris (formerly Pleurotoma) of gastropod molluscs having a spindle-shaped shell with a tall spire and a slit running up from the outer lip.

ΚΠ

1881 Amer. Naturalist 15 718 The name Candelabrum (used by him in 1878 for a Pleurotomoid genus having the posterior surface of the whorls concave, and with the keel produced backward in spines like those ornamenting the varices of Murex), appears to have been used by Blainville for a radiate.

1902 Amer. Naturalist 36 929 Thus we may have every gradation from the long slender spire of certain pleurotomoid shells to the perfectly flattened or even slightly sunken spire of certain species of Conus.

B. n.

A gastropod mollusc of the genus Turris or family Turridae. rare.Apparently only attested in dictionaries or glossaries.

ΚΠ

1890 Cent. Dict. Pleurotomoid, a shell of the family Pleurotomidæ.

1907 N.E.D. at Pleurotomid Pleurotomoid, a mollusc of this family [sc. the Pleurotomidae].
