Biology Type of larval development: short planktonic, non-planktotrophic [details]
Diagnosis Shell 12-15 mm long, with oval-elongate contour and moderately elevated profile, apex very close to posterior margin, definitely coiled. Sculpture of numerous radial ribs, high and ragged, crossed bu comarginal cordlets which form tubercles on tht top of the ribs. Slit broad and rectangular, extending over 1/5 of the distance to apex. Colour yellowish white. [details]
Distribution Eastern Atlantic, from Bay of Biscay to Morocco; rare in the Western Mediterranean and the Adriatic Sea (generally on rather deep rocky bottoms, ca. 80-200 m)
Gorringe and Ampère seamounts (moderately common in 70-480 m); Josephine and Seine seamounts (rare in 165-385 m). [details]
Taxonomy There is considerable confusion in the taxonomy of this species group and the treatment here follows Bogi & Giusti (1994). The similar species E. multistriata Jeffreys, 1882 (= guernei Dautzenberg & Fischer, 1896) has a similar sculpture but grows larger (up to 20 mm), with a broader contour and a higher profile. Emarginula tuberculosa Libassi, 1859, which also lives in the same environment, is distinguished by the distinctly coiled apex overhangin the posterior margin. [details]
