Ovulatibuccinum perlatum – Fraussen & Chino, 2009: 152, 154, figs. 7–8, 17–18. — Hasegawa 2009: 289, fig. 183.

Etymology

Named in honour of Mr Mitsuo Chino, citizen scientist in malacology, who co-authored the description of Ovulatibuccinum perlatum .

Type material

Holotype JAPAN • lv (SL 8.4 mm); northeastern Honshu , off Iwate Prefecture; depth 900–1000 m; NSMT-Mo 76771 .

Distribution

Known from the slope of the Japan Trench (type locality), off northeastern Honshu (350–480 m; Hasegawa 2009) and Kurile-Kamchatka Trench. Bathymetric range: the lower continental plateau from 300 m down to abyssal depth of at least 2700 m. Inhabiting muddy and silty bottoms (after Fraussen & Chino, 2009).

Remarks

After synonimization of Ovulatibuccinum with Buccinum the new combination Buccinum perlatum ( Fraussen & Chino, 2009) is becoming the junior secondary homonym of Buccinum perlatum Conrad, 1833 and Buccinum perlatum Küster, 1858 (= Engina natalensis Melvill, 1895 ). Since there is no known available and potentially valid synonym, according to art. 60.3 of ICZN the name Buccinum perlatum must be replaced by a new substitute name proposed herein.
