Fuegotrophon Powell 1951

“Subgenus Fuegotrophon n.subg.

Type : Fusus crispus Gould, 1849

This new subgenus is provided for a small group of Magellan Trophons of fusiform shape with turreted spire and long canal, and sculptured with spiral cords crossed by bluntly rounded axials and a dense surface covering of low crisp lamellate ridges. Its distinctive features are a paucispiral, asym­metrical, rather bulbous, smooth protoconch and a dentition that departs somewhat from the stereotyped monotony of most Trophonoid radulae. These differences are exhibited in the central tooth, which has the massive central cusp reinforced by a buttress which extends below the lower margin of the basal plate. The basal plate is broad, shallow and rectangular, but with three basal projections caused by a downward extension of the outer basal extremities, plus the base of the central buttress. The upper and outer extremities of this plate are upwardly produced to form two extra cusps, giving a formula of seven cusps instead of the usual five. The three primary cusps are well developed with the central one largest; the intermediates are very little less in size than the outer primary cusps and of approximately equal size to the extra cusps on the outer extremities of the basal plate. The transverse ridge representing the upper edge of the central tooth bears groups of several parallel vertical grooves, or incipient denticles, at each outer extremity.

The operculum is ovate-quadrate with a blunt terminal nucleus situated at the lower right-hand corner.”
