Type species of Microfulgur Finlay & Marwick, 1937
Classification: Turbinellidae: Vasinae?
Description: Small for family (height 15-25 mm), pyriform, spire low, conical. Protoconch of 2 whorls, described as "conoid-papillate". Teleoconch whorls strongly clasping, reaching up to periphery of previous whorl; sutural ramp steep, slightly concave. Last whorl with rounded periphery, strongly excavated below to form long, curved neck. Axial sculpture of growth lines only; spiral sculpture of narrow, sharp cords which are much stronger on periphery than above or below. Aperture pyriform, columella gently convex with weak fold at top of the long, open siphonal canal. Inner lip moderately thickly callused over columella, thinly in parietal region. Outer lip thin, with weak sinus on ramp, gently convex and subvertical below.
Comparison: Microfulgur longirostris is superficially similar to Fyfea lirata but is somewhat larger and more elongate, and has a much longer siphonal canal. Microfulgur is known definitely only by the type species but Ponder (1970) described a Recent species, Microfulgur(?) carinatus , from 730 m off the Otago coast. Its generic assignment is very doubtful. Also, Tudiclana birdi Stilwell & Zinsmeister (1992, p. 140, pl. 19i, j) from Eocene rocks of Seymour Island, Antarctic Peninsula, appears to be a species of Microfulgur.
Distribution: Wangaloan, Wangaloa Formation, Wangaloa (type); Boulder Hill (uncommon at both localities).
