). Formula ∞+3+1+3+∞, with ±50 transverse rows of teeth. Rachidian with lateral flanges of shaft slightly expanded creating a relatively weak hood; central cusp well developed, lanceolate and with two smaller lateral cusps on each side. Lateral teeth overlapping extensively, their cusps asymmetrically trigonal; central denticle largest, lateral denticles well developed on outer margin, progressively decreasing in size toward tooth shaft; inner margin with fewer denticles. Marginal teeth numerous and slender; cusps of inner ones recurved, narrowly and asymmetrically spathulate, inner margin straight and smooth, outer margin curved and finely pectinate for a considerable distance; outer marginals similar, but with pectinate outer margin extending further down shaft; outermost marginals somewhat broader.

There can be little doubt, however, that the material from Walters Shoal belongs to the same species. It is evidently associated with seamounts in the vicinity of the Southwest Indian Ridge and appears to be a species with southern rather than tropical affinity.
