Conus yanuyanuensis
(Ladd, 1945)
No additional material collected. I have not been able to find a described species, fossil or living, having the unique combination of characters shown by the single Fijian fossil. It is a slende'r form with a high and slightly convex spire whose whorls have a well-developed shoulder keel ; the body whorl is smooth except for weak spirals anteriorly. A feature not mentioned in the original description is the presence of beads on the peripheral keel of early whorls.
Measurements of the holotype, now USNM 175130: length
19.0 mm, diameter 7.4 mm, height of spire 5.2 mm.
Occurrence.-A single specimen from station 110C, Vanua
