AGE AND LOCATION OF TYPE MATERIAL . — Tlecerina - Glanta assemblage, Middle Devonian, Kurosegawa tectonic zone, southwest Japan . TAXON CODE. — 016. STATUS. — Valid. ORIGINAL DIAGNOSIS. — “ Ceratoikiscidae with bilaterally symmetric shell. Central skeletal frame triangular with five to six extratriangular rods. Shell perforate or imperforate, covering a.t . and the dorsal portion of i.t ., supported by many trabeculae arising from a.t . and the dorsal portion of i.t . Aperture of the shell facing to the ventral portion of b.t . Single pair of free-developed caveal ribs originating from a-/b- junction, projecting almost perpendicularly to the central skeletal plane.”( Wakamatsu et al. 1990: 180 ). REMARKS Umeda (1998) emends the diagnosis to indicate that the lamellar shell is always perforate.
