Striatobalanus ? sp.

( Fig. 4 )

Distribution: Late Pliocene to early Pleistocene (Piacenzian - Gelasian); Taiwan, (this record).

Material Examined: Taiwan. CIMFO0059- 0062: from an actively eroding escarpment at Chaiyi Niupu - 23°25'40.8"N, 120°33'25.7"E

Description: Shell smooth, high-conic, with six solid compartments, radii solid, narrow with smooth, rounded sutural edges, summits steeply dipping; paries strongly interlocked with a solid, calcareous base ( Fig. 4 ); opercula unknown. Exterior with alternating dark and light transverse banding.

Remarks: A lack of opercula prevents an accurate taxonomic placement for this material. Striatobalanus is represented in the modern Taiwan fauna by four species - S. amaryllis , S. krugeri , S. taiwanenis and S. tenuis - all of which possess very pale shells ( Chan et al. 2009).
