M a t e r i a l. Three incomplete dorsal valves (figured PCZCU 2277, PCZCU 2278) and one small complete shell preserved as external moulds (PCZCU 2288).

D e s c r i p t i o n. The shell is small, ventri-biconvex, subcircular, 5 mm wide, with carinate ventral and sulcate dorsal valve, and with a moderately thick wall. The dorsal valve has 13 to 15 rounded undivided ribs slightly curved laterally. Microornamentation consists of fine growth fila.

R e m a r k s. The shell is similar to fragments referred to Carinatina arimaspus which is present in the UDI but differs in its finer ribbing.

O c c u r r e n c e. UDI, sample TM 10, TM 12.
