Remarks . The species is very rare, represented until present by only the holotype . It evolved probably from the genus Patulibracchium Pessagno , its probable forerunner, by the reduction of the arms probably during the Cretaceous-Tertiary boundary crisis. Judging from the morphology of the holotype , it seems that it is a young specimen with the arms incompletely developed. This holotype differs from T. centrospina Dumitrică especially by the angle between the lateral primary rays that reaches 160°, rather close to that of some Campanian species of the genus Patulibracchium illustrated by Pessagno (1971) . Range and occurrence . Earliest Paleocene, DSDP 21- 208-31 CC , Lord Howe Rise, SW Pacific.
