Material.— A fragment, broken at both ends, of a presumably adult, straight free anterior tube portion ( MSNC 4531 ) originating from “Pietra di Salomone” Limestone, the Sosio Valley , western Sicily ( Italy); Wordian to upper Permian .

Description. —The sole collected specimen is 9.5 mm long and 2.9 mm in cross section and appears entirely recrystallized. It consists of a tube fragment corresponding to an anterior tube portion. It is rather massive and solid, circular in cross-section with a constant diameter of 2.9 mm. Lumen 2.4 mm wide. Tube wall thick (0.3 mm). Outer surface smooth, except for densely situated thin but distinct circular growth lines, equally spaced. Some more marked growth lines may be interpreted as weak annular peristomes, although there is no obvious difference between growth lines and peristomes. Posterior encrusting tube portion unknown. Large secondary calcite crystals occur in the tube wall, whose original structure is totally biased by diagenetic recrystallization.

Remarks.—The specimen exhibits unequivocal serpulid characters, which are otherwise too poor for specific and generic assignment.
