Rhynchozoon lobulatum: Gautier, 1962: 242 . Rhynchozoon pseudodigitatum Zabala and Malu
quer, 1988: 147.
DESCRIPTION (AMNH 1004): A single, small, encrusting, multiserial, unilaminar colony. Primary orifice wider than long, the anter denticulate and the poster shallowly concave between small, rounded condyles. Within the peristome is a broad, straightedged uncinate process, the free corner of which is produced and may abut against opposing side of peristome wall, defining a pseudospiramen. Lateral suboral avicularium, with hooked rostrum acute to plane of orifice and laterally directed; soon obscured by a thickened peristome, with a lobed rim developing into knobbed processes projecting over the lumen. Frontal shield nodular, vitreous, with some nodules developed as pronounced knobs. Small adventitious avicularia with slender, triangular rostrum, distributed sporadically on frontal shields of autozooids, with variable orientation.
REMARKS: The shape of the primary orifice and the lobed peristome rim are typical of R. pseudodigitatum as described and figured by Zabala and Maluquer (1988), who considered that the single specimen from the Gulf of Marseille attributed to the poorly defined R. lobulatum Waters by Gautier (1962) was the same species.
OCCURRENCE: The single, small colony which appears to be attributable to this species was encrusting shell.
DISTRIBUTION: Mediterranean; this current record represents the first occurrence of the species in the eastern Mediterranean.
