Jujubinus tumidulus (Aradas, 1846)
Canale di Sicilia.
Grazer and deposit feeder, at least in the upper circalittoral. Original taxon: Trochus tumidulus.
 
The shell of this species is stocky, the diameter expanding quickly in the early whorls, and more slowly in the last ones. This shape, « subovato-conica » according to Aradas, recalls that of montagui but the shell is smaller, paler, and the sculpture is very peculiar: the spiral cords are deeply incised by the prosocline furrows, more deeply than in any other mediterranean Jujubinus. The colour is uniform, sandy to yellowish, sometimes very pale.

Above: 50m deep, Hurds Bank, Sicily Channel. 3mm.
