Fusiform, white species. Protoconch flattened and keeled. About five convex elongated teleoconch whorls. Spiral sculpture of relatively thickened, sometimes slightly unequal, chords. There are about four spirals on each whorl. Axial sculpture of fine lamellae, which do not reticulate the surface. Aperture oval about half height, with a rather large sinus and moderately long, slightly oblique siphonal canal. Size: 10mm. The animal is transparent yellowish in colour, eyes large black at middle of tentacle stems. Operculum thin, transparent yellow and corneous. The species lays its eggs singly, attached to tubes of polychaete worms on muddy substrates. Eggs with different stages of development were found only millimetres apart on one tube. The young have a direct development.

Remarks. Drilliola emendata has a sculpture basically similar to that of D. loprestiana, but it is more slender and has an obtuse, carinated, whitish protoconch. The protoconch of loprestiana is pointed and composed of three brownish whorls with bent axial ribs. D. emendata has direct or lecithotrophic larval development.
We have tried to check P. renieri and P. crispata, to be sure that the new name emendata introduced by Monterosato for the species described by Philippi and for the Recent Mediterranean species was not an unnecessary addition to the list of names. The types of Scacchi (of whom there are a few types in MNHN) and De Cristofori & Jan (Pinna, 1971: 424) are lost. Both species were described as tertiary fossils and knowing the great similarity between even unrelated species of Turridae, we have preferred to use the name of Monterosato, and to stabilize it by selection of a lectotype from material sent to Locard by the author.

Distribution. The bathyal zone of the Mediterranean; apparently restricted in the Atlantic to the continental slopes of Iberia and N.W. Africa. The shallowest record is 45 m in Corsica (Gianinni, 1975: 90).
