Attiliosa


Attiliosa is a genus of sea snails, marine gastropod mollusks in the subfamily Aspellinae of the family Muricidae, the murex snails or rock snails.

Characteristics

The genus currently contains about 33 recognized species, with several fossil species dating back to the Eocene. The genus was established by William K. Emerson in 1968. In older malacological literature, many Attiliosa species were originally described under the genera Murex, Muricidea or Vasum
The genus is often characterized by sturdy, fusiform shells with prominent axial ribs and spines.
The shape of the shell is generally ovate-fusiform to short-fusiform, with an acute, pyramidal spire. Most species are relatively small, ranging from 15 mm to 30 mm in length. The sculpture consists of 7 to 9 varices per whorl. These varices often bear short, sharp, or tubular spines. The aperture is usually oval and often reinforced with lirae on the outer lip. Many species are white, waxy or light tan, sometimes decorated with brown spiral lines or spots
