Turbonilla (Babella) caelatior Dall & Bartsch, 1906
Synonyms
  • Chrysallida (Numaegilina) Nomura, 1938
  • Egilina (Numaegilina) Nomura, 1938
  • Numaegilina Nomura, 1938
  • Paregila Laseron, 1951

Description

The shell shows strong axial ribs between the sutures and three spiral keels, two of which are at the periphery, which falls in the deep sulcus between them, and one a little anterior to the middle of the base.[1]

Distribution

The genus seems to be limited to tropical and temperate regions of the Pacific Ocean.

Life habits

Little is known about the biology of the members of this genus. As is true of most members of the Pyramidellidae sensu lato, they are ectoparasites.
