Perrinia angulifera is a species of sea snail, a marine gastropod mollusc in the family Chilodontaidae.[2][3][4]
The size of the shell varies between 5 mm and 26 mm. The imperforate shell has an elevated-conoidal shape. The nearly plane whorls are imbricated and angulated below. They are longitudinally nodose-costate, and ornamented with transverse girdles of subdistant tubercles. The interstices are channelled. The body whorl is subangulate. The columella is straight and short. It terminates in a small tooth. The outer lip is subduplicate and sulcate inside.[5]
