Terebra anilis
Terebra anilis is a species of sea snail, a marine gastropod mollusc in the family Terebridae, the auger snails. Description
The length of the shell varies between 15 mm and 111 mm. (Original description) The narrowly subulate shell is reddish brown. It contains 21 very flat whorls. These are sculptured with oblique, rather closely set transverse costae interrupted by spiral striae and two crenate sutural bands, the upper of which is much the broader. The sutures are scarcely impressed. The columella descendis in a curve, extending into a thick, projecting callus which joins the lip above. The peristome is sinuous and slightly reflexed. The aperture is narrowly ovate. The siphonal canal is short and recurved
