Species / Anchura Hoggi

Original description of Anchura ? hoggi by Stephenson, 1941, p. 303:

  • "This species is based on two specimens, one adult and the other about half grown, both of which are incomplete at each end. Shell thick and of medium size with spiral angle of about 35 degrees. Whorls closely appressed, suture sharply but slightly impressed. Sides of whorls broadly rounded; on the whorls of the spire the greatest convexity is a little below the midheight. The body whorl is moderately plump and very broadly rounded on the periphery; the base slopes gently to the anterior canal. Axials numerous and gracefully sinuous on the body whorl where they number 23; they are round-crested, only moderately prominent, and die out well down toward the base. Spirals numerous, rather obscure, overriding the axials; they are more distinct on the base of the body whorl than elsewhere. Aperture lenticular with a narrow anal canal at the rear, and passing into a well defined siphonal canal in front, only the upper end of which is preserved in each specimen. Outer lip broken away. Inner lip broadly excavated, forming a thick callus above just below the anal canal, becoming only thinly covered with callus on the lower part of the parietal wall. Columella smooth, slightly twisted."
