Description
The fusiform shell is solid and wrinkled. The uppermost whorls are concave, slightly striated and largest near the middle of the keel. Below, it shows small alternating keels. The suture is simple. The outer lip wraps slightly inwards.It is chiefly distinguishable from it in the absence of any keel between the principal keel and the suture, and in some minor characters. The epidermis is covered with pale brown. [https://www.biodiversitylibrary.org/bibliography/15774 - The Annals and magazine of natural history; zoology, botany, and geology; v.13=no.81-86 (1844)]
This is a very considerably larger shell than Polystira oxytropis, but in the character of the sculpture they closely approach each other.
Distribution
This marine species occurs in the Mexican part of the North Pacific Ocean.
