* List of countries might not be complete


Shell moderately large, elongate-ovate, yellowish white. Nuclear whorls decollated. The postnuclear whorls are well rounded and bear a moderately strong angulation at the anterior termination of the posterior sinal area. The last postnuclear whorl bears 14 broad heavy axial ribs which are not quite as wide as the spaces that separate them. The preceding turn has 11 ribs. The spiral sculpture consists of 6 slender spiral threads in the sinal area, while at the angulation a heavier cord is present which renders the axial ribs nodulose. The space between the angulation and the suture bears 5 low spiral cords between which finer spiral threads are present. The base is moderately long, well rounded, and marked by the continuation of the axial ribs and 15 spiral threads, between which and on which finer spiral striations are present. The columella is moderately long and marked by feeble spiral threads. Aperture pearshaped. The posterior sinus extends from the summit to the angulation and is shallow. Anterior to the posterior sinus the outer lip is protracted. The inner lip is reflected over the columella as a smooth area which extends over the parietal wall. The type, U. S. N. M. No. 274112, was dredged by the U. S. Bureau of Fisheries steamer Albatross at station 4538 in 871 fms. on gray sand and rock bottom, off Point Pinos Light. It has 4 whorls remaining and measures: Height, 13.3 mm.; greater diameter, 6.2 mm. NOT FIGURED.

Interchangeable taxa

This species is much larger than Propebela (Turritoma) diomedea, with the axial ribs coarser, heavier and even more distantly spaced, while the nodulation of the shoulders of the whorls is much less strong.
