Paleontology

Range —Miocene of Quilon, Kerala, India.
Remarks—This species appears from the de-scription and figures to be a Comitas rather than a Turricula. It is Fusinus-like, with rather sparse heavy axial folds, 6-8 per whorl, subobsolete over the shoulder slope but strong medially, and overridden by primary cords and secondary threads.
Description—(original) — Shell of medium size, fusiform; spire elevated, its height equal to that of the aperture and canal combined; protoconch small, smooth, blunt, probably consisting of 2 whorls; subsequent whorls 9, compressed at the suture, increasing rapidly in size, ornamented with both axial ribs and spiral lines; the axials are strongly swollen and conspicuous at the periphery, but absent on the wide area in front of the suture; they number 8 on the body-whorl; overriding them are primary and secondary spiral threads, the number of which increases with the growth of the shell; on the penultimate whorl there are about 5 primary threads; suture bordered by a narrow and delicately crenulate spiral cord, in front of which is a wide concave area bearing indistinct spiral lines and strong growth-lines, concave towards the aperture; aperture lenticular; anterior canal long, slightly oblique; parietal wall callused; outer lip broken away."
