« Shell rather cylindrical, thick, opaque, lustreless. Sculpture: numerous straight longitudinal striae, which are crossed by fewer and finer spiral thread-like striae, so as to present a reticulated appearance and to make the points of intersection tuberous or scabrou ; the spiral striae are 4 on the last whorl, besides a basal line below the periphery, and 3 on each of the preceding whorls; the second, and sometimes also the third whorl is marked with close-set and curved longitudinal striae; the first whorl is quite smooth and glossy. » – J. G. Jeffreys: “n the Mollusca procured during the ‘Lightning’ and ‘Porcupine’ expeditions, 1868-70 (Part IX)”, Proceedings of the Zoological Society of London, year 1885, p.95.

Protoconch: first whorl adorned with thin orthocline radials crossed by 3 very weak spiral keels; on the second whorl, the radials become flexuous and opisthocline; at the transition, these radials revert to orthocline. – Base: the two cords that encircle the base distinguish Krachia from the other genera.
