- Original Description of Rostellaria powisii var abyssicola by Schepman, 1909, p. 154:
- ”Shell small, whitish, thinner than the eype, the upper whorls nearly smooth, with only one conspicuous groove, bordering a narrow spiral cord, just below the suture; this is continuous until the aperture, the upper part of last whorl, below that groove, smooth on the ventral side, angular on the place where in the type runs a third of the lirae, on the back with indistinct spirals, beginning with a row of punctures, more conspicuous behind the apertural margin, base of last whorl with conspicuous spiral cords, separated by punctured grooves; denticles and other particularities of the aperture, as in the type.
- Locus typicus: “Stat. 139. 0° 11’ S., 127° 25’ E. Moluca-Passage. 397 M. Mud, stones and coral.”
- Measurements: “Length of largest specimen 39 Mill. of smallest 33 Mill., it may have been in both specimen a little more, since the canal seems to be slightly broken.”

- Description of the radula of Rostellaria powisii by Schepman, 1909, p. 155:
- "The radula of a small specimen from Stat. 306 agrees in many respects with those of other Strombidae, it is short, with about 35 rows of teeth, its colour is yellowish. The rhachidian tooth ® has a body which is broad in front and suddenly narrower about halfway; its cusp has 11 denticles, of which the central one is the largest; the lateral tooth (1) has a transversely much elongated body and about 9 denticles on its reflected margin. The uncini (U) are long, slender, much curved, with a few small denticles on the sides. It was a male specimen with a long slender penis, ending in a thickened, spear-shaped point."
