Gemmula kieneri: Shell attaining 5 cm, aperture 0,45-0,48 total length, sutures narrowly channelled; subsutural cord weaker than shoulder cord, with 3-4 lirae; peripheral cord moderately projecting with 23-31 shallowly bifid gemmae, their intervals with 2 very weak spiral threads; shoulder sulcus evenly concave, subequal to subsutural cord in width; basal periphery of body whorl with 4 main cords; all main spiral ridges granulose, growth striae coarse. Whitish with subsutural cord and intervals between both gemmae and granules orange-brown. Protoconch diameter 1,5 mm. Radula as in G. cosmoi.
Description: Shell with 9-10 teleoconch whorls, aperture slightly shorter than spire (0,45-0,48 total length); spire more or less orthoconic, sutures narrowly channelled. Subsutural cord moderately strong, bearing 3-4 crenulate spiral ridges, the lower or penultimate one the strongest, the ridge bordering the suture being very thin and rather cristate. Peripheral cord markedly stronger than subsutural one, but not forming a prominent shoulder angle; gemmae prosocline, with shallowly bifid, angular crests, 23-31 on penultimate whorl, becoming weak and imbricately lunulate just behind labrum; intervals with 2 feeble spiral threads. Shoulder sulcus evenly concave, subequal in width to subsutural cord, bearing 3-4 thin, rather high spiral lirae, rendered crenulate by growth threads. Body whorl with 4 main cords at periphery of base, separated by groups of 1-4 fine intermediary threads; 1 main cord visible on spire whorls; basal lirae becoming progressively finer on rostrum, alternately more or less weaker and stronger, crossed by thread-like growth lines. All main spiral ridges distinctly granulose. Ground colour white to yellowish-white, intervals between gemmae and between granules on basal cords dark orange-yellow to deep yellowish-brown, subsutural region blotched with the same colour. Protoconch of about 4 pale yellowish whorls; axial riblets commence on penultimate whorl, where opisthocline; on last whorl thin, arcuate, prosocline and about 19 in number; maximum diameter 1,5 mm.Radula: Rachidian transversely rectangular with very prominent mesocone. Dimensions: 48,8 x 16,7 mm; 45,3 x 15,7 mm; 40,6 x 14,1 mm.
