Original Description of Struthiolaria mirabilis by Smith, 1875 , p. 67:
- "Testa ovata, tenuis, imperforata, leviter turrita, alba, epidermide tenuissima fugaci olivaceo-alba amicta ; anfractus 6 1/2, convexiusculi, superne anguste planulati, lente accrescentes, longitudinaliter oblique arcuatimque crebre plicati (plicis inferne ad suturam vix attingentibus); liris spiralibus prominentibus supra plicas undulatis (in anfr. superioribus 7-8, in ultimo circiter 22, illis infra medium simplicibus) succincti; apertura longitudinis totius circiter 4/7 aequans; columella arcuata. Operculum corneum unguiculatum, inferne costis duabus a nucleo unguiformi divergentibus munitum, superne medio longitudinaliter unisulcatum, concentrice striatum. Long. 42 mill., diam. 22."
Locus typicus: Swains Bay, Kerguelen Islands, Territory of the French Southern and Antarctic Lands, southern Indian Ocean
Comment Smith, 1875, p. 67:
- "But a single specimen of this very remarkable shell was obtained by Mr. Eaton. This unfortunately has the labrum so much broken away, that it is impossible to describe the form of the aperture and the nature of the basal channel. However, the animal and operculum agree in all respects externally with Struthiolaria; and although the shell has more the general aspect of Buccinum, there can be no doubt of its true location. The species which compose this genus are strong thick shells; this, on the contrary, is particularly fragile, and clothed with a very thin deciduous epidermis."
