Pisania fasciculata is a species of sea snail, a marine gastropod mollusc in the family Pisaniidae, first described in 1846 by Lovell Augustus Reeve as Buccinum fasciculatum.
Description The length of the shell of the lectotype attains 28.4 mm its diameter 10.4 mm.
(Original description) in Latin of Pisania crenilabrum) The shell is fusiform (spindle-shaped) with a prominently protruding spire. It is brown in color, adorned with a broad band that is obscurely jointed with chestnut-brown markings. There are seven whorls in total; the uppermost whorls are folded lengthwise, while the final, largest whorl is transversely ridged. The aperture is oval and relatively short. The inner lip is covered by a glossy callus, while the outer lip is somewhat thickened on the outside, featuring a finely notched margin. Adams, A. (1855). Descriptions of thirty-nine new species of shells, from the collection of Hugh Cuming, Esq. Proceedings of the Zoological Society of London. (1854) 22: 130-138, pl. 28
The species is variable in colour, being either brown, reddish-brown, grey or purplish, and is occasionally ornamented with axial streaks and small white spots on the spiral striae; in some specimens the dark axial zones and white spots are absent.
Distribution This species occurs in the Indian Ocean off the Mascarene Basin; also off New Caledonia.
