Bostryx turritus is a species of tropical air-breathing land snail, a pulmonate gastropod mollusk in the family Bulimulidae.

Distribution

This species was known from Trujillo Province in La Libertad Region (Pilsbry, 1896)[3] and Pariacoto in Ancash Region (Haas, 1955).[2][4] Recently, Ramírez (2004)[5] reported it from Cerro Pasamayo and Salinas de Huacho in Lima Region.[2] She also refers to unpublished data by Weyrauch, who collected the species at Cerro Campana, 14 km north of Trujillo 07°58’54’S 079°06’24’W (selected as type locality by Ramírez) and near Chilete in Cajamarca Region.[2] Breure (1978)[6] reported the species from the same department near Magdalena.[2] Breure (2010)[2] reported it from Catzcal 1050 m, 09°54’43’S 077°49’40’W, Ancash Region, Peru.[2]

Zilch (1953)[7] reports Bostryx turritus turritus (shell height/shell width = 3.25) from Hacienda El Casa Grande (probably near 07°40’S 078°40’W) in La Libertad Region, and described Bostryx turritus tamboensis (shell height/shell width = 2.87) from the same locality, albeit from different elevations (1500 m resp. 1000 m).[2] According to Haas (1955)[4] – reporting a locality at 1360 m – his shells ‘are slightly more slender than the typical form’.[2] The specimens from Catzcal show a variation in ration shell height/shell width from 2.84 to 3.18 (mean 3.00; n = 7).[2] It is possible that this variation can also be found in the populations at the localities in La Libertad, in which case Bostryx turritus tamboensis should be considered a synonym of the nominate taxon.[2]

Description

Living animal are whitish-grey throughout, the black eye-retractors are shining through the tentacles and the dorsal side of the body.[2]
