Terrestrial Gastropods of the Columbia Basin, British Columbia

Family EUCONULIDAE H.B. Baker, 1928 Genus Euconulus Reinhardt, 1883 Euconulus fulvus (Müller, 1774): Brown Hive Synonym. Conulus fulvus alaskensis Pilsbry, 1899. Description: Shell small (width, 3.2 mm), subconic-heliciform, width only a little greater than height; surface with a silky, shining texture; translucent brown; spire moderately elevated; apex obtuse; whorls slightly convex and numbering 5.5; periphery rounded or a little angular; suture deep; protoconch smooth; teleoconch with fine, close axial striae and exceedingly fine spiral striae; axial striae obsolete and spiral striae more apparent on the base; aperture narrowly crescent-shaped and without denticles; outer lip unthickened; umbilicus closed or almost so. The body is greyish with darker tentacles and the mantle has large, black blotches. The foot is very long and slender (Pilsbry 1946). Similar Species: Compare also with similarly shaped species of Pristiloma, which have shells with proportionally lower spires and different sculpture. Habitat: Common and widespread, living under logs and debris in dead grass and leaf litter in a variety of habitats, both dry and moist areas at all elevations. Reported up to 3,048 m [10,000 ft] in Montana (Vanatta 1914). Range: Holarctic. Throughout Europe, Asia, North Africa, North America, in the Azores (Backhuys 1975) and Madeira (Cameron & Cooke 1996). In North America it was recorded throughout most of the U.S. by Hubricht (1985) and known as far south as northern Mexico (Bequaert & Miller 1973; Naranjo-García 1991). Distribution: Throughout British Columbia, and one of the most generally spread species. Notes: The form E. fulvus alaskensis was said to differ from typical fulvus by having one less whorl in shells of similar size, and by minor sculptural differences (Pilsbry 1910, 1946), but Henderson (1936) and Berry (1937) expressed difficulties with the distinctiveness of alaskensis. Branson et al. (1966) doubted whether this form merits recognition, and Bequaert & Miller (1973) stated it not possible to segregate alaskensis consistently using shell characters. Name: Genus name in reference to the cone-shaped shell. Species name meaning "tawny" or "reddish yellow".
