Scaberrimum

Scaberrimum is a genus of small, terrestrial snails, terrestrial pulmonate gastropod mollusks in the family Strophocheilidae. The genus was first described by the French malacologist Jean-Baptiste de Lamarck in 1822. The name "Scaberrimum" is derived from the Latin words "scaber," meaning rough, and "errimus," meaning most, referring to the rough, irregular shell surface.

The genus Scaberrimum is characterized by its small, conical to cylindrical shells with a rough, irregular surface. The shells are typically brown or gray in color, with a distinct spiral sculpture. The genus is found in the eastern United States, with species ranging from New York to Florida.

The genus Scaberrimum includes several species, the most well-known of which is Scaberrimum americanum. This species has a distinctive, rough shell surface and is commonly found in moist, shaded habitats such as forests and swamps.

The taxonomy of the genus Scaberrimum is still a subject of ongoing research, with some species being reclassified or redescribed based on new morphological and genetic data. Despite this, the genus remains an important group of small, terrestrial snails with a unique and distinctive shell morphology.
