Euconulidae is a taxonomic family of minute, air-breathing land snails, terrestrial pulmonate gastropod mollusks or micromollusks. This land snail family is closely allied to the Zonitidae, the glass snails.

[edit] Distribution
Distribution of Euconulidae include Nearctic, western-Palearctic, eastern-Palearctic, Neotropical, Ethiopian, Malagasy, south-eastern Asia, Australian, Polynesian and Hawaii.[1]
[edit] Shell description
These minute snails have a shell which is roundly conical and broad-based, like the shape of an old-fashioned European woven bee hive or skep. For this reason these snails are sometimes known as "hive snails".
The shells of most Euconulidae are only about 3 mm in size, amber-colored and translucent.
[edit] Anatomy
In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).[2]
