Orthalicidae
Orthalicidae (orthalicid land snails) are a family of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks are classified in the subfamily Orthalicoidea of the order Stylommatophora. They are medium-sized to large snails, from about 3 cm (about 1.2 inches) to 9 cm (about 3.5 inches) in shell length

Taxonomy 
In former times, this family was often known as the Bulimulidae, but this term may also denote what today is the subfamily Bulimulinae. The subfamily Bulimulinae replaces the former family Bulimulidae Crosse & P. Fischer, 1873. 2005 taxonomy 
The Orthalicidae belong to the Orthalicoidea, a superfamily in the order Sigmurethra. Like other stylommatophorans, the Sigmurethra belong to the suborder Helicina. Among the three subfamilies of Orthalicidae, the Bulimulinae are the most diverse, consisting of three tribes:

subfamily Amphibuliminae P. Fischer, 1873 - synonym Peltellinae Gray, 1855 (check decision of International Commission on Zoological Nomenclature for Peltellinae) - 17 species
subfamily Bulimulinae Tryon, 1867 - 1243 species
 tribe Bulimulini Tryon, 1867 - synonyms: Bulimidae Guilding, 1828 (inv. ); Berendtiinae P. Fischer & Crosse, 1872; Bothiembryontidae Iredale, 1937
 tribe Odontostomini Pilsbry & Vanatta, 1898 - 125 species
 tribe Simpulopsini Schileyko, 1999 - synonym: Tomogeridae Jousseaume, 1877
subfamily Orthalicinae Albers, 1850 - synonym: Liguidae Pilsbry, 1891 - 83 species

2010 taxonomy 
Breure et al. (2010) elevated Bulimulinae to Bulimulidae, Odontostomini to Odontostomidae, Amphibuliminae to Amphibulimidae. 2012 taxonomy 
Breure & Romero (2012) confirmed previous results from 2010, additionally they elevated Simpulopsini to Simpulopsidae. Genera
