Helminthoglyptinae
The Helminthoglyptinae are a subfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks within the family Xanthonychidae. MolluscaBase eds. (2021). MolluscaBase. Helminthoglyptinae Pilsbry, 1939. Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=994962 on 2021-02-25 This is a large and diverse group of new world snails, ranging in distribution from Alaska through North America to the West Indies, Central America, and as far south as Argentina. The shells are typically of medium to large size, with no apertural teeth but usually with a reflected apertural lip. Anatomy In the species in this family, the diverticulum may be present or absent. They possess a single dart apparatus with one stylophore (dart sac) and two mucus glands. These snails use the love dart as part of their mating behavior. In this subfamily, the number of haploid chromosomes lies between 26 and 30 (according to the values in this t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aperture (mollusc)
The aperture is an opening in certain kinds of mollusc shells: it is the main opening of the shell, where the head-foot part of the body of the animal emerges for locomotion, feeding, etc. The term ''aperture'' is used for the main opening in gastropod shells, scaphopod shells, and also for ''Nautilus'' and ammonite shells. The word is not used to describe bivalve shells, where a natural opening between the two shell valves in the closed position is usually called a ''gape''. Scaphopod shells are tubular, and thus they have two openings: a main anterior aperture and a smaller posterior aperture. As well as the aperture, some gastropod shells have additional openings in their shells for respiration; this is the case in some Fissurellidae (keyhole limpets) where the central smaller opening at the apex of the shell is called an orifice, and in the Haliotidae (abalones) where the row of respiratory openings in the shell are also called orifices.

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Humboldtianidae
Humboldtianidae is an American family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). Anatomy The anatomy of this family is defined by the presence of a diverticulum and three to four dart apparatuses (the love dart is used in mating behaviour). They always have the same number of dart sacs and mucus glands, with two darts per dart sac. The mucus glands are situated on, and open into, the vagina, above the dart sac. Distribution This family of snails occurs in the United States and Mexico. Taxonomy The family Humboldtianidae is classified within the clade Stylommatophora within the clade Eupulmonata Eupulmonata is a taxonomic clade of air-breathing snails. The great majority of this group are land snails and slugs, but some are marine and some are saltmarsh snails that can tolerate salty conditions. Linnean taxonomy *Suborder Eupulmonat .. ...

Epiphragmophoridae
Epiphragmophorinae is a subfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Xanthonychidae (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). This family has no subfamilies. Shileyko (2004) listed 40 species within Epiphragmophorinae. There are about 65 recognized species within Epiphragmophorinae in 2017. Anatomy This family is defined by the absence of a diverticulum. These snails have one dart apparatus with a stylophore (dart sac), and one or two mucus glands that are inserted on the dart sac and on the accessory sac, or at the base of the dart sac.

The sheath of the dart apparatus has two glands. Taxonomy This family is placed within the clade Stylommatophora within the clade Eupulmonata (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
