Architaenioglossa

Architaenioglossa is a taxonomic group of snails which have gills and often an operculum. They are primarily land and freshwater gastropod mollusks within the clade Caenogastropoda.[1]

Scientific classification
Kingdom: Animalia
Phylum: Mollusca
Class: Gastropoda
Clade: Caenogastropoda
Informal group: Architaenioglossa
Haller, 1890

This "informal group" has been shown to be polyphyletic in a study by Harasewych et al., published in 1998.[2]

Taxonomy

(Families that are exclusively fossil are indicated with a dagger †)

gollark: Did I now.
gollark: I'm sure you'd like to think so.
gollark: It's simple. The initial python bit detects strings which are UTTERLY spacious, and then (in an oddly obfuscated way) ensures that each character in one string exists at least once in the other. Then, it calls the C bit with - due to odd pythonous scoping - the string without the index where they were found to match. The C bit actually does the same thing, calling back into Python afterward. If there is ever an *unmatched* character, it returns false.
gollark: But I posted mine earlier. Four of them, even.
gollark: Except mine, naturally.
