  在原來的《旁得和林德伯格的腹足類分類 (1997年)》,本支序是一個目級分類元,包括下列各個分類元:

  根據《布歇特和洛克羅伊的腹足類分類 (2005年)》,Glacidorboidea被搬到異鰓類支序之下的下異鰓類群組,本分類餘下下列各個分類:

  包括基眼類非正式群組及真有肺類支序。

  基眼類(Basommatophora)非正式群組包括喜溼螺類(Hygrophila)支序和下列兩個總科:

  喜溼螺類(Hygrophila)支序包括下列四個總科:

  真有肺類(Eupulmonata)支序包括the clades Systellommatophora and Stylommatophora

  收眼類支序(Systellommatophora = Gymnomorpha)之下有兩總科,分別為:

  Contains the subclades Elasmognatha, Orthurethra and the informal group Sigmurethra

  Two superfamilies belongs to clade Sigmurethra, but they are not in the limacoid clade.

  Jörger "et al." (2010) analyzed major groups within the Heterobranchia using genetic data and found that Pulmonata as traditionally defined was polyphyletic, for instance some pulmonates were more closely related to Sacoglossa and Acochlidia. They proposed the more inclusive taxon Panpulmonata to unite the clades Siphonarioidea, Sacoglossa, Glacidorboidea, Pyramidelloidea, Amphiboloidea, Hygrophila, Acochlidia and Eupulmonata.
肺螺類(學名:),亦作有肺類,舊作有肺目、肺螺目或肺螺亞綱,是腹足綱異鰓類支序之下的一個非正式群組。這個群組包括有螺和蛞蝓,均可以透過其外套膜肺(pallial lung)而不是鰓來呼吸空氣。本群組除了包括有蝸牛和淡水螺,還包括多個海螺的科。
