【肺螺类】
肺螺类（学名：Pulmonata），亦作有肺类，旧作有肺目、肺螺目或肺螺亚纲，是腹足纲异鳃类支序之下的一个非正式群组。这个群组包括有螺和蛞蝓，均可以透过其外套膜肺（pallial lung）而不是鳃来呼吸空气。本群组除了包括有蜗牛和淡水螺，还包括多个海螺的科。
传统定义的肺螺类分类单元的物种在Jörger et al. (2010)被发现原来是个多系群。肺螺类已知从石炭纪开始就已经开始出现，直到现在。
肺螺类物种有一个心室和一个肾脏，还有一个相互连接、左右对称的神经系统。外套膜腔位于身体的右侧，而且没有鳃，而是演变成一个布满血管的肺。大多数物种都有壳，但没有口盖，而且本分类元还包括有几种没有外壳的蛞蝓。肺类类物种都雌雄间性，部份群组​还拥有用作交配的恋矢（love darts）

==2010年分类==
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.
