The general structural organization, receptor and nervous elements of tentacular sensory organs, statocysts, eyes, osphradium as well as receptor elements of skin of body and head were investigated in the land prosobranch mollusk Pomatias elegans. The structure of eyes, statocysts and osphradium of P. elegans, with the exception of some details, does not differ principally from the structure of corresponding sensory organs of the primarily water-dwelling Prosobranchia. The head tentacles are complex, specialized sensory formations, similar to tentacular organs of land pulmonates. They had a specialized sensory area, featured in the apex of the tentacle, and apical and basal tentacular ganglia. The glomerula-like formations are revealed in the neuropile of the apical tentacular ganglion. Almost all the receptor cells in skin and sensory organs of P. elegans are intra-epithelial. The regularities of evolution of chemosensory systems of gastropods arising at multiple land intrusion are discussed.
对陆地前鳃亚纲软体动物秀丽扁卷螺的触手感觉器官、平衡囊、眼睛、嗅检器的一般结构组织、感受器和神经元件以及身体和头部皮肤的感受器元件进行了研究。秀丽扁卷螺的眼睛、平衡囊和嗅检器的结构，除了一些细节外，与主要生活在水中的前鳃亚纲相应感觉器官的结构并无本质区别。头部触手是复杂的、特化的感觉结构，类似于陆地肺螺亚纲的触手器官。它们有一个特化的感觉区域，位于触手顶端，还有顶端和基部触手神经节。在顶端触手神经节的神经纤维网中发现了肾小球样结构。秀丽扁卷螺皮肤和感觉器官中的几乎所有感受器细胞都是上皮内的。讨论了腹足纲动物在多次登陆过程中化学感觉系统的进化规律。
