【Abstract】 The genus Funiculus Heude, 1888, comprising F. delavayanus, F. debilis, F. probates, F. asbestinus, F. coriaceus and F. laurentianus before this work, was revised in brief. The 7th species Funiculus songi sp. nov. was described from Yunnan, based on the diagnostic shell shape and the apertural structure. Besides, this species gives the chance for learning the anatomy of the genus.更多还原
