Abstract
The structure of the spiral limbus of the guinea pig and human was observed light microscopically and electron microscopically. The shape of the spiral limbus is quite different. It appears to be shorter in hight and flatter in human. The cellular composition is same both, but in human the number of cells is much less by the replacament with intercellular substance. In the pathological limbus due to the obliteration of the ductus reuniens in the guinea pig, the severe degenerative change was introduced with cochlear hydrops.
