1 The lagenar macula is rectangular and the smallest of three maculae.2 Many holes were observed in the otoconial membrane of the saccule.The hair bundles of the sensory cells penetrate these holes and occupy half of the hole space.3 The otoconial membrane of the saccule was thinner than those of the utricle and the lagena.4 Otoconia of the lagena were smaller than those of the saccule and the utricle.5 In the striolae of the utricle and lagena, the density of the sensory cells was low compared to the other portion.6 In the sacule, there was a linear portion which divides sensory cells into two groups. These group cells have sensory cilia which are arranged in such manner that they are facing each other. This line is suggestive of a striola.7 Sensory cells with long stereocilia were often seen in the striola region.8 The hair bundles were classified into three types in the utricle, two types in the saccule and the lagena.
