The epithelia of the olfactory organ of two cyprinodontoid fish species were studied both by transmission and scanning electron microscopy. The relatively flat floor of the organ is covered by sensory and nonsensory epithelia. The latter is distributed in the form of bands or ridges separating distinct areas of sensory epithelium. Differences between the olfactory organs of the two species investigated related only to the topography and quantitative distribution of the epithelia. Their ultrastructural features are very similar. The nonsensory stratified squamous epithelium contains numerous goblet cells and surface cells provided with microridges. A hypothetical function of the microridges is discussed. The sensory epithelium consists mainly of basal, supporting, and two types of sensory cells, i.e., ciliated and microvillous receptor cells. The cilia exhibitapredominant 9+0 microtubule pattern. Both epithelia are covered by a mucus layer in which all surface structures seem to be embedded. The possible nature, origin, and movement mechanisms of the mucus are discussed.
通过透射电子显微镜和扫描电子显微镜对两种鲤齿目鱼类嗅觉器官的上皮组织进行了研究。该器官相对平坦的底部被感觉上皮和非感觉上皮覆盖。后者以带状或脊状分布，分隔着感觉上皮的不同区域。所研究的两种鱼类嗅觉器官之间的差异仅与上皮组织的地形和定量分布有关。它们的超微结构特征非常相似。非感觉复层鳞状上皮包含大量杯状细胞和具有微嵴的表面细胞。文中讨论了微嵴的一种假设功能。感觉上皮主要由基底细胞、支持细胞和两种感觉细胞组成，即纤毛受体细胞和微绒毛受体细胞。纤毛呈现出主要的9+0微管模式。两种上皮都被一层黏液层覆盖，所有表面结构似乎都嵌入其中。文中讨论了黏液的可能性质、来源和运动机制。
