摘要
科鱼类的韦伯氏器的形态与鲤科鱼类的不同，闩骨扁平或长针状，略呈孤形，舟骨“Ｖ”形，由匙状部、上行支、髁状突和舟骨沟构成；间插骨“Ｖ”或钧状，分为间插骨体、水平支、髁状突和上行支四部分；三角骨最发达，含前突、关节突和转换突等部分，韦伯氏器的形态表现出明显的属间差异，可以作为科属间分类的重要依据之一．
In the family Bagridae,the Weberian apparatus consists of the claustrum,the scaphium,the inter-calarium and the tripus. The claustrum is a flat or long spiculate bone,slightly arc-shaped.The scaphi-um is V-shaped,consists of the spatulate,the ascending and the condylar processes and a groove. Theintercalarium is V-or hook-shaped,consists of the body,the horizontal,the condylar and the ascendingprocesses.The tripus is the biggest bone in the Weberian apparatus,consists of the anterior,the articular and the transformator processes. The shape of the Weberian apparatus is different in different species,and it can be used as taxonomic character to distinguish different genus in Bagridae.
