摘　　要：本文解剖观察了鳐类尾部肌肉横切面,计36种50余尾,分隶于19属、15科、4目。对同种不同大小个体亦作了比较分析,其性状稳定;肌肉的形态特征与不同生态类型有密切的关系,可依此分为4种式型6亚型。在不同分类阶元,各有独特的特征,借此可作为鉴别分类依据之一。The present paper deals with the caudal regi nmuscle o f 36 representative species of rays and skates of China, belonging to 19 genera, 15 families and 4 orders. Cross section of the caudal region muscle was made behind the cleaca. In general, the bundle of muscles can be divided into dorsomedian, dorsolateral, lateral, ventromedian, ventrolalcral ones. In some species there are external lateral and external ventral bundles, The observation shows that morphological characters of muscles are closely connected with different ecological types. Four patterns and six subpatterns of caudal muscles of Chinese rays and skates are recognized, according to muscle structures in relation to body form, swimming efficiency and ether ecological factors. Based on the differences of muscle structure, a key to families of Chinese rays and skates is, tentatively presented.
