摘要
本文报道了黄渤海产江豚的外形和骨骼特征,并指出黄渤海产江豚与东海、长江产江豚在外形和骨髂上有较大差异。由于Pilleri和Gihr把中国的江豚曾另定名为一个独立种,因此作者对其分类问题进行了初步探讨,认为黄渤海产江豚与东海、长江产江豚是两个不同的亚种。本文还对江豚的生殖期进行了初步分析。

The external measurement and skull dimensions weregiven in Tables 1. and 2.According to our observation and measurement it wasfound that the extetrnal appearance and the shape of skull of our specimenswere quite different from those of Changjiang River. Thus the authors consideredthat they should be divided into two subspecies.
