红尾副鳅的亚种分化及其动物地理分析

红尾副鳅（Paracobitis variegtus）广泛分布于黄河、长江和南盘江水系的上游。其背鳍分枝鳍条数目、前鼻孔的形态、头部斑纹、须的长度和前躯的被鳞程度等特征均表明红尾副鳅已分化为两个亚种。两个亚种的分布在地理上是相互隔离的:红尾副鳅指名亚种（P.variegatus variegatus）的分布范围限于黄河、长江水系的上游;而新亚种长鳍副鳅（P.variegatus longidorsalis）则仅分布于南盘江的上游。亚种的分化可能与晚更新世时滇东高原的急剧抬升有关。本文还讨论了Nemachilus berezowskii Gunther 1896和Nemacheilusoxygnathus Regan 1908的分类地位。经查看其模式标本,认为上述两个名称应为红尾副鳅指名亚种的同物异名。

First record of Paraonella platybranchia (Hartman, 1961) (Polychaeta: Paraonidae) from the Yellow Sea

This paper reports for the first time a species of polychaetous family Paraonidae, Paraonella platybranchia (Hartman, 1961), a rare species found previously only in the coast near the boundary between the United States and Mexico, and it was recently discovered in the samples collected in 1982 from Chinese side of the Yellow Sea. This is the first record of the species in China as well as in the Northwest Pacific.
