斑尾复鰕虎鱼和矛尾复鰕虎鱼同物异名的探讨

Discussion on the synonym of Synechogobius ommaturus and S. hasta

本文依据113尾标本研究表明矛尾复(?)虎鱼Synechogobius hasla(Temmtnck et Schlegel)是斑尾复(?)虎鱼Synechogobius ommaturus(Richardson)的同物异名,不是两个不同的种。

In this paper 113 samples caught along the seashore of Liao-ning province are divided into three types of body length groups, i, c, large, medium and small sized types. Ten fishes of each group are randomly sampled to measure its proportional properties. It is shown that the ratio of length of candal peduncle to height of them is increased and that of head to caudal fin is decreased with the grouth of body length. The result shows that the properties of the small type and the large type fishes are conformed with those of Syncchogobius ommaturus and 8. hasta respectively, and the medium sized type is the transition type of them. In the mean time it is shown that the vertebral number of various sized type is conformed with each other. Then, it is proved that Synecho-gobius hasta is the synonym of S. ommaturus and that it is also not a separate species.
