本文在前文对三种生态类型的相似金丝雀生活史研究的基础上，比较了成鱼的形态特征。尽管在身体形态上有明显的相似之处，但河流型在身体一侧的颜色模式(图1)以及脊椎、胸鳍和第一背鳍的数量(表1；图2)上明显不同于其他两种类型(两栖和湖型)。考虑到成熟卵的大小和数量在新孵化的幼虫的大小和发育阶段具有更明显的特征，似乎可以得出结论，河流型应被称为Tukugobius Herre，1927，而不是Rhinogobius属。另外两个类型，即两栖类型和湖泊类型，它们之间的区别不比种内变异更大(表1；图2和图3)。因此，河流型被命名为Tukugobius flumineus，其他两种类型保留了Rhinogobius similis Gill的习惯名称。
Succeeding the life history study in the previous paper of three ecological types of “Rhinogobius similis”, the morphological characters of adult fish are compared in the present paper. In spite of the apparent similarities in the body form, the fluvial type is clearly different from the other two types (the amphidromous and lacustrine types) in the colour pattern on the body side (Fig. 1), and in the number of vertebrae, pectoral and first dorsal fin rays (Table 1; Fig. 2). Considering the more distinctive features in the size and number of mature eggs, in the size and developmental stage of newly hatched larvae as reported in the previous paper, it seems appropriate to conclude that the fluvial type is to be referred to the genus Tukugobius HERRE, 1927 instead of the genus Rhinogobius. The other two types, i. e., amphidromous and lacustrine types have no more distinctions with each other than intraspecific variations (Table 1; Figs. 2 and 3). Thus, the fluvial type is named as Tukugobius flumineus and the other two types retain the customary name Rhinogobius similis GILL.
