在识别经常出现在印度-西太平洋上斜坡的康氏鳗属BathycongrusOgilby，1898的物种时遇到的困难主要是因为这些鳗鱼几乎没有独特的外部特征。由于尾尖的频繁丧失和随后的再生，在这里识别的七个物种之间的身体比例的差异不容易评估。在犁骨齿的大小和数量上存在差异，尽管这些差异不容易量化，以及椎骨的数量。然而，这两个字符的组合允许识别大/小齿形式以及具有低计数、中计数和高计数椎骨数量的形式。这里的解决办法是将16个命名种中的一些归为一组。因此，在这个帐户中确认了7个印度西太平洋种。UranocongerFowler，1934与Bathycongrus同义。幼虫特征，特别是肌节的数量，可能有助于解决种鉴定的问题。给出了该物种的检索表。
Difficulties in identifying the species of the congrid eel genusBathycongrusOgilby, 1898 that frequent the upper slope in the Indo‐west Pacific arise principally because these eels possess very few distinctive external characters. The differences in body proportions between the seven species that are recognized here are not easy to evaluate because of the frequent loss and subsequent regrowth of the tail tip. There are differences in the size and number of vomerine teeth, though these are not readily quantifiable, and in the number of vertebrae. However, the combination of these two characters allows the recognition of large/small‐toothed forms and those with low‐count, mid‐count, and high‐count vertebral numbers. The solution here has been to lump together some of the 16 nominal species.Accordingly, seven Indo‐west Pacific species are recognized in this account.UranocongerFowler, 1934 is synonymized withBathycongrus.Larval characters, especially the number of myomeres, may be of some assistance in resolving the problems of species identification. A key to the species is given.
