However, depending on how the hooks are numbered, there may be seven hooks in each principal row with an intercalary row of three hooks (

Since there are no morphological differences between the terminal hooks of the principal rows and the intercalary hooks, either method of numbering the hooks is considered to be equally appropriate.

Dollfus' (1942) general observation that bothrial pits may be difficult to detect is undisputed, but the wide range of specimens available for this study and the use of scanning electron microscopy confirms that, in this species, bothrial pits and/or modified microtriches do not exist.
