Abstract
The genus Multiceps has come under intense observation recently and the validity of the various species has been considered. The hook, being of a chitinous nature and therefore presumably of a less variable disposition than most other points, has been used for specific diagnosis, though as has been shown earlier, even this structure is not entirely satisfactory. But there is no other structure that is more satisfactory. When the information has been available, the blade length has been used as this is the most constant part of the hook. The small hook is of little or no diagnostic value. In many cases, however, only the range of the total length has been known.
