Extract

The tendency among some modern authors to suppress the well-known genus Stephanoceras, Waagen, 1869, is due to sundry misconceptions, combined occasionally with a complete disregard of the Rules of Nomenclature. This raises matters of general interest, and thus a review of the vicissitudes of that genus and a discussion of some related questions may be acceptable to all palaeontologists.
