Description
M‘Coy (1850) introduced the name as a genus name for monograptids and compared it to ‘Diplograpsis’ (now Diplograptus) introduced for biserial graptolites. Nicholson (1868b) used the genus name, but it survives only as the common name for the group, as it was already used by Barrande (1850) and has never been accepted as a valid genus name.
