Additional machaeridian specimens from the Wether Law Linn Formation (Telychian) have increased our knowledge of this poorly recorded but abundant group in the Pentland Hills, located a few kilometres SE of Edinburgh. A new type of anterior outer shell plate is described and is compared with material previously described from the same horizon and locality. Moreover, a new species of Plumulites is established on the basis of a disarticulated but close association of shell plates.
