Abstract

Attention is drawn to a hitherto overlooked note by Portlock, dated 1837, which is of significance to the dates and type specimens of the trilobite species Celtencrinurus multisegmentatus (Portlock) and Cryptolithus latus Portlock, both of which have been assumed to have dated from Portlock's 1843 Report.
