Owen’s First Monograph.

According to DSB X, p.261, “The Atention of the scientific community was first focused on Owen in 1832 when he published Memoir on the Pearly Nautilus. Which was based on a single specimen of this delicate organism that was previously known only by its shell. In this superb piece of descriptive anatomy he also modified Cuvier’s Cephalpoda and proposed two orders that were considered valid until 1894.”
