The Pamphlet Collection of Sir Robert Stout: Volume 64

Cases 34 and 35

Cases 34 and 35

contain the Cephalopoda, the Pteropoda, and the Heteropoda. Among the first we have the Paper Nautilur (Argonauto argo), both animal and shell; the Octopus (Octopus vulgaris), the Squid (Loligo vulgaris), the [unclear: Sepia] (Sepia officinalis), and the extinct Belemnites, which page 25 very much resembled the Sepia, but of which only the internal shell is preserved. The recent species are illustrated by very accurate glass models, as it is impossible to exhibit real specimens so that they can be understood.

In Case 35 we have the Nautilus (Nautilus pompiliut) and the extinct genera of Ammonites, Orthoceras, &c.

The Pteropoda are oceanic animals that swim by means of two fin-like arms. The glass model of Clio borealis will explain the shape of the animal; the rest are only shells The Heteropoda are also free swimming oceanic molluscs, but swim by means of their foot. Dentalium is sometimes put into a separate order.
