    genus the female alone is provided with this covering. In Spirilla (E 1060 [F.]) the shell is internal, but chambered and coiled. The internal shell of Sepia, in the form of an oval? calcareous, laminated plate (E 1061 [F.]), is well known under the name of “ Cuttle-bone.” In Loligo it is horny, and consists of a shaft and two lateral expansions or wings (E 1064 [F.]). In Wall Case VI. is a specimen of the entire animal (soft parts and shell) of the Pearly Nautilus : a portion of the shell has been removed to show some of the chambers, and the membranous tube or siphon which traverses them. The organization of this living representative of the extensive series of extinct Cephalopods with chambered shells, which range through the secondary rocks, is described in a quarto volume (published by the College), entitled “ Description of the Pearly Nautilus.” In the same Case is a specimen of the Argonaut or Paper Nautilus, suspended as when floating, with the expanded membranous arms (erroneously supposed to serve as sails) in their natural position, spread over the exterior of the shell, which they form and repair. In the Floor Cabinet which contains the shells of Mollusca, is a series (E 1110 to 1153 [F.]) of specimens illustrating the nature and mode of production of Pearls, which are fully described in the Catalogue.
