Not illustrated. 1883 Excerpt: ...Gasteropods, and is divisible into two sections, termed respectively Siphonostomata and Holostomaht, according as the aperture of the shell is notched or produced into a canal, or is simply rounded and "entire." The Siphonostomata, of which the common Whelk (Bticcinum vndatum) may be taken as an example, are all marine, and are mostly carnivorous in their habits. The following families are comprised in this section: --Strombida (Wingshells), Afiiricidce, Buccinidce (Whelks), Conidce (Cones), Volutitia, and Cypratidce (Cowries). The Holostomata, of which the Common Periwinkle (Littorina littorca) is a good example, are either spiral or limpetshaped, in some few instances tubular, or multivalve; the aperture of the shell being in most cases entire. They are mostly plant-eaters, and they may be either marine or inhabitants of fresh water. The following families are included in this section: Naticii(?, Pyrawidelliita, Cerithiadcc, Melaniada, TtirritcltidcR, Littorinidce (Periwinkles), Puludinidtx (River-snails) Neritidiz, Turbinidce (Top-shells), Haliotidx (Ear-shells), Fissurellida (Key-hole Limpets), Calyptrxidie (Bonnet Limpets), Patdlida (Limpets), Dcntalida (Tooth-shells), and Chitonida. fig. no.--Gasteropoda, a Holostomatous shell (Titrritflla comtitunU) b Siphonostomatous shell (Buccinum ttndatHiri). Order II. Opisthobranchiata.--This order is defined as follows: --"Shell rudimentary, or wanting. Branchice arborescent or fasciculated, not contained in a special cavity, but more or less completely exposed on the back and sides, towards the rear (opisthfti) of the body. Sexes united."--M.-Edwards. (See Woodward's 'Manual.') The Opisthobranehiata, or "Sea-slugs," may be divided into two sections, the Tectibranchiata and Nudibranch...
