The animal kingdom, arranged after its organization : forming a natural history of animals, and an introduction to comparative anatomy . 306 Fip. 1S4.—Murcx tenuispiua. iHE MuREX, Linn.*—Embraces all shells whose canal is elongate and straight. I have found in the animals of all the sub-genera a proboscis ; approximated long tentacula, with the eyes external at their base; a horny oper-culum, and no veil over the head : they otherwise resemble the Buccina, except in the length of thesiphon. Bruguieres divided them into two genera, subsequently subdivided into others by Lamarckand Montfort. Murex, Brug-., are all shells with a salient straight canal, and with varices across the whorls. M. Lamarckreserves this name specially to those in which the varices are not contigTious, so as to make two opposite rows. Iftheir canal is long- and slender, and the varices are armed with spines, they belong to the Murex of Montfort. If the varices are merely nodulous,they constitute his Brontes. Some,with a canal of moderate length,have projecting tubes between thespinous varices which penetratethe shell; and these are the Ty-phis, Mon
