willingly change their places of abode, bnt subsist on 

 animal or vegetable food brought by marine currents 

 within reach of their extensile snouts. The female 

 carries her egg-cases under the neck in front of the foot 

 until the fry are hatched. According to Loven the 

 dental apparatus is nearly the same in C. Hungaricus 

 and Calyptrcea Chinensis ; so that these genera must be 

 closely allied. But the internal appendage in Calyptr&a 

 and other genera belonging to the same family indicates 

 a peculiar structure of the animal which is wanting in 

 Capulus. 



D'Argenville called it Cabochon. It is the genus 

 Mitra Hungarica of Klein, and Pileopsis of Lamarck. 

 About a dozen other synonyms have been cited by 

 Herrmannsen.

Body whitish, with a yellowish or brown tint : mantle either 

 the same colour as the rest of the body, and thickly covered 

 with minute milk-white specks, or else pinkish-white or red 

 with a border of bright yellow or orange ; margin thickened, 

 and fringed with fine filaments : head broad and thick, with 

 produced lips so as to make the extremity of the muzzle appear 

 cloven : tentacles variable in length, sometimes of a white or 

 yellowish colour : eyes small : foot bordered in front by a 

 puckered ruff or membrane. 



Shell not unlike a cornucopia, or an ancient fool's or 

 jester's cap, with a roundish base, the height of the cone 

 depending on the comparative dilatation of this latter part ; it is 

 rather thin, semitransparent, and of a dull hue beneath the 

 epidermis : sculpture, numerous fine ribs which radiate from 

 the beak towards the margin, near which they almost disap- 

 pear, besides very slight and close-set minute transverse striae 

 between the ribs ; marks of growth conspicuous but irregular :
