CAPULUs. 269 



willingly change their places of abode,, but 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 CalyptrcBa Chinensis ; so that these genera must be 

 closely allied. But the internal appendage in Calyptraea 

 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.
