tin- hln-11 ; for at a particular epoch, of all tlur whorls of the spi** 

 originally possessed by thi* Bulinius, not u ^in^lc urn- remains*. 



PUPA, Lam. 



Have the summit of the shell very obtuse ; the last whorl, in the 

 adult, becoming again narrower than the others, giving it the fornj of 

 an ellipsoid, or sometimes almost that of a cylinder ; the surrounding 

 margin of the apertute tumid and emarginated on the side next to 

 tin- spire by the preceding whorl. Small species, inhabiting wet 

 places, among mosses, &c. 



SomctiiiK's there is no dentation f. 



More commonly there is one in that portion of the aperture 

 which is closed by the penultimate whorl J. 



It is frequently observed inside of the external edgej). 



CHONDRUS, Cuv. 



Have the aperture, as in the last mentioned Pupre, indebted on the 

 side next to the spine by the preceding whorl, and bordered with 

 salient himiiue or teeth; but the form is more ovoid, like that of a 

 common Bulimus. 



Some of them have teeth on the margin of the aperture . 



Others are furnished with more deeply seated laminae^). 



II ! terminates that series of terrestrial Helices, the adult shells of 

 which have a tumid margin round the aperture. 



SUCCINEA, Drop.
