UNIVALVES, HELIX. 115 



the H. haemastonia, which is admired for its elegant band- 

 ings and rose colored lips. A black lipped variety of this 

 shell has lately been discovered, which is also extremely 

 rare; the body of the shell being pink, forms a beautiful 

 contrast with its jet lips. 



Of the elongated or tapering Helices, may be particu- 

 larized the H. decollata, H. scalaris, H. circinata, (which 

 has some resemblance to the Turbo scalaris), H. columna, 

 and the H. stagnorum, a fresh- water species. 



The last division contains the ovate and imperforated 

 species; of which the H. pupa, H. barbara, H. amarula, 

 H. stagnalis, H. fragilis, and H. palustris, may be referred 

 to as examples. 



Many of the Helices inhabit aquatic plants instanding- 

 waters, lakes, ponds, and ditches: others are found on 

 trees and shrubs, and some harbour among rotten wood.
