cated this genus under the name of Polyphemus, found- 

 ing it on the Bulla valuta of Chemnitz, the Achatina 

 glans of Bruguiere. Schumacher, in 1817, adopted this 

 as a distinct genus ; but, as the name Polyphemus had 

 been previously appropriated, he designated it by the 

 name of Glandina. Ferussac also recognized the pecu- 

 liarities of the shell, and made for it a section of his 

 genus Helix, under the name of Cochlicopa. The struct- 

 ure of the animal fully authorizes its separation as a 

 distinct genus ; and yet, although Mr. Say carefully de- 

 scribed the animal as long ago as 1818, most authors 

 have still united it with Achatina, among whom may be 

 mentioned Deshayes and Philippi, the most important 

 recent wi'iters on the subject. The animal is eminently 

 carnivorous, and its favorite resorts are wet and swampy 

 places ; when found in dry places, they are very small. 

 Their eggs are of considerable size, oblong-spheroidal, 

 and covered with a firm, calcareous shell. — [g.]
