A-CHATINA.— Plate Xlll. 



Glandina Inincata, Say, Amer. Conch, pi. 20. 

 Eab. Florida. 



This very interesting shell is, without doubt, the Glau- 

 dina Iruncata of Say, according to his figure, but whether 

 it is the original Bulla Iruncata of Gmelin, it is impossible 

 to tell; for Gmelin, like Say in the instance before us, may 

 have confounded two or three species as synonyms under 

 one specific name. A close examination of the characters 

 of the shell under consideration, which, as being the 

 species figured by Say, may as well liave the name truncata 

 assigned to it, will show that it is perfectly distinct. The 

 rib-like stria? have a more elevated plicate structure, and 

 they differ materially in having no indented punctures ; the 

 colouring is also peculiar, the aperture being tinged \vith 

 a rich flesh-pink.

 Lea, Trans. Amer. Phil. Soc. (Extr.) p. 196, pi. 19. f. 78. 

 Hab. Mexico. 



This species of Mr. Lea's approaches very closely to 

 that subsequently named A. Sowerbyana, by Dr. Pfeiff^er, 

 represented at PI. VIIL The white flakes serve never- 

 theless to distinguish it.
