La cavidad bucal eoitelio un epitelio cilindrico estratificado. Tracto digestivo; Conoidea; Turridae; Polystira albida. In the present investigation it was realized a histological characterization of the digestive tract of Polystira albida Toxoglossa: Turridaeby using optic microscopy of specimens collected in Sonda de Campeche. Results of analysis show that lips, mouth and proboscis present a simple columnar epithelium with cilia.

Buccal cavity has a stratified columnar epithelium. Esophagus presents a simple columnar epithelium with acidophilic granular glandular cells proteic natureand it is the place where digestion starts.

Stomach is divided estratifivado three histological regions that have two epithelial types, simple columnar with cilia and without one; the first is formed by a lot of acidophilic and basophilic glandular cells proteic and glycoproteic nature respectivelyand the second only contains acidophilic glandular cells.


Querayinizado gland is constituted by tubule-acinous adenomers with acidophilic and basophilic glandular cells in different grades of secretion, ;lano ducts have simple columnar epithelium with cilia and scarcely glandular cells. Intestine is divided in five histological regions, the first presents atyphlosole with two types of epithelium, simple columnar with stratified border; the rest of the tract has simple columnar epithelium with cilia, acidophilic granular glandular cells and folds of different sizes that increase or reduce the cavity duct.

Based on previous this, we conclude that in this study exist differences principally in front region of digestive tract buccal cavity, esophagus and stomach compared to general descriptions realized for Prosobranchia subclass.
