The tubules of digestive diverticula in five species of Ptellogastropoda and 11 species of Vetigastropodathe were observed with the tissue preparations by Azan staining. In five kinds of Ptellogastropoda, four to six thick tubules of digestive diverticula extended radially from the extremely short duct which originated from the stomach. And each tubule ramified with the dichotomous branching type, and spread out in the digestive diverticula. In six kinds of Trochidea and three kinds of Turbinidae of Vetigastropodathe, one thick tubule from the very short duct from the stomach extended in the inside of spiral digestive diverticula, ramified with the dichotomous branching type and spread out in the digestive diverticula. However, in Haliotis discus discus of Haliotidae and Scutus (Aviscutum) sinensis of Fissurellidae of Vetigastropoda, the tubule with the monopodial branching type arose from the places of the duct.
