Abstract: 1. The hepatopancreas was found to be the most important producer of amylase in Pagurus samuelis. 2. The foregut, though much weaker, was also shown to have significant amylase activity. 3. The other portions of the digestive system had activities equal to or lower than muscle tissue. This activity is probably the result of amylase in the hemolymph and blood. 4. Under laboratory condition the pH optimum was found to be 7.0. 5. Under the same conditions, the temperature optimum was found to be near 35 degrees Celsius. 6. Some evidence for the possible presence of a B-amylase was found.
