Summary 1. The pH-optima of protease, amylase, saccharase, maltase and lipase of the marine crab, Thalamita crenata, have been determined. Their optima, except for that of lipase, are high when compared with those of Astacus and Maja. 2. After starvation the midgut gland shows a rhythmic activity after feeding commenced, with two maxima of secretion at 1 and 5–8 hours after feeding. The probable mechanism of this type of secretoric activity is discussed.
