Abstract: 1. While ammonia was found to be the principal nitrogenous excretory product of Pagurus samuelis and P. granosimanus, substantial amounts of urea, allantoic acid, and allantoin were also detected. Small amounts of uric are also excreted. 2. Individual crabs showed considerable variation in the amounts of the various nitrogenous compounds excreted. 3. No difference in excretory products was observed between the species tested.
