In the summer of 1969 the author returned to British Honduras, on a Churchill Fellowship, to follow up his previous studies of the manatee Trichecus manatus manatus and two crocodiles Crocodylus acutus and C. moreleti, all ‘Red Book’ species (see ORYX, May 1968). He found a good breeding population of the manatee, but the plight of both crocodiles he describes as desperate.
