A couple of "nick-names" not often seen, which relates to Catalinas. In files of official correspondence on the allocation of various PBYs during WW2, I have seen the terms "Seacats" and "Landcats" sometimes applied to (respectively) the non-amphibious and the amphibious models, merely as a handy (short) reminder of an important difference between these aircraft. Possibly just in case some file reader was a little bit fuzzy as to which model was which - might have caused some embarrassment if the wrong model was sent to an unsuspecting customer.
