Gentlemen,
If you don't care about fastener minutia, then stop reading now.

Slotted nut

This image says it's a castellated nut but is in fact a slotted nut!

Castellated nut

A good number of the images on Google claim slotted nuts are castellated
nuts and vice versa, so you obviously cannot trust the web on everything.
Bottom line... the official source is the Machinery's Handbook. My 16th
Edition,1959 volume printing clearly shows the distinction. It also has
quite a bit of info on Whitworth Fasteners and UNF, UNC fastener markings
that distinguished them from Whitworth.
Cheers,
Curt
