There was also the two Latham 47P (Postal variants powered by 500 hp HS 12Hbs instead of Farman 12We engines. Except a reduced crew of 3, I believe otherwise unchanged.
 
In Onera Archive,they mentioned Type-63,as a seaplane or flying boat Project of 1929 ?.

From TU 218,the Latham Type-63 was a three-seat recce and coast guard seaplane,with a high-
wing monoplane shape,and powered by one 650 hp pusher engine,mounted above the wing,
it remained a Project,but later developed with some improvements into Type-110.

The only way to determine which planes are mentioned in Latham articles is to look at their engine specs. First the 1918 3x340hp Panhard H.5 seaplane
