Both scsh and tcsh are from the csh family of shells.

posh, zsh, mksh, bash, dash, and ksh are from the Bourne family of shells

No idea what slsh or mosh are

Why bother?  csh syntax is non-standard, and in my opinion, it is ugly
(others around here disagree, or tcsh would have died long ago, but
that's a different story - it's mostly people that were on a system that
picked csh as its default shell long before standardization picked
Bourne over csh syntax).
